That's sick!! Damn, that dude knows his stuff..
So I guess a plant being purple isn't necessarily a good thing. 20% stronger, I'll go w the green! haha
That's tight tho, I learn more w every grow.
Shit I remember one of my first grows...7'x6' room (basically sealed) whole floor covered in plants, No duct fan on 1000w halide, no Co2 added, SOIL, HALIDE thru flowering...They all did pretty good, until flowering then it was game over. no air/co2 it wasn't a great yield LOL
