    Anybody know what the minimum Watts you want in a 4x4 tent per square feet? Also what wattage per square ft is considered perfect without co2?
    I have 3 rows of 4x qb132 3500k running at 250 Watts per row. Total of 750 Watts actual light, like 840 pull at wall. No idea how to figure it out haha. Answers greatly appreciated!

    50 watts per square foot is the rule of thumb, I think. So 4x4=16, 16X50=800 watts. You want to look at the power draw from the panel (not watt equivalents), so it sounds like you're golden.

    Edit: typo.

    QBs maybe a little different from your average Leds which 40 or 50 watts Per square foot is more then fine. so actually 30 watts Per square foot is fine from what I read by Tbone if running QBs. Good Luck
