(Part 3) Top products from r/Autoflowers

Introduction

setup: - 80x80x180 tent - 600W Viparspectre - carbonfilter etc ;) - medium: coco perlite 70/30 - temp: around 18.5°C-22°C - rh: 50-70% - containers: 1 11l Liter plastic pot, 3 5-Gal/ 20l smart pots with about 15l medium - PH: 5.6 - ppm: about 650

So we are now entering week 5 i guess? Around 50 days. As u can see i had some major height problems but some late lst helps out a bit.
I also repositioned the carbon filter to the right so i can put that light higher. It is now not perfectly centered but i tilt it until the light spreads evenly.
I am sorry for some low quality photos but it gets hot and humid pretty fast in my room. But now let’s get to the babies

Problems:

Purple:
Was stunted pretty early and is super skinny now. She is also loosing some lower leaves but bud is developing pretty good for her overall health. She doesn’t look that good to me.

WhiteWiddow:
Well thought she would be way faster, like she was in the beginning. Now she ist he slowest? Not super happy about her but i increased her height using some books so she gets some light atleast. She is sitting in the right back so it’s totally crap with the light setup atm. Still having awesome stems and guess i can just put her under the main light when the first one gets chopped.

Moby Dick: A fucking monster now. So many budsites and leaves. She is pretty healthy but also loosing some leaves in the bottom. No LST needed for her she is spacing her colas up pretty good and i just let her go.

Critical: wow…awesome plant. She just exploded in height but some light lst to the main colas did an awesome job. I really like the way she grows now.

Questions

Overall they are pretty healthy, but i am not sure where to locate the problem of my girls.
I thought yellowing of the leaves would come from not enough nitrogen? But there are also some slight signs of nute burn i guess?
I didn’t increase my nutrients, just shifted the amount of bloom and gro. So i would get more nitrogen.

Also they start to drink fast i now consider buying a small watering system. But for now just have to adjust the watering table.

My Humidity is always pretty high(40-70%) while the temps are between 18.5 and 22C. I am concerned about but rot and other bad stuff so i defoliated them a bit. Well this didn’t change that much so i am not thinking about buying a small dehumidifier.
Or do u guys think i am fine since i added a second clip fan?



If u made that far thank u very much! I would love to spend more time with my plants but university :/
I would love to hear some insights of you and maybe u can confirm my nitrogen deficiency or nute burn :D

Have an awesome day guys :)

Tools required:

• 10 mm wrench
  
• 13 mm wrench
  
• Phillips head screwdriver
  
• 3/8" or 1/2" drill bit
  
  Parts required:
  
  
• Cheap RO/DI
  
  
• Saddle Valve
  
  
• Push Connect Shutoff Valve
  
  
• Total cost: ~$80
  
  Process:
  
  
• Follow the instructions for installing your saddle valve to a cold water pipe, with enough 1/4" vinyl tubing connected to reach through your wall. It's most convenient to do this directly behind your bathroom faucet, if you have access to those pipes. You will be using your phillips head screwdriver, 10 mm wrench, and 13 mm wrench for this process. Make sure all your nuts are secure, but don't hulk out on them - remember that brass is not vibranium - you CAN strip it if you go too hard. Leak test, and flow test at this point. Once you're free of leaks, and have good flow to your vinyl tubing, completely close the needle valve on your saddle valve to cut off flow.
  
  
• Drill a hole through your drywall above your sink. Pass your 1/4" vinyl through the wall. Push connect your shutoff valve on this side, and connect another length of vinyl tubing to the other side of the shutoff. Close the shutoff valve. Go back and completely open the needle valve on your saddle valve, to allow flow to the the vinyl tubing. Open your shutoff valve to again ensure that you're getting pressurized flow through your vinyl tubing.
  
  
• Drill 3 holes in the side of your undersink cabinet, preferably right next to your bathtub (as shown in the last video of the OP gallery). 1 hole will route your supply line (from the shutoff valve) into the cabinet, to supply tap water to your filter. The other two, respectively, will run your waste and product lines out of the cabinet.
  
  
• Run your lines and dry fit the mount of your filter inside the cabinet. Using the 2 phillips screws provided with the filter assembly, mount the 2 brackets connected to the RO membrane housing, directly to the wall of your cabinet.
  
  
• Total installation time: ~30 minutes
  
  Now you have a clean water supply in a hassle-free implementation. When you're ready to make water, just snake your waste line securely down the bathtub drain, open the shutoff valve, give the filter a few minutes to push water through the system and flush, and make water. Easy breezy beautiful cover girl.
  
  If you don't have access to be able to do this in your bathroom, the same setup can be performed anywhere you have access to a fresh cold water pipe and a drain line.

Thanks for the replies, man, super appreciative.
I haven't dropped anything into lights yet, trying to complete my research before getting anything, so I don't slap myself in the head later.

With the light you posted:

1. Does it move up and down easily? Or should I not be doing that?
   
2. Do I need to get a different bulb for the flowering stage?
   
   Also, in terms of cooling and keeping temps low, Would I need a separate exhaust fan, as well?
   I'm sure it's easier to explain by me actually seeing it as opposed to trying to imagine, I just can't quite grasp it.
   
