AN flat out kicks ass. hell you can call them and they will give you tips on growing your shit! they have there own forum to answer all there questions.
the urban grower promotes the sensi pro boxed nutes as being the 2lbs per light stuff.
anyhow i find you dont need all the additional stuff. just 3 part and some sort of bloom booster is nice. but they have every little thing you could need or want to get your setup perfectly dialed in. start small, add sups one at a time until you find that perfect balance
