i don't think any of the major lines of nutrients are "crap"...they just want to sell you stuff. its up to you to weed through it all......nm.......and decide whats useful and whats snake oil bullshit. i tried several bud boosters, and imho, they're all garbage. none of them are BAD for your plants, they just aren't good, either. picking a decent pheno, giving them proper nutrition, good ventilation, good light, controlling heat and humidity, these things are going to do more to get you good big tasty buds than any bottle of shit the guys at the hydro store are trying to sell you
