(Part 2) Best household ventilation fans according to redditors
We found 631 Reddit comments discussing the best household ventilation fans. We ranked the 172 resulting products by number of redditors who mentioned them. Here are the products ranked 21-40. You can also go back to the previous section.
Hey! So what I did was buy this controller and then add on the fans wherever I wanted them. These parts are made for audio visual racks so they look good and are quiet so it's not an eye sore. I highly recommend looking at "AC Infinitys" other stuff as they have some new fans that I like. Easiest solution for you might just be something like this.
>I don't think I've ever seen a bathroom fan that actually.... fans.
Builder-grade fans are disappointing in this respect. Many in this sub sing the praises of more higher-end fans.
The Panasonic WhisperCeiling FV-15VQ5 ($135), for example, moves 150 cubic feet of air per minute, yet it only has a sone level of 0.3.
You're talking about moving air in & out of your cabinet.
This is inadequate.
You need to be talking about moving air in & out of the closet.
Three options:
Bathroom Exhaust Fan
Stupid bathroom exhaust fan sucks hot air out of closet and dumps it into the plenum space above the ceiling tiles.
Totally Ghetto.
Highly recommend you talk to building HVAC team, and perhaps dump exhaust into an HVAC return air duct.
APC ACF301
That cooling fan gets installed in the wall of your wiring closet.
When heat inside closet exceeds X then the fans kick on to pull the hot air out, and dump it in the hallway.
This is not an elegant solution - but it DOES work, up to a certain number of BTUs.
MovinCool Portable AC
These can run 24x7x365 for years. Just be sure to install a permanent drain for condensate water.
PLEASE perform basic annual maintenance (remove & wash or replace the intake air filters & inspect the drainage tubes for fungal growth).
They will require hot air exhaust either to the ceiling plenum, or to an HVAC return duct.
Because putting electronics right next to sources of wind and rain is bad. Also it would make installation require climbing a ladder and removing siding or roofing. Same with cleaning.
Anyway, nearly silent bathroom fans cost like $10-$20 more than the obnoxious loud ones. There is no reason to buy the loud ones. I bought a large Panasonic fan for a large bathroom, it's far quieter than the contractor fan in our tiny bathroom despite it being 3X the CFM or more. I think there is a new version but this is what we bought, has been working great for a a few years so far https://www.amazon.com/gp/product/B003U9TNG0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
In addition to contractors saving $10 by giving you a horrible fan, they may have installed it wrong. If you attach it to ridged pipe, it will vibrate the pipe. When I installed mine I followed the instructions[1] and use a small section of flexible pipe to make the connection from the fan to the rigid pipe.
[1] It's unreal how uncommon this is. Virtually everyone who worked on my bathroom wanted to ignore the of the instruction on the products they used and do self-defeating idiocy instead. Like paint "water proof" paint onto a water proof membrane, then install a water proof membrane on top of that by... driving nails through all three.
Hey, I JUST came off building a setup and it cost me $750 total. We have 3 plants in there right now. I have the entire list with amazon links or store suggestions.
Item| Price | Where To Buy
---|---|----
Tent| $95| We bought this one, I don't know if it's worth spending a lot on anything more expensive. For a smaller option I just got a second with good reviews but can't vouch for it yet.
Lights/Hood/Ballast| $140| I got the 600W set, but 400W would make cooling MUCH easier and still get a big yield. For LEDs at similar price, Viparspectra 300W x2 or a single 600W eliminates need for extra cooling potentially (not included here, we used fans from around the house)
ph Test+Control Kit | $25| GET THIS. The water must be pH'd properly for your babies' health.
Cloth Pots| $20 | These are better for aeration, water flow, training, etc. Cheap and reusable too.
Nutrients | $50 | I got the Fox Farms Trio, but there are many good options out there.
Fan + Filter | $150 | This is huge and might be overkill for you. Make sure whatever you get fits your tent vents (This one fits the Apollo tent above with 6" vents).
Ducting | $20 | Connect fan to filter, to tent, to wherever. Might want multiple sizes, check tent vent sizes.
Foil Tape, Metallic | $10 | Here. Metal Duct tape is best duct tape.
Fan Speed Controller | $20 | Useful for if you do get a fan that is slightly overkill!
Fox Farms Ocean Forest | $15 - $40 | You can buy it online and I did for my first 3 bags....then I found it in a local store for $15. There is some controversy with FF lately, it's not organic FYI. There are tutorials on making your own soil if you care, but I like this because I didn't have to use nutes for 3-4 weeks.
Humidifier | $30 | This is the exact one I have. We're in winter so I need it to keep humidity up, you may not.
Dehumidifier | $40 | There are plenty for this much. You may not need this either.
Cal-Mag | $20 | I haven't needed it yet but it's best to have on hand if you do!
Seeds | $75 | I bought from Attitude, chose stealth, and bought like 15 seeds?, so it was expensive. You can get seeds for less.
Jiffy Pellets | $10 | Used to start seeds. There are other options.
Total | $745 | If you buy all this stuff, you have potentially even more than you need to get started, with room for 3-4x more plants than these boxes, and with nutrients to last you for a long long time!
Hope this helps! I'd hate to see you drop so much on it when you don't need to at all.
I got the mini k40 (would not do that again). It works great, but I didn't know it at the time that I would be getting a weaker laser. I was about a week too late learning about tube sizes being the better way to know the true wattage.
I have done a series of upgrades and then re-dos. So hopefully you can learn a few things from all my tinkering.
Analog Milliamp Meter
I bought this meter. I followed this link for the install.
Exhaust
I initially went with an inline 3" bilge pump that had a corresponding 3d printed exhaust mount. It was ok, but in the end I just wasn't good enough when I started cutting more leather/wood.
So I went a little overboard, but I am glad I did. I went with this blower instead. I made my own 3D printed mount for it. I printed 2 adapters for the blower to fit 4" ducting and then routed it up and outside my garage.
I also removed the small internal duct thing prior to installing the new exhaust. it gives me a little more cutting room as well.
Air Assist
I went with the Light to Object head and bought a new lens to fit it.
Drag Chain
I bought a 10x10 drag chain off amazon. I had originally printed one, it was ok, but I recently switched up the mounting of the drag chain to run along the X gantry which gave me a little more room to cut.
Laser Aim Assist
I made a mash of 2 different thingverse designs to hold 2 red line lasers and where they intersect is my laser beam. It works well, I made it this way originally when I had an adjustable table. Honestly, now I should switch back to a single red dot, but I am too lazy. The two lines will sometimes move on me so I end up having to do a test fire every so often to ensure they are lined up properly.
Spring Loaded Adjustable Bed
I followed this guide
Hopefully this helps you out a bit.
YVW.
links to stuff:
I'm adding a thing. Get a programmable thermostat. It's $40. Hook your exhaust fan to it, and set it for 75 degrees (mine go off at 73, and on at 78). Change that number, if you are in winter, or summer. . .these plants do fine as long as their range isn't huge. You can flower at 80 degrees, or 65.
okay, enough typing. hope this goes amazing for you. if nothing else. . .you'll have the right gear. especially the right light and a reliable inline. that's 90% of worries.
