Looking for some help or suggestions I am currently running 5 citizens clu-048 1212 gen 6
With a hlg 320-1750 in a 2x4 tent everything works fine but am running into heat problems going in to the 80 I recently got a 2x2 tent and was going to take two cobs out and run them in the 2x2 with using hlg 120-1400 one running 2cobs in the 2x2 and one running the 3 in the 2x4 would this be enough to lover temps or should I use the hlg 120-1050. Sorry for the long post just trying to put as much info out

If you are using the same power supply then it will increase temperature if you take out a couple of COBs

Correct 2cobs in series in a 2x2
And 3 cobs in series in a 2x4 @1400 or should I keep all 5 cobs in the 2x4 and run them @1050
Ultimate goal is to lower temps in my tent

Putting less wattage into the tent will lower it's temperature any way you choose to do it. But personally with that space I'd increase ventilation as 320w will be a great amount of light for it and should give you the ppfd you're looking for.

Thanks I’ll see if maybe moving things around in my room I can get my tent closer to my window unit 👍🏼 Appreciate y’all