   Also, with that ventech fan, is it easy to attach some form of carbon scrubber? Has to be ~somewhat concealable, for the random inspection here and there.
   
   edit:: found this: what you're talking about?

   I'm really hoping I'm allowed to link here. Will remove if I need tooo.

It depends on a lot of things. Depending on your light, it may be simpler to get a cheap lux meter (I have this one) and measure. I was pretty surprised by how much of a difference it made being at slightly different angles from the light, but otherwise the same distance. Also, check what your light manufacturer recommends. (You didn't say what kind of light you're using.)

Before I got the meter, I just kept it at 18-20" away, which may have been a bit too far -- since, I've adjusted things once a week or so, based on actual measurements. Of the two plants, one is a couple inches taller than the other, so I've trained it to bend the top colas away from the light a bit. (Some got too close and started to burn.) I'd also prefer to dim the light, rather than running it at max power but further away.

Note that a lux meter won't be very accurate with a blurple (blue/purple wavelength) light, but they should work well with QBs and COBs.

This is what I use: https://www.amazon.com/dp/B00132G102/

Get a big bottle of the General Hydroponics pH 7.0 calibration and storage solution. You need to rinse the electrode with clean water after every use and change the storage solution regularly (1-2 weeks), but if you keep up with the maintenance they'll stay accurate and last quite awhile.

Those drops suck IMO, same with the strips. I feel that the nutrient ions somehow interfere with the reaction on the strips, and you get color interference like you said with the drops. A glass electrode pH meter is what you want.

Proper pH is fundamental to the plant thriving just like light, temperature, humidity, etc. because it's so closely tied to root health and nutrient absorption. It's worth paying close attention to.

I like Silica Blast on Amazon. I've used it for multiple grows now and it's only helped. Makes the leaves stand up really straight I find which is always good when you're trying to maximize how much light gets to all the leaves.

Check out garden velcro. I use it for my girls in smart pots. It grips the fabric perfectly for LST.

i replaced the stock pc fan with one of these... almost COMPLETELY silent.

the phresh duct silencer is also a great way to reduce the sound.

Purchased these on Amazon for about $9

One filter is not quite big enough to cover the entire intake, but two are more than enough. They stick right do the Velcro, and although they don't block 100% of the light they do a far better job than nothing.

That's kind of high. Do you have intake and exhaust fans set up? If you already do, I'd consider a supplement to help it do better in higher temperature.

I got a few paint trays that I have some cooling racks like these resting on.

The water just drips down into the tray, comes towards my tent door, and I vacuum it out with a little wet/dry vac.

You can't overwater. Don't use too much perlite in the coco mix or you may have to water multiple times a day(I mixed nutes once a day). I just got a blumats drip kit because I was getting tired of mixing nutes and watering nonstop.

You'll be able to tell if it needs it based on look/weight/feel soon enough. Just stick your finger in knuckle deep to feel if it's damp and don't worry about overwatering until then. I can even tell the color difference in my smartpot fabric/feel that there is a good amount of water in the bottom by touching the outside fabric.

VIVOSUN 4 Inch Air Carbon Filter Odor Control with Australia Virgin Charcoal for Inline Fan, Grow Tent Odor Scrubber, Pre-Filter Included, Reversible Flange 4" x 14" https://www.amazon.com/dp/B01DXYMBU6/ref=cm_sw_r_cp_api_i_LVqSDbXCFH66J

This was my first carbon filter and it worked well. 35 bucks.

Thanks a lot for the info, I'm gathering all I need to make a DIY system now. One last question hopefully (though I might pick your brain in PM's down the line) do you suggest going with one pump for each bucket or one for both? I'm deciding on which of these to get but I'm not sure which size I'd need since they're rated in how many gallons the "aquarium" holds instead of LPH, and depending on whether I go with one or two. Thoughts?

Either something like this (pictured in use above) or this.

That's a 4" fan/filter though I might consider a 6" - three plants (especially in hydro) can get surprisingly large.

Oh, got it. I’ve just got a really basic one and it seems pretty quiet. It’s this style, but mine doesn’t have a brand on it so I don’t know if it identical.

4” desk fan

If you aren’t planning on getting a bigger tent I would stick with a 4” exhaust and a 4”/6” carbon filter. Here’s the link for the fan and one for the filter . I use a bigger fan and filter personally, but that’s because I plan on getting a bigger tent after my third or fourth grow. Based on the dimensions of your tent this should be a solid setup for you even if you go up a bit in the future.

This is what i used. I haven't been PHing my water while using this and it's worked fine so far.

I use that same setup. But I use this pump and two airstones for more bubbles.

I've used this with success...

would this be good for more potassium? https://www.amazon.com/Hydro-Organics-J05299-Meta-K-1-Quart/dp/B0001YC41S/ref=pd_sbs_86_5?_encoding=UTF8&pd_rd_i=B0001YC41S&pd_rd_r=6WK75FY6TGDZAJS9YNFQ&pd_rd_w=o8OQi&pd_rd_wg=JUxSM&psc=1&refRID=6WK75FY6TGDZAJS9YNFQ