I agree with you. And for about the same price, you get a much better and much quieter fan. I have two Panasonic WhisperCeiling 110 CFM fans and they are amazing. I paired them with a discrete timer switch and I feel like i'm living in luxury. Very easy to install. It appears Amazon is out of them right now, maybe discontinued the model, not sure.
I'm a building inspector in Washington state. This sounds about like our ventilation code.
Positive drainage 'plane' is probably what you are looking for. Ideally, IF you had any condensation In your duct, they want you to slope it to the exit so it would drain outside, and not back inside.
We have a colder climate here than in Texas, and I haven't heard anyone mention it.
However, you still want to ventilate your bathrooms, kitchens,and laundry rooms because of all the moisture from bathing, cooking and doing laundry.
You choose, continuous ventilation at 20cfm, or intermittent ventilation at higher cfm(like 80-100).
1.5 sones is an indicator of how loud the fan is. That's a crappy loud, cheap low cfm fan....which means you'll hate hearing it run, and means you're likely to turn it off too soon. This means you'll get mold in your home...
Spend $120bucks on Amazon and get a better, quieter fan (Panasonic 80 cfm) which can run continous, OR intermittently.
www.amazon.com/gp/aw/d/B003TJAGO4/ref=mp_s_a_1_1?ie=UTF8&qid=1521439754&sr=8-1&pi=AC_SX236_SY340_FMwebp_QL65&keywords=panasonic+bathroom+fan&dpPl=1&dpID=41dkHb21dvL&ref=plSrch
As far as ducting... it sounds like they want you insulate (R-6) your ducts. This will likely also help with preventing any condensate inside. And it appears they won't allow a flexible connection at the exterior vent termination....don't know why though.
Almost all modern fans come with energy star rating, and backdraft dampers.
Electric requirement is for GFCI. Kinda stupid since fans are in ceilings, even in bathrooms, so no real danger of electrical shock...but not a bad idea I guess.
Good luck.
I've owned my first home for 3 years and two years ago I designed and was the general contractor for an incredible master bedroom/bath addition.
Suggestions, my house has a one piece sink/counter and it's wonderful and easy to clean and seamless - love it. Highly recommend. Rectangular sinks are popular right now, don't do it--most sinks are oval for a reason (I have rectangle and I've had to relearn how to use a sink and it's too shallow and I don't like it).
I'd recommend not doing tile in your bath/shower area and getting a single vinyl piece like what you currently have (but not green). The shower inserts are easy to clean, elegant, and you can even buy them with a tile design that looks real but is still super easy to clean. Showers should always have extendable shower head arms to make cleaning easier. I'd get one of those curved shower curtain rods to make the shower feel wider. Add recessed lighting above the shower and a few more recessed lights in the room.
For my bathroom addition, I got this fan: https://www.amazon.com/dp/B003TJAGO4/_encoding=UTF8?coliid=IG66NQLIR3JQR&colid=1BWCRY8EQNMEF and it's very quiet, not too expensive, and works really well - it was a Reddit recommendation in several different threads and I'm glad I got it.
How many bathrooms are in your house? Is this the master bathroom? That would determine some choices for me. Does that set of doors on the right hide a linen closet or is it the washer/dryer? If you're taking the room down to the studs and those doors hide a linen closet or a washer/dryer or something else? Consider how much linen closet space you need. If it's a linen closet and if this is the master bathroom or a 'kid' bathroom, I'd recommend trying to get a double sink in here and making the linen closet smaller. If it's laundry, then obviously keep it as a laundry room.
Good idea on removing all the tile and replacing with floor tile and drwall. I'd omit the cabinet above the sink and get a bathroom mirror that will show more of your reflection (especially make your belt area visible) and have storage behind the bathroom mirror. A mirror like this from Ikea would give you a lot of storage space (http://www.ikea.com/us/en/catalog/products/20205171/) - my bathroom mirror is similar but has mirror on the inside which is a nice feature. I wish I had installed the mirror cabinet flush with the wall instead of popping out a few inches. I had the electrician put an outlet near the bottom of the toilet (I saw in a bunch of magazines) and several near the sinks for shaving and electric toothbrushes. I also have a small linen closet in my bathroom and had the electrician put an outlet in there so I could leave my hair dryer plugged in all the time. It's the little things! Think about how you use your space and what you want out of it.
Is the furnace running non-stop, or does it turn off intermittently? If it's running non-stop, it's undersized.
If it is turning off intermittently, then it sounds like the duct work wasn't properly configured, or if the unit was upgraded, the blower wasn't properly specced. To solve this easily, but a register fan. It will move more air down stairs to fix the problem. There are cheaper models than the one I listed. There are models for ceiling vents, floor vents, and wall vents.
AC Infinity AIRTAP T4, Quiet Register Booster Fan with Thermostat Control. Heating Cooling AC Vent. Fits 4” x 10” Register Holes. https://www.amazon.com/dp/B0792QR5YT/ref=cm_sw_r_cp_apa_DBQ.BbBQZJ180
I own both a gen 4 and a gen 5 FSL hobby laser, and I really like them both. There's a decent community forum here:
http://fslusers.freeforums.org/
You'll get some good answers there.
For 1), I don't know; I don't have their exhaust fan. They didn't have it available when I bought mine, but it looks decent enough. Without seeing it in person I can't comment on if it's worth $200 or not, but I use this one on one of my lasers: http://www.amazon.com/gp/product/B000O8D0IC?psc=1&redirect=true&ref_=oh_aui_search_detailpage and it's loud but works well. On my other I use this one: http://www.amazon.com/gp/product/B005XNNYMU?psc=1&redirect=true&ref_=oh_aui_search_detailpage and it's much quieter and also works very well. Granted my ducting is 6" to match, but I like it.
For 2), what diameter items? I got my rotary for free from some promotion/preorder/I can't remember and I actually have barely used it. It's hard to fit into the machine, as it raises items up off the floor of the laser, and there isn't much vertical height left over. I'd estimate you could only do roughly 1/2" diameter stuff without removing the floor of the laser (which isn't hard), but even then you'll likely only get to 1" or so. You'd need to remove the floor and set it up on something to get anything bigger. The removable floor is pretty nice; I took mine out and haven't looked back.
For 3), I can't comment on the cost of the 45W tube, as I didn't get one with mine, but I don't see it being worth it. You can get a whole second tube from LightObject for less than the cost of "upgrading" that first tube: http://www.lightobject.com/SP-35W-CO2-Sealed-Laser-Tube-for-Small-K40-laser-engraving-machine-P208.aspx Note that, despite being labeled as a "40W" laser, most of these small machines are actually about 30-32W. 40W refers to the peak pulse power when starting up; it's not a continuous run rating.
As far as compressors go, I haven't ever run without one. It helps TREMENDOUSLY when vector cutting and helps a LOT to keep your lens clean. Their compressor is OK but it's a bit pricey; I'd look around and see if I could find a continuous-duty-rated compressor for cheaper than that.
Don't get their water chillers either. The $600 one is just a radiator and a fan, and won't chill your water much. You get WAY more bang for your buck from a 5 gallon bucket. If you run it for a long time, freeze gallon jugs of water and put them in the bucket. I've run 100% power vector cutting jobs for 2 hours at a time with a gallon of ice in there, and it's just about right. You might need another half gallon; it's been a while since I've used that method. Their "Advanced chiller" looks decent, but it's WAY overpriced. An equivalent unit from here: http://www.vminnovations.com/search/index.html?q=AACH25 is $425 for a brand new one, and less than $300 for a refurb, and it's actually a refrigerant based unit. I installed an 80W tube in mine (not their official kit) and use that chiller and it works great.
