build a soil kind of seems like an organic version with all the individual ingredients
dr earth, down to earth, fox farms happy frog all offer a single product that can be mixed into a base soil and bring it, but how often do you see posts about someone being confused as to what bat guano to get to mix for their veg blend etc
the point of organic is to not need as much fussing as hydro, you don't even need molasses for aerating stuff
Agreed! Build Your Own soil, replenish old soil (after baking). ;o)
