It’s in my grow off post, Jan 27th update. This is my first full blown DIY. The first light I built was the 2-288 kit that came with all the parts. Then I bought parts on Amazon and HLG to build a simple QB304 board with a 1050a driver, and then this one. I have an upgrade to a 4x4 or 5x5 tent on my mind and would probably do a couple of these, maybe 3, if and when that happens.