Last, don't get their 90W upgrade kit either unless you have a REALLY good reason to. A tube and PSU cost around $1100, so you're paying nearly $2000 for brackets and a wiring harness. It's just not a good value, but then again installing your own 80W tube isn't exactly a walk in the park if you don't have some fabrication tools handy.
I hope that helps. For what it's worth I really like my lasers and they have served me well. If I get another laser it'll probably be a direct import from GWeike, but that's only because I've been using the FSL lasers for so long and have learned a TON from them.
Also a fan of enginerding cheaper solutions:
I live in the south so I punched through the wall and have an inline moving air out of a vent coupled with a space heater does the trick even when cold... like the whopping 50 degree winters here...
But for heat retention I would emulate the tree growers solutions (duct fan hooked to a charcoal filter ). Keep in mind even the "quiet" duct fans still make a loud hum if exposed in your garage. Model I bought.
And potentially expect a knock on the door...but hey, relocate your grow house somewhere else first and it wont be a problem.jk
Seriously though, I'd weigh the costs of making something + the filter media vs buying a commercial air cleaner as those suckers really work. I know if I had to retain air and had 2k to drop I'd buy one.
This is the one we used for a small bathroom. It's hella loud. And dirt cheap. https://www.amazon.com/Broan-688-Ceiling-Plastic-Grille/dp/B00004TTZZ
The purpose of those lines is to create airflow to prevent carbon monoxide poisoning. They function passively, so you should uncap them, for safety sake (or at least make sure a COO monitor is installed... fuck, I don't have one installed....). Notice how one inlet is (or was, or should be) at eye level, and the other is near the floor? That is to make use of when heat rises, the air near the inlet of one will rise out, and the cold air near the bottom of the other will sink, starting a circulating flow. Yes, this chills the basement, but, if it's unfinished that's OK.
a 100k but furnace may use rpoportionatly more air for combustion, but its in a controled space and a very efficient combustion, while the 54K burner will disperse the COO along the heat current it creates meaning you need to remove much much more air to gather all the gasses you should, than with just a sealed vented furnace. Also, there is a difference between inline duct booster fans, which aid in airflow, but lack dynamic pressure, and turbine fans which are both consistant rate and high dynaic pressure (meaning it would be able to pull air from a further distance with less drop in CFM)
These http://www.amazon.com/LEDwholesalers-GYO2402-6-Inch-Hydroponic-Booster/dp/B003YFADW8 won't work,
you'll need this http://www.amazon.com/Active-Air-720-Inline-8-Inch/dp/B002JQ4K1I
or for a quieter operation with better dynamic pressure, this http://www.amazon.com/gp/product/B001I4DHJI/ref=pd_lpo_sbs_dp_ss_2?pf_rd_p=1944687782&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B004C2IWIE&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=1V2RCEEAMG31CYMSKC7B
I am not trying to be alarmist, but I know the math off the top of my head, because I've worked with it SOOOoo many times, and as they are for safety, I urge you to heed my warning.
Those fans are cheap junk. The whole unit costs $15. They are way too loud out of the box and barely move any air. https://www.amazon.com/Broan-688-Ceiling-Plastic-Grille/dp/B00004TTZZ/ref=sr_1_1?ie=UTF8&qid=1478483819&sr=8-1&keywords=broan+50+cfm
Yikes. I'm hearing fire hazard and too hot of a grow environment. I hope you can afford an $80 fan before you burn your house down or at the very minimum kill some plants. Edit, they are even cheaper , no excuses, sorry buddy
Agreed. That fan is never going to produce a negative pressure. Which means, OP, your tent is leaking air(scent).
My fan
Look into something like that.
I don't know very much about those booster fans. I have never used one but i have heard that they are not very powerful. I would try to get something like this one. The carbon filter you linked looks good though.
This is why I'd never buy a smaller fan. Not only do you have to make up the difference, but you have to do it in such a small area, which is even tougher. If it were several inches, you could slap up some new drywall scraps and then mud/paint. But 3/4", that's like doing drywall surgery. Pain in the butt.
If possible, I'd go up in size. Even if it's just 3/4" in the other direction, it's just cutting drywall. That's easy.
Check out the Panasonic Whisper line. I installed one in my basement bath and it's awesome.
EDIT: I see now you're saying the bezel does cover the hole. In that case, I wouldn't worry about it so much. You can probably stick some foam backer rod or other cheap weatherstripping in there. It's going to be hidden, anyway.
EDIT 2: Someone else rec'd expanding foam. Indeed, that's probably the most ideal solution. But I wonder whether you'll have anything to back it. I'm imagining a 3/4" gap between drywall and the fan enclosure, with literally nothing above. Just open air. So, if you spray foam up there, it's just going to fly up into the joist bay. I suppose maybe you could spray it directly on the side of the enclosure. If it sticks, you can build it up that way. Also, expanding foam can get VERY messy and it sticks to everything. Have water and maybe even acetone nearby for cleanup. Wear gloves. Good luck!
up to a good start...
If you dont use a carbon filter and you dont have a long run for the exhaust maybe this could be helpfull.
I used a 6'' vivosun inline booster fan for my 5x5 with a 400w hps and it sucked the air out quite fast, a bit noisy should be more than enough for any hps and was pretty cheap compare to the usual inline fan.
and you can buy a speed controller for cheap on amazon too because its almost pulling too much...
https://www.amazon.ca/VIVOSUN-Inline-Booster-Noise-Grounded/dp/B01C82SZRM/ref=pd_lpo_vtph_86_bs_t_1?_encoding=UTF8&refRID=93CSGQER4PC5V7Q26864&th=1
​
but if you plan on running long tubing for the exhaust or have 2 or 3 lights together get a bigger inline fan
https://www.amazon.com/Hurricane-Inline-Fan-Performance-Ventilation/dp/B006Z1JLN0
​
have an 8 inch (around 800cfm) for a 5 x 10 and with the filter and long ducting run and its borderline. If you have straight and short ducting... you can get away with a smaller fan . The filter will reduce the pull of the fan .
Based off of the quantity you have, IF you pipe them all together I would do at least an 8in for main ducting. You could connect 4” or even 6” to the main 8” or larger and then supplement the airflow with an in-line air duct fan. For ~$100 u can get an in-line fan that does 745CFM on an 8” duct. IF you are not connecting them all together and they are each separately exhausting, a 6in will be the minimum IMO.
Hurricane Inline Fan - 8 Inch | 745 CFM | High Performance, Commercial Grade Inline Fans, Quiet Operation - Ventilation Fan - ETL Listed https://www.amazon.com/dp/B006Z1JLN0/ref=cm_sw_r_cp_api_GC7QAbPKKCK20
Well.. If that's not working you should just buy the cheapest carbon filter + fan on amazon and be done with it IMO.
Although, even with a good filter and fan you have to have some negative pressure meaning that you have to suck out more air than you pull in. If you can't get negative pressure then the smell can leak out. If you have a tent and you get a real fan and filter you'll see the walls suck in when you close the tent and that means theirs negative pressure.
Here's some amazon links.

