i've been using for about a year. simple line, very clean, lots of choices to experiment with. awesome results every time. i've used their components to make hot soil and their blends which are alot easier, love their fish & kelp product to supplement. they seem to be really focused on not using stuff contaminated with gmos, pesticides, etc, all the guys at my grow shop are really geeked on them even though they make less than when they sell the high-priced nutes - gotta mean something
