Whys dont you go one further & bury bubble tubing in a spiral fashion directly into the pots/rootzone.
That's what I'm doing, anyway.
Here's my last grow with this technique https://www.icmag.com/ic/showthread.php?t=135017
I don't risk hurting the micro-life with peroxide, though.
H2O2 will start to instantly oxidize organic material, including the beneficial organisms I'm trying so hard to nurture. I used Peroxide when I did chem hydro, but have abandoned that when I went organic
Pure water is just dandy. It's the peroxide that's the issue. I think thiis is all fascinating also, and I'm grateful for your thoughts Scrogerman
A couple years ago I found that switching from H2O2 to molasses worked pretty well. I didn't know then that I was likely feeding beneficial Lacto-B bacteria, which is a like a guard dog for many harmful bacteria. I then started heavy bubbling of the res, and added a heater of all things. Despite the heat and lack of H2O2, things really responded well and I never once had bad bacteria colonize in my res.
sounds dangerous to me bro! 'Aerobic bacteria'(O2 loving) being the prominent words!
In that vein does anyone know at what ppm of DO does it become detrimental to Aerobic bacteria? as an oxidiser?/harmfull?
So here's my two cents on the subject. I have been growing with this method for the last 18 months. Five gallon ( or close to it) kitty litter buckets. In the bottom I place a 4 in dia air stone, cover the stone with approx 3 to 4 in of red lava rock.
I place a piece of fiberglass window screen down next, it helps keep the growing medium out of the rock and help keep the roots out of the rock also, I found that out after the first run.
I use coir, fine and chunky, mixed with EWC, bat guano, blood meal, kelp meal, perilite, vermiculite, dolomite lime and beneficial microbes.
The air stones are hooked to a 3 psi air pump which puts the air to the roots via the rocks which are the water res also..
Any way one can get more air to the root system is beneficial for the plant. Commercial flower growers inject ozone in to their water for the added oxygen.
Watering is always from the bottom via the site tube on the side, one thing this does, is help stop fungus gnats as the soil surface stays dry.
This is the only method that I've grown with and I have had great results. feed very little nutes , not really any need for them I've gone both ways with nutes and with out. Generally I water every third day more often when the plants get bigger and use more.Also I noticed that the nutes I have been using for bloom says that it can ferment if left in an anaerobic environment, the air stone prevent that.
Each pot holds about a gallon when you first fill them. I've had great results, will be trimming the last grow today and will post it in the grow diary I've been writing.
