    Grow it LED by James , customs is the next gen , next level custom LED builder. Grow it LED is better then ChillTech and Grow Mau5s build. It blows it away and costs half the price. 850 PPFD inside the corners and 950 in the middles , perfect for 20 inch hang , 100000 Hours of life and 5×5 footprint for 600w and 2.3 umol/J . No hanging the driver , and its cooler , stays alot cooler. It also looks so much cooler and hs customizes the lights .

    I agree with You, more reds. Double the reds to 8 in each pucks. Add one more pucks for 6 total in a two rows of three configuration rectangular light. And add another driver.

    Those stickers really need a plastic bag??? Thought we all were trying to reduce the plastic winding up in our oceans Chilled Logic/Grow Mau5. Sexy light but I'd like to see less packaging where possible.

    Plants don't show much photomorphic response differences between 2700k and 4000k, which most of the full spectrum leds fall under. Outside those ranges you'll notice internodal differences. And the difference between a 2.6 vs 2.4umol light only matters on paper. Real world application is negligible at best.
