I've been using the H&G line(soil&flakes) +full additive line in ffof and light-mix, off and on with reasonable success. I've discovered coco and decided it's what I like. I'm currently using the coco's a+b with full additives. I'm wondering if all the additives are worth the $$ ? So, if you use the coco's a+b as a base, but not the h&g additives, I'd like to hear how you do it, and what kind of results you get. Thanks...
