after watching a few grows of a friend and seeing the yield increases of upto 30% using House and Garden nutes and their feeding formula...they offer some solid results with a simple 2part mix ....one grow was on GH flora 3 part and the other was using AN's mess of products...and H&G outperformed both hands down..I am going to do a grow with them when i get back to the states in my grow log myself:thumbsup:
