I can get promix cheap in large quantities.

How should I ammend it for 6'x6'x2'deep outdoor beds? One plant per planter...doing 12 plants.

I have used super soil and I am vegging these bitches inside soooo big it seems like they will be able to take a hot mix upon transplant with minimal issues.

I'm in norcal....every shop on every corner has a "custom whatever blend"....

I dont know what I am getting with local bulk soils...the biggest store in town is run by a money grubbing asshole. I like KNOWING what is in there. Its hard to go wrong with promix as a base...I just wanna get some ferts in there before hand

I have had so much success with Epsoma dry mixes in my veggie garden, I started to just mix that stuff in.

Thanks homebwy's!
