Reddit reviews Phresh HGC701005 Carbon Filte For The Cleanest Air Around 6" x 16" - 400 CFM, Silver

First grow.

This took 2-3 months. Seems like I ran into a number of first-timer pitfalls along the way. Good learning experience though.

Can't wait. So god damn tired of shady, undependable hook ups.

  Edit 1:
  
  Some have asked about my setup. This is about everything. This is my first grow so take my suggestions with a cup of salt but this stuff has worked well for me.
  
  Tent:
  
  Zero complains. Very happy with this. It just fits perfectly into a closet (had to remove the hanger bar though).

  Carbon filter:
  
  The inside of my tent stinks. I smell absolutely nothing outside. Don't get caught. Get a good carbon filter. Maybe not this one, but something.

  Inline fan:
  
  I hand this outside the tent. No need to take up any space or add any heat inside the tent.

  Variable xformer for fan control:
  
  This allows me to control the noise and airflow. Every other fan controller made the fan buzz. This thing is quality built. I keep it around 50v.

  Check valves:
  
  You NEED these. Many airlines are thin enough that if the power goes out or a hose becomes disconnected, capillary action might permit water to back-flow into your electrical air pump and/or just flood your room. Don't take chances when a .50 cent valve will protect you. There are some horror stories in the aquarium hobby about this. Note, even if the air pump is higher than your res, capillary action can pull the water up through the air hose. This is the same principle that allows 100ft trees carry water from the roots to the canopy.

  Lighting
  
  
  
  Lights:
  
  Word of warning. Start off a good distance between the lights and your canopy. These product more light than you think and I have burned and cooked plants from keeping these too close. They don't product a ton of heat or anything. I think it's just too much light if they aren't a good foot or so away from the canopy. I assumed I could practically lay LEDs on top of my canopy. Not so.

  Nutes/Water changes
  
  
  
  
  Pond pump:
  
  This is another must have! I've been using these for a while now to handle water changes in my aquariums. It's also awesome for mixing nutes before they go into your DWC. I drop one in a bucket without a hose attached and then just dump all my nutes and such in. The pump does all the mixing. Then I adjust the pH a little. Give the pump about 10-20 seconds to mix my pH up or down in and test again. I don't have to worry my pH adjustment isn't probably mixed yet. I makes the mixing process so easy and fast. I also use these to pump out my res once the scrog screen is in place.

I use a 4x8 inch one of these it is made for growing, and I just hooked a duct fan from Menards to the end of it and leave it laying on its side under the desk plugged in 24/7. I can leave ground up bud on the desk, I keep all my vapes in the room, and I can vape excessively all day long in my room, and the smell still doesn't leave the room :) (Even in the room the smell is VERY muted compared to normal)

I would really suggest you get a Carbon filter, that is the only thing that truly works well imo

Personal experience here -- the iPower 4 inch filter / inline fan combo didn't work very well at all for me. My entire garage smelled like herb.


What I have now, although was a bit more pricey:


Phresh 701005 Carbon Air Filter, 6 by 16-Inch, 400 CFM


Vortex 347 CFM S Line S-600 Fan, 6"


iPower 6 Inch 25 Feet Non-Insulated Flex Air Aluminum Ducting Dryer Vent Hose for HVAC Ventilation, 2 Clamps included


CARTMAN 1" x 12' Lashing Straps up to 600lbs, 6pk in Carry Bag


 


Here's how it looks:

You're going to want to use the same setup that is used in growing. Get a carbon duct filter, an inline duct fan, and some ducting and set that up where you are growing. These are actually carbon pellets instead of a carbon mat like in consumer air filters.

[Filter](https://www.amazon.com/Phresh-701005-Carbon-Filter-16-
Inch/dp/B004FVJK60/ref=sr_1_1?ie=UTF8&qid=1468221153&sr=8-1&keywords=phresh+filter)

Inline Duct Fan

You don't even need ducting if you don't want it, you can literally mount the two of them together. I place the unit on a raised platform (like a table or something) for better circulation. That setup right there will change the air completely in a room that size once every 4 minutes.

Yep that is the fan, and for the filter here is the 6x16" one.

What lights are you using?

If it's current-gen LED, you should be fine with a 4" inline, and 4" Phresh filter. If not, 6" inline and one of these.

I don't know that it's the best "bang for your buck". But cheap fans and cheap filters, are, well, cheap. Fan is the most important part of your grow. If your fan goes, your plants die in hours. Filters, IME, either do an okayish job for a cycle or two (Vivosun, Apollo, iPower), or they do a great job for 1+ years (Phresh).

That reflector may be a little difficult to get a 4 foot light footprint from 2 feet or so (you need to measure the footprint from where the plants leaves will be not the bottom of the tent). You may only have 4 square feet of good light coverage with a short tent.

One nice aspect of a taller tent is you can always lower the light.

From what I've seen, people usually use T5 bulbs in the shorter tents which are often just used for mothers or new clone establishment.

Multiple strains are tricky, you'll have varying plant heights to deal with so splitting the difference between what's the ideal light distance per strain is something you'll be monitoring often.

I say get a 60" tall tent and enjoy the freedom you'll have if you ever decide to grow a nice tall sativa. Plus you can always put the pots on overturned 5 gallon buckets to save you back.

What you said about 8 plants is interesting. That's pretty closely packed pots. You'll have to make sure no plant is wider than 12" or it will be shading the plant next to it. Plus growing plants against the side of the tent isn't great for them. They usually end up looking crappy. If you're trying to grow small plants I recommend smaller pots. 3 gallons are fine. You may be limited to 6 plants in a 48x24 space fitting comfortably.

But that's just my 2 cents. I say leave yourself with as many options as possible. Future you may want to be doing something very differently.

As far as carbon filters go, you've got a 347 cfm fan so you're limited by how many CFM the filter will support.
I'd say

is a good one for that even though it's rated for 400 cfm. Phresh is very well respected and should keep all the smells under control.

Is this it? https://www.amazon.com/Phresh-701005-Carbon-Filter-16-Inch/dp/B004FVJK60/ref=sr_1_3?ie=UTF8&qid=1519402929&sr=8-3&keywords=Phresh+filter&dpID=51xtbdlDtsL&preST=_SY300_QL70_&dpSrc=srch

This is what I have. Works great. The variac does not hum at all. I have the vortex as well.
