Check GH web site and get the low down on it first hand.And compair to other frets makers and see what you think.I'am using GH Flora 3 part with Diamond Nectar and later add Kool Bloom in the flower cycle.So far everything is going great.It's easyer to ph the water too.I just check that maxibloom It's a two part super conetrated plant food along with Maxgrow.It's for fast growing plants.I 'am happy with the 3 part flora nutr.
Peace
