But i will say i was a skeptic for LEDs. Loved me my hps.
Then i tried COB. First run was a bit of a disaster. But even so i knew i would not go back to hps. And i have heard that over and over again from guys who have gone to COBs.
I used cob lighting and it's great for veg but doesn't compare one jot to using a gavita 400v in flower. The light penetration is still just not enough
