Okay guys I need a quick check. I've read through all the articles and arguing here and I'm starting to get the picture, but you all are arguing so much its hard to get a final answer. Let me set something straight, we are all adding and asking advice from different experiences, different variables have revealed different secrets and boosts to everyone's system. Aero and hydro are booming because we are all getting better at it, but we do garage grows, cheap grows, start up grows and try to cut corners and simplify systems to fit our needs. While a lot of the stuff in here is contradictory, if you read everything to preface it you can get an idea of what will work best for you.
Good for you, you inc your rep on a weed forum!! You've just recorded something on the internet and you're bragging about it. That's almost as dumb as it gets, and to get bent out of shape about it is even dumber.
I have been a long time supporter of the GREEN INITIATIVE since HS. I don't hate on anybody who supports, its about love people.
Now I'm going to explain what I have going on in my room with my temps and I hope I can get some straight answers and MINIMIZE the senseless bickering.
I'm trying to make a true Aero system, not DWC NFT or EBB & FLOW.
I custom built my tray, to fit my space, it's about a foot and a half deep. Deep enough to let the roots hang, but they're not going to sit in a pool of water. My tray is drained completely. My res is next to it and the water temps are pretty high, pushing past 75-80. Yes I realize this is very warm. And am trying to fix it, but I'm trying to determine the possible risks as to letting it be. I've already lengthened my intervals from 2.5 to 4 on and off. While the res is pushing into the 80s, my grow tray isn't, I think it is 75 MAX.
The plants are grown in 3x3 rockwools sitting in 6" net pots, they have about a buffer layer of leca on the bottom and an inch of leca on all sides, so it breathes and isn't trapped in the heat and moisture, yet. The roots aren't dangling yet, they will be in a week as long as they can survive in my 75 degree tray.
The reason my res is so warm is because I have a big ass sump pump in there. The reason I'm using such a huge as sump pump is because its powerful enough to turn my misters into the kind of aero system I want. The increase pressure was my goal, giving the roots the true aero system I'm trying to design. I do have airstones in my res, but now I'm thinking I dont need them, because I'm going for true aero. And my roots will breathe just fine from the misting they are already receiving.
I do have CO2 generators to supplement plant growth, which is why I'm also less worried about the heat, because if I'm trying to make sure they won't be limited by a lack of any of the basic elements of growth, i.e. water, nutes, CO2, air, light.
Cleanliness has been the biggest rule in my room, thereby eliminating the risk of pathogens.
So my questions are:
1. How safe are my roots? They can breathe, it is warm, and no water is touching light.
2. How safe is it to flush the system using H2O2? I understand it kills the pathogens, anything growing in the water because of the light and nutes, and I used it to clean my system before I started my grow. But I am still scared to wash my system with it while my plants are in it.
3. Eliminating my airstone will also decrease the chances of unwanted growth in my res, right?
