500w DIY led 4x4 organic 2.15 lb grow

Looks awesome!! Great looking grow. I'm looking into getting getting some Cobs. I'm a bit intimidated by the build, but I think I'm going to give it a try. My current LEDs are doing ok, but not as good as I hoped. They simply don't have enough penetration to get to lower branching.

Do you defoliate at all?

Can you talk about the DIY 5 Gal bucket Co2?

I had to revive this one while searching for COB grow journals. 2# off 500W of COB's? Bad to the motha-fuckin-bone baby
