I am planning on ramping up from my 2x2 tent with 1 qb288 v2 from HLG. I was originally thinking about getting 6 lights on 2 heatsinks with 2 power supplies in a 5 by 5 tent. Now I'm thinking about getting a 8 x 4 tent with 6 lights on 6 heatsinks, still with 2 320w power supplies. in either setup I want to run 6 plants. In the 5x5 tent I'd do more of a sea of green style buy in the 8 x 4 I thought i could but 4 18 inch pots along the back and 1 on each side with a light directly above each.
