The the only garden center around that I get my soil from, stopped carrying CoM, but they still have just about all the foxfarm lines. I didnt want to buy the foxfarm 50/50 or 70/30 stuff until I did alittle homework.Cause that's what they had and I can do high frequency fertigation so it didn't bother me.. When I mix up my own mix it is 80/20-70/30 I normally do this with bricked coco.. Like I said before the organics in the CoM turned me off but I am weird
