I've been adding Purple Maxx twice a week with molassess. You do have to carefull if you use Gravity with the Purple Maxx. I turned one whole crop yellow because I didn't have room to raise the lights.
killerweed420 Reviewed by killerweed420 on . purple maxx On the bottle it says to use a 2ml. per a Gallon of water. So this is .5ml per a quart? It just seems like so little. In fact i had a hard time measuring out a half ml. May have been more like 1ml. I hope it doesnt fry them. Anyone have experience with this. It seemed to be a drop in a bucket. Rating: 5
