The gh didnt do as well as the an 1.01 lb /light and only 6.8%thc. even grow tec had a better 18%thc. I would accept higher thc for slightly less yield. But there was no comparing the 2 in the link I sent.
i will say that challenge was a little loaded, they were using the sensi pro pouches wich are everything in one, bud blood, big bud, carb load, all the extras,,, and with the others they were just using the base nute with no bud enhancers or nothing, so it was a bit loaded,, with general they should have used their bloom stimulator, and diomond necter, at least..
i am an advanced nute man, but that challenge was loaded..
