Sorry all I use is Fox Farm brand of stuff...I use there Organic Grow Big for vegging and I use Tiger Bloom for the flowering stage. Look in your phone book for Hydroponics store and go there alot I am on a first name basis with the shop here I go to. The guy in there tells me about new products that are good and the ones that are shit. I also use the Fox Farm Ocean Soil mix with a small bit of lime added for PH control. But its a verygood all around mix when my plants are done and harvested I dump the remaining soil mix on my garden outside.