I remodeled my Master Bath. Used lots of tile. Bathroom felt cold. I installed: https://www.amazon.com/gp/product/B001CJUKZS/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1

Heats bathroom to "Toasty" in 10 minutes......................
That's an ongoing investigation on my end.
So far what I've discovered is that adsorbent technologies, carbon and otherwise, do work but with a number of caveats.
Here's some devices I've tested - with a high grade industrial PID meter directly on the output of the exhaust:

Limitations of carbon:
For instance carbon is not very effective (not totally ineffective) for formaldehyde.
Often times carbon is mixed with additives to breakdown VOCs that carbon has a hard time catching. That's true with the Austin Air, but these additives can break down faster than carbon.
The quickest most effective method to bring VOC levels down is to ventilate. Getting temps up and opening Windows and blowing air out of rooms/homes is the best method of all. Remember VOCs are liquids at ambient temperatures. What gets into the air are molecules that off gas from the liquids on surfaces. Just like taking a how shower creates more humidity.
All said, I would really, really like PCO/PECO technology to work. The concept is very attractive. Instead of trapping (carbon), or exhausting (ventilation) lets just destroy the VOCs by turning them into water and CO2. I was really disappointed when measurement with the Molecule were nil. I was expecting it to working judging by the 3rd party test that MoleKule funded. Problem is the environment the MoleKule was used in does not resemble what we find in our homes. That difference seems to be significant.
I haven't given up yet concerning the MoleKule or other PCO or plasma systems yet.
Finally keep in mind that the MoleKule might be very effective in killing biologicals. Not something I tested for.
Fellow Maine-ah here, just setup an 8 inch fan and it's almost overkill. https://www.amazon.com/gp/aw/d/B01CTM0LLO/
This is my first time growing, so please feel free to critique/rip into my setup, as I really appreciate all the help and knowledge! I actually ordered my seeds from JAHseeds a year ago, but never got my shit together enough to actually do anything with them.
 
I do want to take a quick moment to thank u/AFK_ing for the seeds first, as they were actually gifted to me for free. I placed an order on a whim one night, and then completely forgot about it. Turns out that JAHseeds never ended up depositing the interac transfer I sent them, so it inevitably expired. I had forgotten about the order completely, when out of the blue one day I received a letter in the mail complete with 12 free seeds and a handwritten 'apology' letter. This absolutely floored me, and left me feeling super warm and fuzzy inside. I've been cherishing the seeds up until now, so I'm really really happy that I can finally bring them to life :) Anyways....thank you JAHseeds!
 
Onto the setup! Currently running:
 
2x alibaba 240w QB
 
Promix HP + 2inch layer of worm castings on the bottom
 
Strain is The Best My seeds are not feminized however, so still unsure of sex.
 
Right now they are in 1 gallon pots and I'm planning on moving them into 7 gallon fabric pots when the time is right.
 
I kinda went ham one night and bought the entire GH nutrient lineup (including all the additives....) so I'm planning on sticking to their schedule (halved) throughout the grow. I know I could have done without a lot (most) of them, but yeah it was still cheaper than buying an Oz from the LP....Currently only feeding them water.
 
