You have HO T-5's - right? I am using Light Warrior seed starter media from Fox Far, Latest batches, I have been mixing in coir and some NAPA oil absorber.
Yes what you said makes complete sense. I am using about the same H2O2 solution - I make it up a gallon at a time.
Yes the constant heat helps. I am not doing that as I am rotating trays - I only have 3 heat mats. My lights are on a time in the basement at 12/12.
I don't use jiffy pellets and do not know what Root Riot cubes are. Are those Jiffy pellets the ones that have a media like a woman's hose holding the media in?
If so, I quit using them as they can strangle roots - I discovered that whn several plants died for no apparent reason. Dug them up to check roots and the roots never made it thru the hose material.
