I have no issue at all with the boards. But the 90 cri stuff is providing way more of the deeper red wavelengths.
I think the 288’s are running around 2.75 ųmol/joule at 1400ma. It’s really hard to pass up that kind of efficacy at around 75 watts. I’ll probably get a 1750ma driver and dim to around 1400, but have a few extra watts if need be. Then run the cobs around 700-1050ma in flower.
I don’t think the cobs will have that kind of efficacy, but should still be well over 2 ųmols/joule and I think around 65% efficient at 700ma. Price I’d be willing to pay. Probably $400-500 all said and done.