The tent is a GA 48x48x80, with a Vivosun 6 inch duct fan and carbon filter
 
Holmes Lil' Blizzard fan (this thing moves a lot of air)
 
I originally had a smaller tent so I started out germinating 3 seeds by dropping them in a glass of water for 36 hours. After they all popped, I planted them directly into coco pots. At that time I decided to change to a larger tent, so I dropped 2 more seeds into a glass of water to germinate. 36 hours later one of the seeds had popped, but not the other. I planted the one that popped, and left the other in the water for another 12 hours. At this time it still hadn't popped, so I just dropped it into a pot with the others. The one that never popped didnt end up coming through the soil until about 2 days ago (I was actually just about to give up on it). It's the tiny coco pot in the middle. Pretty sure it's gonna be a retard plant but whatever, I'll give it some love and care. Don't tell Justin. The nice healthy plant on the bottom right is the other seed that I germinated with it at the same time.

tl;dr i love you all
The only 260 cfm fans I can find are duct boosters. Do you have something like this
Most tents have an exhaust port to accommodate an inline fan. You can purchase an entire light kit for less than $200 on ebay. You then purchase an exhaust fan and hook it up to the light. It will work fine.
For example only: https://www.amazon.com/Yield-Lab-400w-Cool-Light/dp/B00FICG3EW/ref=sr_1_8?ie=UTF8&qid=1511594848&sr=8-8&keywords=400w+light+kit
For example only: https://www.amazon.com/Apollo-Horticulture-Variable-Controller-Ventilation/dp/B01C6IJSB0/ref=sr_1_19?s=lawn-garden&ie=UTF8&qid=1511594905&sr=1-19&keywords=inline+fan
You can instead stuff a cooler 4x2ft T5Ho in there: https://www.growlights.ca/growlights/t5-ho-grow-lights/2-foot-24w-t5-ho/fusion-bright-2x8-192w-t5-ho-kit.html
You can get many other models; I only posted quick shots. The T5HO kit would be a good bet for what you want. No need to exhaust and you could bring the light closer to the plants (like really close). With the HID light, you don't get so much play with height and would have to keep the light farther.
Its not really the heat problem; you will need the height for growing plants.
1 plant per pot. I'd go 3 gallon pots. Smart pots are great and harder to fuck up.
165 Cfm 4 inch fan would work well. I use that in my 4x2.
Edit. This fan. http://www.amazon.com/Active-Air-inch-Line-Fan/dp/B002JQ4N92
Edit edit. That light is only 200 true watts. You need around 400 watts for 8 square feet. You tent is 4x2 and that light is good for 2.5x2.5. I'd look into a 400 hps/mh combo.
Probably not. What kind of fan is it? Moving air through a filter is very difficult unless the fan is designed for that purpose.
This would probably work, but this would definitely not. Even though it has more CFM. I made this mistake a while ago, and wasted money I could have spent elsewhere.
>There is no such thing as a humidity sensing fan
This statement is false
Take this note with caution, as you can damage yoru system. Go to a cold room, or one that you dont use much (but not both) and try taping a piece of paper over the return, or half of the return in that room. This will prevent your system from getting air from that room, and in turn will suck out more air from other rooms, such as your warm rooms. The caution is that you cannot starve your system for air, and if you block too much you will starve it, and cause some issue or damage to your system.
Also, can try to add a register booster to your bedroom to see if that helps. Somethign like one of these.
https://www.amazon.com/Suncourt-Equalizer-EQ2-Heating-Conditioning/dp/B0007N5LHW/ref=sr_1_4?ie=UTF8&qid=1497371084&sr=8-4&keywords=register+booster
https://www.amazon.com/Suncourt-HC500-B-Flush-Register-Booster/dp/B0170UQHWM/ref=sr_1_1?ie=UTF8&qid=1497371084&sr=8-1&keywords=register+booster
And one last note, before you block anythign with paper, go to every return, adn put up a piece of paper while the fan is on. See if they all have no suction, tons of suction, etc. Can they all hold the piece of paper up? This can give you some clues.
See if this link works: https://www.amazon.com/Active-Air-inch-Line-Fan/dp/B002JQ4N92.
Also, definitely get a fan speed controller and set that baby at the lowest setting. These guys can really go and you're not gonna need all of that CFM for such a little tent. The key is that these fans can create higher pressure (to overcome the resistance of the filters) at lower CFM (to not turn the whole room/closet into a wind tunnel).
If you then hook up the fan to a temperature switch it'll only run when the tent gets hot enough. This will save energy, create less noise, and also avoid creating temps that are too low at night if you like your apt to be cooler while you sleep.
This is all way more info than you asked for but it'll be a really nice, easy system and it'll work with any size tent if you decide to go bigger in the future.
Panasonic makes some reliable and very quiet bath fans. I put one with a motion sensor in my first bath and a heater/ fan combo in my master bath with a countdown timer switch. I bought them on Amazon.
I've had good luck with this one
Should be plenty of CMF for a grow tent that size. Plus it has a built in controller so you can turn it down if needed. It pulls around 130w at full blast and 100 at min setting.
You need to do some math to figure out the temperate that all those watts would be giving off.
Once you have that temperature, you then are going to need to figure out how many times you need to replace the air in the tent via your output fans.
For making this easy I think you should just be concerened about the output fans and let the intake be passive through the grow texts vent holes.
For instance a 4x4x7 tent has 112 cubic feet.
The measurement of exhaust (output) fans are in cfm. ( cubic feet per minute ).
So if you were to get this fan. Which is rated for 740 cfm.
Hurricane Inline Fan - 8 Inch | 745 CFM | High Performance, Commercial Grade Inline Fans, Quiet Operation - Ventilation Fan - ETL Listed https://www.amazon.com/dp/B006Z1JLN0/ref=cm_sw_r_cp_api_wrPSAbZ1FFYQK
And do some quick math.
740 x 60mins = 44,400 cubic feet of air moves per hour.
44400 / volume of room (112) = 396.5 times within that hour, that the grow room air is sucked out through the attic - and intaking the air in the room passively.
An important part to this scenario is that the air needs to be completely vented outside of the room.
This also assumes that you have this fan on at all times, and at full speed. These types of fans comes with fan controllers to lower cfms. You can also put a timer on the power to the fan to control how often you need it on.
Your solution to getting the heat out of the room lies within this information I’ve shared with you.
Also - all these calculations are rated for 8inch ducting. If you lower the width of your ducting, it can’t move as much air and all your calculations need to be factored by that.
Well, my grow is a LOT larger than a closet but the principal is the same.
I have a bigass inline fan that sucks the air from inside the room out into my attic and the carbon filter is attached in the attic.
So basically I am sucking the smell out of the room, thru the carbon filter and out into the attic.
This creates a negative pressure in the room so the smell actually gets sucked BACK INTO the room. You can stand at the door to my grow and not smell a thing.
Your setup should be similar, just with much smaller parts
Use this or maybe this to seal up your windows. Use it like your life depends on it, because if you miss a little bit, the draft that gets through will inflate your shrink film and either pop it if it's forceful enough, or just circulate cold air in and out like a bellows. Then shrink film them. Shrink film needs to be less than 1" from the glass to retain it's insulative properties, any further out and it just becomes a wind break only. The exception is if you have metal framed windows, don't let the film touch those because the cold will conduct through and you'll have ice form on the inside. This year I'm getting an outdoor shrink film kit and filming them from the outside as well, so when the wind blows it blows the film against the window rather than inflating into my room. I don't know how it'll work out. I also ended up shrink filming that bathroom vent, probably not a good idea because of mold, but the window film pulls all the moisture out of the air and dumps it on my carpet anyway and my apartment was >10% humidity all winter while using a humidifier to put a gallon of water in the air per day day. Run a humidifier, humidity raises the heat index, so a 45F living room will feel like a 48F living room.
Put some of this stuff between the window when you close it, and do the same for doorway seals. Draft blowing in somewhere is positive pressure, which means somewhere warm air is getting blown out to compensate. For me it was the front door. I found this out because during a particularly bad wind storm I thought there was a dog howling in the hallway, but almost couldn't get my door open to check. It was my door howling and the pressure holding it closed.
Take the covers off of any outer wall electrical outlets and seal them up with this or probably just as well use that weather tape I linked before. If you live attached to other units, while you've got them opened up, sprinkle some of this in there. Your asshole neighbors are going to get bedbugs and send them over via the electrical sockets.
Lastly, depending on the layout and heating system of your place, there are these if you need them. But they're loud enough to make it hard to sleep if they're in a bedroom.
But mostly, fuck landlords that get to use our rent checks to pay their heating bills while I shiver like a god damn homeless man that pays $700 a month for the privilege.
I can't speak to how this compares to LED as I'm on my first grow and have never used LEDs but I'm using this light at 75% in a 4x2x5 tent with this fan/filter combo. Currently in flower and the temps have never gone above 82. Hope this helps.
Here is what I used. 2 wire shelves. 1 shelf holds 4x 8 card rigs (last rig sits in the front 'exhaust' area on top of a normal PC box). 1 shelf holds the fans that blow on the rigs. Air is blown over the rigs and to the front of the tent, and exhaust fans placed in that area for exhaust.

