Been there, done that... Did you see me say that it cant be done? no sir you did not... i said that it does not mix, specially if youre trying to keep a sterile clean res, which i strive for
As for the killing the good bacteria, Yeah youre right. but if they dont help out then no point it adding them is there? Organics is about maintaining the bacteria so they can convert nutrients into a form usable to the plants..... adding a nutrient readily available to the plants defeats the purpose doesnt it?
