i have been hearing great things about advanced nutrients organic products! i always used fox farm products in the past but when i start up again i think i'm gonna switch to the advanced. after all it is made specifically for mj! harvest moon hydroponics carries all the advanced nutrients as well as fox farms and many others they have a few stores in the us, if your lucky there just might be one near by. heres a link to the store finder http://www.hmoonhydro.com/
