The kingbright 320watt was great $250 shipped in 5 days, cool temps and the flowers did really did well. 2X4 tent 2 plants in different phases so 151watts per plants. These QB where like 50% less that my HLG in the 2x2 and work about 90% as good but the last 10% the HLG can give you is not always needed if you oversize the light to start with. I'm going to reveg and clone the stump.
