thanks man. its been a lot of work to get where im at. the clones going into this space have stalled out and im getting a little frustrated. got backups on the way in case these tank. gonna dim my COBs down. i think they are too strong and they went into shock. this run will tell me for sure if im gonna build more COBs or buy a few DE fixtures to run at like 750w since i dont have high ceilings. currently about to test out this new square wave DE fixture and see how it does. im also trying to get a hold of their premade LED fixture and see how it does. i still think for the money a DIY cob array will perform quite well and you wont be spending money on bulbs anymore.
