i had heard good and bad about GHS. thanks for leading me away from them!
I bought them in my early days of growing and though I was a newbie everything else was practically growing itself except for their shit, which didnt even like to germinate. Yeah that one time was enough to burn me on them

If you'd like a cut, PM me and I can help you source it.
appreciate it! maybe next time i'm headed to Denver or points north, i'll give you a shout.

not too big on 4+hrs roundtrip for some clones but if i'm already gonna be up there....

and ethos collective does lemon og haze which is a cross of super lemon haze with ethos OG. so many strains, so little time

I was in the Springs yesterday, got me some nutes. Wish I'd have known...

I know this is answered all over the place but it's a lot to dig through you content generating genius you :)

How close are your COBs and what kind of wattage are you running per cob? I know you're using the 72v version. Just curious on distance vs wattage.

Also are you using lenses or reflectors?

No worries! Volts really only matter when you're trying to size by mA, or milliamps. I'm running four Cree CXB3590 3500K 72V CD bin chips per Meanwell HLG-185H-C700B driver.

That means 50W per chip- but wait, there's more!- because I chose the B version and run the dimming leads capped off, I get an extra 8% for 54W per chip, 216W total. The driver takes 8, for the from the wall observed total of 224-225W. Twenty four of these modules make up my run, for total a of 5400W.

I'm using KingBrite glass lenses, 80 degrees. As you can see from the pics, I paired up the chips at each end of the module, this so I get an optimal light distribution pattern when I mount them in the array.

I built my lights to throw as far as 30" and for the pattern between chips and modules to overlap as close as 18". Because of the size of the array, the former number only really matters at the edges.

...and heat matters, too; efficient fan cooled sinks will help the chips run noticeably more efficiently than a fully passive setup with marginally small heatsinks. My cold water chilled modules are actively cooled to about 55F, allowing them to run roughly 10% more efficiently than heat sink to ambient air designs.

Yeah, I'm a lil proud of that, lol

I knew most of that just couldn't remember the current. I'm upping mine from 700ma to 1750 with the 36v cobs.

Was converting based on current :)

Running them bare with passive sinks and fans to try to coax that last 10%ish increase from the cool junction temp. Super jealous of your chiller.

Was hoping to try to scrog up the wall in my new room like you have to maximize space, but wasn't sure if I was ballpark wattage wise. Especially taking optics into consideration.


You rock, thanks for the reply :)

If you run 35W/sq ft of COB LED or more, you're going to do just fine. It doesn't matter if it's vertical or not, calc is the same. The more efficiently you run those chips, such as cooling them well and/or running them very softly, the better.

I'm looking at 65+ w/Sq foot in 2Ds.

Was debating angling the heatsinks (aluminum hsusa versions) at like a 45 degree angle to the wall, so I can go up the wall too instead of a more flatlander scrog.

Just playing with possibilities really

That's kinda overkill. Remember that LED is more efficient, not less. This you need less W/sq ft. Trust me on this.
