Not heard of them.. although bought a bag of the smaller ball bearing size slow ferts.. Has 7n- 7p- 7k value so should be good all round..
MJ plants love nitrogen and use large amounts..
Must start to look for plots, and prep the soil..
I've been flowering since Dec 24th.... My calendar suggests it should be harvested today, But i can report that due to the biggest freeze in 30 years the grow is somewhat 3 - 4 weeks behind...
Oh and I found this place if anyone is thinking about a cfl grow...