Ok how about this one? I could get two if needed and still be around 100 bucks with this grow tent. Then I just need the light and I'm golden. Actually won't even really need the light until I'm ready to flower, as I think I have enough light power now for a solid veg.
Close most, but not all of your downstairs vents in the summer. Run your furnace fan all the time, or buy a thermostat that has a circulate setting. Lastly if you feel you aren't getting airflow to upstairs vents they sell in line fans or ones that go over vents as a booster. https://www.amazon.com/dp/B0007N5LHW/ref=cm_sw_r_cp_apa_MGq5xbWVB3PE8
Something like this?
It would be alot cheaper and move 20x the air if you'd bolt one of these upside down on the top of the case and pipe it out, but 50 cfm is going to be loud as hell.
I'm pretty happy with mine but I think I'm going to build a much bigger one for next year. I've already got a big crazy fan on it ( http://www.amazon.com/Rule-240-Marine-Blower-4-Inch/dp/B000O8D0IC ), and I think more airspace inside the cooler would help
I appreciate your input, I will be making some changes soon. Trying to keep it easy on the wallet, do you think a 240CFM fan would work for cooling the bulb?
Yeah, most 120mm pc fans don't have enough static pressure to run any significant amount of air through a carbon filter. CFM doesn't mean much unless you have static pressure behind it to back it up. You could either opt for an inline fan like this for about $70 which would be more than enough for your setup, or you could try subbing out your pc fans for a couple of these bad boys which run ~$15 apiece but offer an impressive 133 CFM while offering higher static pressure ratings than any other 120mm pc fans I've seen with the same price/dB rating.
I have one of these Equalizer eq2 things which is about $35 at home depot. helps out, but a little loud. I think there are better ones on the market.
You need an activated charcoal filter. I have one for my shop that I use for VOC (fumes).
Put the charcoal filter where everyone is. Put the fan as far away as you can with the ducting. Dirty air gets pulled to the back of the room/building blown through the duct out the charcoal filter. You set up a natural breeze.
Warning: Buying any of these products will make Amazon think you are grower of ... other things.
So that isn't an inline fan, that is known as a duct booster. It's just meant to help keep air moving through ducts. You'll need a real inline fan with speed controller. http://www.amazon.com/Apollo-Horticulture-Inline-Variable-Controller/dp/B019INGAO4/ref=sr_1_3?ie=UTF8&qid=1464883260&sr=8-3&keywords=4+inch+inline+fan

