How many watts do you want it to run?

Idk from what I read would it be more efficient to run more cobs lower watts? When I get more funds down the line I'll add a few more cobs and another driver, so my question is if I'm not concerned about watts but more about efficiency would that make it easier to give me a better answer?

I mean what wattage do you want overall, for the whole thing. You'd choose your driver based on that

First you must decide what PPFD you want then you buy COBs and drivers.

I just saw a post that a guy with the exact same setup using the hlg 320-1400 his grow looks good so I might just go with that it's for a 3×3 area for now

Are you in a 4x4? If so That would work but I'd consider 2 smaller drivers over one larger driver. You could also make 2 frames vs just one too.

I made one frame but went with 2 cob drivers on this one. I wouldn't do it any other way.

I was kinda hoping that you would reply bigsmo. What size drivers would you recommend? I might just get a 4×4and do like you suggested and build 2 frames

Happy to help.
Hlg-120h-c1400 would run 3 cobs at 50w each.
For series wiring. More expensive but the easiest install and safest for the cobs.

Hlg-185h-48a would run 3 cobs at 52w each
For paralell wiring. Less expensive option, this would also require a little more wiring which is not a big deal unless your OCD. Also the chance of thermal runaway. If one cob fails the others take the power load.


I actually have both drivers going myself and not had any issues. 3 cob bars are very nice and easy to install, move and adjust. That pic above is a royal pain in the rear. It weighs close to 50lbs.
