    DIY with Quantum Boards

    Not really. Should be really good You could get away with less for sure. Maybe dim it some if you feel like it's too much.

    With the Slate 2 heatsinks these boards do well at 150 watts each

    The max current rating is the same as LM561C. Honestly max current is 3.2A ... 200ma X 16 strings. I believe @robincnn is being conservative because most meanwell drivers give a little more current than rated.

    Grandmaster Level - HLG Quantum Boards vs 1000w HPS side by side (youtube)

    You can turn them up to 360. The heatsinks are fine with that..

    HPS contains 0.0% UVB and as far as red/far red the QBs have more.

    The humidity is probably the biggest factor in the potency loss. Everyone knows or at least should that you lower humidity at the end of flower will increase resin productivity..... I sure 80% humidity can have the opposite effect.

    The low temp is 81? What is the temp in your room outside the tent. Yeah I messaged you way back when trying to hook you up with a duct cooled version. If you put the units in those hoods you can do the same thing you are doing with the HPS. Trap the heat before it enters the grow environment...

    Quantum Board QB 288 V2

    2 of these boards on a 480H-C2100 on a triple heatsink active cooled should do better than a 600 Hps. Using around 150 watts less. With optics it will definitely be impressive. I wouldn't run them at that much wattage without an actual dedicated fan on the heatsink.... The little bit of extra...
