Advice On Lights Please?

[GT21]

Well we have seen guys hit 1.6 -1.8 gpw with cree at lower drive current from growmau5 and it's only a matter of time before someone else finds a better strain like bigbud,some something higher yielding.and if ya had a 650w fixture that covers like 4 x 6 and used .Mover to just get it to cover 2 more feet so it's only moving 2 ft max I could see it possibly happening,but I need to see pics for sure.ya just can't say 3 pounds from 650 and actual growers just believe it haha.
It might be dry but still has a pound of lumber on it because it was left on the stem lol.

I have seen guys grow 2 pounds per dwc auto...pro shit... Lets see 3 pounds off this light... I want to see if he can beat the law of thermodynamics
