I grow in a hempy bucket and I use it day 50-53. 3ml/gallon with a pH 6 water and minimal flowering nuts. Then it gets flushed for about 2-3 days and then no water for 2-3 days so the plant dries some on the vine before harvest. I also use overdrive from day 42-53. I mix up a new batch daily as it 'foams' if left in the rez.

Worth the $ and time. I definitely notice a yield and density increase, especially on leafier type flowerers. Never noticed a taste difference. Never noticed headaches. Ive never moved the lights up but I have a light mover and I usually stretch out the move distance on that last week, perhaps that helps.
ecofrog Reviewed by ecofrog on . Gravity flower hardener Is anyone familiar with this stuff? It was recommended to me but I have no idea what it is or what it does. "Flower hardener" sounds kind of scary to me. What does that mean exactly? Worth using? Thanks for any words of wisdom. :) Rating: 5
