Yeah that's QB biggest down fall. Is their ends and corner drop off. I think those reflectors that are being passed around now help with it. But they are for more open air runs. Like in a room. To help angle it down instead of out. I believe samsungs diode cast makes them 120° which is what causes the drop off on the perimeter. But if you're running six boards. Idk y I thought you said you got 3. But anyway 2 groups of 3. With like 8-12 inch gap between them, will cover what your tryna cover easily. And your setup for flower going with cobs was the right choice. I like cobs. But for me in tents, I just dont like the footprint. Inside tents or reflective sides strips n boards rock. Free air/open space cobs are where it's at. Especially with some of the new reflectors that are coming out. They angle the light perfectly. I seen where migrow did a par test n whatnot on the new chilLed pucks. They arent as efficient as the website says. Go figure. But soon as I finish this veg build. I'm building a monster light. With those pucks and custom made star diode pcbs inbetween. For the 32x32 tent I use for veg now. No reason for me to veg in a 2x2x3 then to a 32x32 then flower. I can get them big enough for me in the 2x2x3. So I'm ordering 4 pucks lol for the 32x32 7.1sqft gonna run em all together softly at 525w may order em now.
