I have a 2x4x5 tent with a 400w hps on one side and a viparspectra 300 burple that’s 135w actual watt supposedly. Have a 32x32” with 8 t5 bulbs for veg, and a 2x2’ with 2 135w cfl for seeds and clones.
I originally bought the 400w thinking it would be enough for the 2x4 but felt like it wasn’t enough right away, I added the 2 135w cfl and it seemed to help, so I bought the burple to try it, it was for supplemental lighting.
Along the way I stuck some seedlings in the flower tent as a test. It was jack herer and they did amazing. I believe it was the light intensity they liked. So after reading all the quantum board stuff and looking at hlg mars spider farm I ended up going with the kingbrite boards. I got a 240 w in 4000k for the 32” tent and a 125 w in 3000k for the flower tent. The people were no nonsense, and the girl even gave me a 2$ discount, not much but more than Mars offered, mars is a sponsor at thcfarmer. I have a grow journal there and asked for a discount, I would have used all their stuff if they had.
In construction there is house wrap duct tape plywood etc of various types. I understanded quantum boards as a trade reference. There’s an led street light outside my house, I looked at it when it was off, I called it a quantum board, idk. Lol I want to see results and have reliable products. I hope to see it with these, have to be better than what I got now. And kingbrite has great customer service, easy transaction. I think their doing a great job.