The TDS I've been keeping at 200 with RO water + flora grow tri series + hydroguard + calmagic. Running 2 5000k CFL only 56 actual watts 200 equivalent 18 on 6 off.
That fan is fine. When someone says booster fan they usually mean one like this
https://www.amazon.com/VIVOSUN-Inline-Booster-Noise-Grounded/dp/B01C82SZRM/ref=sr_1_3?ie=UTF8&qid=1536626599&sr=8-3&keywords=booster+fan&dpID=517UzZcgrEL&preST=_SY300_QL70_&dpSrc=srch
You can get pens for cheap. $15 or so on amazon. You have to calibrate these more often than one of the more expensive ones like bluelab but other than that they work fine.
I would get a 600w HPS cool tube . Affordable and can't argue with their results. You will need to get an inline fan (duct booster) to go with it, also cheap on amazon. Just my opinion. A little over your 200$ but uoi could also go down to the 400w HPS. But for the 600w, to go over your budget by 40-50$ will reward you well. I also do understand that these are not as efficient, but its like only $30/month to run a 600HPS.
​
The low end LEDs will give you good results as well (if used properly) but I don't feel you will ever get the results you would using HPS.
​
Just my opinion.
They're not very attractive but you could try a register booster fan: https://www.amazon.com/dp/B0792QR5YT/
Couple things you will want...
This is the fan I use, I just used 6 inch ducting out to a dryer vent. https://www.amazon.com/VIVOSUN-Inline-Blower-Ventilation-Certified/dp/B077492C4C/ref=sr_1_1_sspa?s=hi&ie=UTF8&qid=1539720436&sr=1-1-spons&keywords=vivosun+6+inch+fan&psc=1
And the brew bag is very heavy, I use these with a bicycle hook to hoist the bag.
https://www.amazon.com/gp/product/B077BKWZTH/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
I have had a couple succesful runs with the system, all in all it is worth it since I live in NorthEast Pennsylvania where it gets really cold outside during the winter. No more brewing outdoors. I also use a Gigawort from Northern Brewer (I know the hate) to make small batches as my test system.
​
Here is an easy fix especially if it’s just one room. https://smile.amazon.com/AC-Infinity-Register-Thermostat-Control/dp/B0792QR5YT/ref=sr_1_4?ie=UTF8&qid=1542207039&sr=8-4&keywords=vent+fans+booster&dpID=41CSIeq4GYL&preST=_SY300_QL70_&dpSrc=srch
I was looking at this one. One that you wire in to the bathroom of a house. Figured since I was planning on forcing air through a filter, overshooting the CFPM's would be a good idea, even though it will be a pretty small area.
Similar issue and the solution was to replace the exhaust fan with a Panasonic with built in motion and humidity sensing capabilities. Panasonic built a smart thing.
Sure, here's a 6" Vivosun blower for $55. Here's one with a carbon filter and speed controller included for $119. There are higher quality blowers available, but these ones are pretty good for the price point.
I was eyeing [this fan myself.](https://www.amazon.com/Apollo-Horticulture-Variable-Controller-Ventilation/dp/B01C6IJSB0/ref=sr_1_3?ie=UTF8&qid=1491129860&sr=8-3&keywords=4%22+inline+fan+with+controller
I was eye)
It has the speed controller built in, then you'd just need to pair it with a carbon filter.
Id spend a little extra and get a 3x3 tent so you can fit the light in there. Id get a 600w fixture with both metal halide and HPS usable. Metal halide for veg, HPS for flower. The more light, the bigger the yield. Idk if you want 2 fans, one for the light only and then one for tent air exchange, but if you just want one fan which I imagine you do since you are trying to keep costs down, if you have two fans, then youd need two filters. Id get a bigger CFM 450 with adjustable speed, incase 450 is too much. This is what I have in my 4x4 with a 1000w, https://www.amazon.com/Apollo-Horticulture-Inline-Variable-Controller/dp/B019INGAF8, probably be perfect if you only want 1 fan in a 3x3 600w.
Oh and just saw the tent you posted, its only 4 feet tall, get one that is at least 6 ft.
Nice! You won’t be disappointed. Good luck!!!
Just an FYI - it looks like the 135 is a lit you have to assemble and the actual light board is the same wattage as the 100. Either way you’ll be happy.
The HLG 100 was fully assembled:
https://www.amazon.com/Horticulture-Lighting-Group-High-Efficiency-Upgraded/dp/B07C59J8L2
Last bit of advice - if you’re going to get a exhaust fan don’t get the Vivosun. I love their tent but the fan started making horrible noise after 17 days. They were cool about the refund but I went with:
https://www.amazon.com/gp/aw/d/B002JQ4N92?psc=1&ref=ppx_pop_mob_b_asin_title
It’s not a variable speed though but at least it’s an even sound. Like a window AC unit. Maybe a bit louder.

I bought one of these for exhaust of my 7 GPU rig and I highly recommend it. Active Air 720 CFM Inline Fan, 8-Inch https://www.amazon.com/dp/B002JQ4K1I/ref=cm_sw_r_cp_apip_Nx8lUuqP8GAKB It’s been running about 6 weeks now and does a great job of pulling the hot air out of my storage room and some “cooler” air in through my louvered door. I tried a small room A/C but this is a much better solution - it vents up to my attic and out my ridge vent. I built an exhaust manifold with 3”x12” ductwork with (14) 2” diameter holes in it which gets the exhaust closer to the output of each gpu in the rig. Will post some pics.

