I was out in the desert this whole week. In the process of getting there, I forgot to tell someone to water the plants. Oops...
When I got back, they were surprisingly still alive and well!
@HighTV, I picked up these from HLG: https://horticulturelightinggroup.com/collections/quantum-boards/products/qb288-with-slate-2-heatsink
Then the driver off Amazon, which is a Mean Well HLG 240h-48a. And custom built the frame from 3/4" angle aluminum to fit the tent and get the spacing I wanted to cover two plants. The space in the middle can also fit a 3rd board if I ever want to get crazy.
Looking forward to seeing how they preform! Def a little warmer in the tent now but nothing unmanageable. Just need to supplement to keep the humidity up.
