I apologize..I know this is Hydro thread but curious...does this info. apply to soil as well? So if what you're saying is true, I guess I been cancelling my bacterial supplement all this time. I just recently started using h202 and adding it along with subculture at same feeding cylce. Sounds like a bad idea UNLESS not relevant to soil. But what if I change it up and use h202 and no subculture at one feeding...and at next feeding use subculture and not h202. Still gonna kill the bacteria in the soil huh?? holla back with info. whoever knows...much appreciated.....

p.s. I'm on this thread cuz thinkin bout switching to hydro soon..thanx