A fellow grower on here got the 4 inch and said it was quiet and light.
I understand being overwhelmed at first here, but I couldn't imagine trying to figure it out from a different language, so props to you! You can definitely build your own setup, or you could purchase a grow tent. The sizes range anywhere from 4x4x7' (or 4 feet by 4 feet wide and 7 feet tall), smaller, bigger, there's something out there for everyone. Some common lighting sizes with MH/HID (metal-halide/high intensity discharge, just different styles for different stages) bulbs are 400W, 600W, 1000W or so I've seen on here. You could also go with LED lights, but I don't know much about those. It depends on how many plants you'd like to grow and the size of your space.
As far as fans, I would get more powerful inline fans like this or this to actually move the air around if you're planning a bigger grow. If you're not too worried about a carbon filter, which it never hurts to be, maybe you could try making a DIY one with some supplies from your store and a guide from this sub?
Hope this helped, best of luck and please update us! (ps your English is actually fine and easy to understand)
Check your furnace filters - dirty filters will reduce airflow.
Try a vent booster fan.
This one? http://www.amazon.com/Rule-240-Marine-Blower-4-Inch/dp/B000O8D0IC
Im not really a fan expert, but I still think that company is making up bullshit numbers for their filters CFM ratings.
Heres what I went with - Fan, Speed Controller, Carbon Filter
Wow for the LED, I will definitively look into LEDs if I decide to upgrade my old 400W HPS.
As for the fan, if it's anything like this type of duct fan, it won't work with the filter.
This is the kind of fan you need
You could probably yield about 3oz on your first grow. Far more if you fine tune and get some experience.
You'd need about 600 watts of light. at $.12/kwh, thats an extra $30/month on the electric bill. Not too noticeable. You'll also want a 6" carbon scrubber to leave room to grow. see what I did there?
I suggest you look up how to scrog, its very easy.
Will you be doing hydro or soil?
I was expecting something that used as much power as this https://www.amazon.com/dp/B001CJUKZS which would need it's own circuit.
275W is small, less than three amps and could definitely share a circuit, I'm just not understanding how that will generate enough heat, quickly enough to be useful.
I assumed you had a good inline fan for exhaust, as they’re necessary to help keep humidity down in late flower (or you risk mold). You can get away with passive intake (no fan, just a hole), but you’ll need a good exhaust fan.
You can do it on Amazon for ~$80, and the $45 fan should last you many grows. I recommend this 4" inline fan since it comes with a speed controller, and something like this filter, since it's cheap but will actually get rid of smells for a couple grows.
i'm looking at this one:
http://www.amazon.com/dp/B005XNNYMU/ref=wl_it_dp_o_pC_nS_ttl
and:
http://www.amazon.com/Active-Air-720-Inline-8-Inch/dp/B002JQ4K1I/
would these be considered good quality? or do i need to spend roughly twice as much?
thanks for the info.
I owned a bar with three smoke eaters back in the day. The maintenance is horrible and dust will make it spark/snap.
If you have space above, below or to the side of your space, this is what you want, on a switch. Other brands are too loud, and if you can't run a 6" duct, get a lower CFM unit.
The SmartPot is too large, particluarly if you are growing hydroponically. If you are growing in soil a 3 gallon container about 75% full provides a wide base that will dry out evenly. Hydro, 1-2 gallon container is appropriate for the space.
Heat management is important. Indoor gardening is 90% environment care and 10% plant care. An exhaust fan will make a difference. I find that axial (computer) fans make a ton of noise for the air they are moving. They are also a little dangerous. My 5" axial has nearly taken off a finger nail more than once. While more expensive and larger, inline fans handle the negative pressure and muffle the sound better. Bathroom exhaust fans aren't bad if you can do a little electrical. Check out this one: Broan 688 Ceiling and Wall Mount Fan, 50 CFM 4.0 Sones, White Plastic Grille https://www.amazon.com/dp/B00004TTZZ/ref=cm_sw_r_cp_apa_i_YZcdBbKV43YMA
We dealt with this for years until recently replacing our HVAC system with mini-splits. On a hot 100-degree day, set the thermostat to 72, and if we're lucky it's only 85 upstairs. Our problem was just a poorly designed system with very low vent pressure upstairs.
We tried booster fans like this for awhile, they did make it better but it just wasn't enough. And they're kinda noisy.
Eventually we gave in and bought window units for the bedrooms upstairs, one 8000BTU and one 6000BTU. Honestly our electric bill was so high in the summer due to the central AC, I hardly noticed the increase from the window units, maybe $30/month. It was well worth it for the increase in comfort, the only downside is the additional noise.
You could do the bath fan idea but with a much more powerful fan. Something like this that vents from the top floor to the outside, in combination with some opened windows, would probably help quite a bit -- as long as there is cool (and not too humid for your tastes) night time air available, and you don't mind leaving windows open for hours. But it's kind of a hack, and if you could tweak your existing ducts to work better, that would be more ideal and wouldn't require messing with windows and whatnot every night.
I bought a $15 replacement fan. This one: https://www.amazon.com/gp/product/B00839MJPE/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 I am going to install it tomorrow and pray to the 3D printing gods that it does something to quiet this thing down. If it doesn't work, I will 100% try the piece of paper. I am really disappointed the dampers didn't do the trick. Thanks a lot for your responses btw, I really appreciate it.
https://www.amazon.com/gp/aw/d/B000O8D0IC?fp=1&pc_redir=T1
This is what I use. Can't really say it is good or bad since I don't have anything else to compare it to. It does suck up most of the fumes but not 100%. Some always escapes when I open the lid.
I keep the original fan just for the housing and easier hookup to the 4" vent hose.
Don't use a rangehood. Use a bathroom fan. Something like this:

I am working on adding a little brewery to my basement. I will convert a propane burner to use natural gas.
Its easiest to just replace the burner itself. But I believe you can also just modify the inlets also. https://www.youtube.com/watch?v=0DD9dhluz3Q
I also got a marine blower from amazon, should handle the steam and moves 235 CFM. https://www.amazon.com/gp/product/B000O8D0IC/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
This is what I used:
I did not change out my part cooling fan, but that's up next on my list to do. The stock one is not very loud anyways, so I'm in no rush.
Be careful if you do the Power Supply fan. It's plug and play since the PSU already uses a JST plug, just be sure that you're completely unplugged, grounded, and don't go poking at components in there in case a capacitor has retained charge or something.
I watched this video to get a general idea of what to expect before diving in and replacing things. This guy goes through the extra steps of installing JST plugs for all the fans, whereas I personally just direct-soldered mine. Up to you on which approach you take.

Noiseblocker NB-BlackSilent. There are 3 fans to replace, not including the one in the power supply. The servers are very silent now.
You'll end up taking 1 of the 2 brackets per fan out, which will leave 2 small empty screw holes in the chassis. If you're paranoid you can buy adhesive screw hole covers, or just use some electric tape.
Be warned that I have not done any sort of stress testing on these fans to see if there are any heating issues. I haven't had any yet though, and they were recommended by someone who said they didn't have any either.
I went with a 60W eBay chinese special like this is a nice starting option because it does include absolutely everything you need (except a water reservoir, I use a Coleman cooler) at a reasonable price. You can get it delivered to your doorstep and stay within your $2500 budget.
That being said, there were several initial pitfalls (like blowing fuses and melting switches) that were caused by some exceedingly poor documentation (and a little laser cutting inexperience on my part.) Once I worked out those initial problems, its been cutting reliably for us for the last 6 months with almost daily usage.
The only real upgrades we've done have been a water cooler (we grabbed a water refigeration unit for a large aquarium for $275) and an upgraded exhaust fan (the included unit was very loud).
Next on the list would be an adjustable air assist with a more consistent flow, but what the included air pump is works well enough.
Ventech is cheaper and better quality.

You do not need a fan that crazy. Get a six inch inline duct fan. That will do the job
It's cheap junk. Ditch it. Get a Panasonic heater/fan. You will not look back...........
