So I have a great cob setup its a tasty 300w 6 cob design. It works great in a 4x4 but it really rocks a 2x4 which I use for flowering. My question is to all the cob geniuses on here can I upgrade the cob chips to say Citizen, luminous etc... I'm just curious. I am however thinking of swapping...

So I ordered a kit 250 watt 5 cree cxb 3590s and it came with a meanwell HLG240H-C1400B. Works great.... I ordered another what I thought was the same kit but the driver this time is a HLG320H-C1400B, same COBS and all... if I hook this up and it goes to full power will this push too much to my...

I have a bar of 5 Cree CXB3590's running at max 250 watts, that I have just moved over the top of my seedlings. They are only about 2 weeks old so just little gals. I have the LED turned all the way down and up about 21 inches above them. When can I start cranking up the volume??

So I went to go continue my painfully slow upgrade from HPS to all cobs (which I guess seems like everyone is on QBs now?) I had bought Crees from timber before and loved the quality and great customer service and everything... I go back now and there are no Crees to be found on the actual...

So I think soon I should be able to pull the trigger on finishing my upgrade to COB's. My idea is to use 5 bars each using 5 cobs spaced approx 12" on center on each bar then have each bar approx 12 inch away from the other bars effectively getting 1 cob per sqft. in a 5 x 5 space. My first bar...

So, I've decided to delve into a 3x3 cob build and trying to maximize efficiency at the wall. I was hoping to pull off a HLG 320H-c700 with 12x CXB 3590's, but when I divide the forward voltage of the driver with 36v it comes out to driving 11.8888 cobs. Whats confusing is when I calculate...
