I’m in need of a little help picking the right AC for my set up. I live in Southern California, and as you already know, it gets scorching hot, especially in my garage where I'm setting everything up. I have an 8x16 tent running a Current Culture UCE18XL, with 3 Spydrx-Plus and 2 Ray 66 led’s, with a total of 2220watts. I have a Quest dual 155 dehumidifier, that's on the outside of the tent for the humidity, but I'm stuck on the right AC setup. Pleas help
Mini-split. Get a decent one, that will not die in the heat. With that sort of approach - you can use CO2 and not exchange air as much. It probably won't hurt to have a way to power the mini-split when the power is out. You can deal with skipping the lights, but a long bake is really bad.
5-6k btu cooling for every 1000 watts of lighting is what I have always ran by. I run hids tho so this may be a lil more than what you need running leds. A little oversize is better than undersize but super oversize not good either.
