how many cobs would i need to achieve 15 zips in a 4x4 tent if a did away with cmh . im sure i read a post of yours that said cobs can get a bit
too intense thats why you stuck with just 4 ??

You started with the hps correct? If so be happy you didn't waste thousands on leds before you realized cobs were even a thing. Hps - cmh - cobs is the fast track.

no joke! You'll kill it with 4 cobs in there and the cmh

I'd do 6 and run them soft, 50 watts each for a little more spread when going for big yields. 300 watts of COB lighting should get you a pound, all else being just right.
