Miracle Gro Bloombooster for flowering, fox farm and MG potting mix as a medium. Dont knock it till ya try it. That is unless u live on a farm and have access to fresh manure.
I dont believe any one is better than the other. I'd just look for a veg nute that isnt ammonia based. Around 3-1-2 NPK. For Bloom id use 1-3-2 npk. i use botanicare pro blend.
