I've always like fox Farm Big Bloom, but it's the only F.F. product I really use any more except for their soils. I was going to use alot of their dry ferts to ammend my soil, but just went a different way is all. I would use their dry ferts in the future though, especially if in a tight space and just wanted to make a cheap batch of amended organic soil. I always thought they would make for a cheap short cut of sorts. I like R.O. products as well, I really like their H-P-K it kicks butt! Peace out.
