ducting

looking at 24k btu mini splits to cool a 12x15 flower room running 6000ish watts of led+cmh, I have narrowed it down to a couple of choices, either THIS 21 seer wall mount unit by Aircon, or THIS 20.5/21.5 seer unit from cooper & hunter. Looks like they both use the same CMGG Toshiba compressor...

Question - I want to set up two 1k lights with external pass through air in a sealed room, air from outside passing through the lights, back to the outside, but have those external vents shut off and have the air circulate internally if the room temp is low, so that I am not wasting light...

Included a photo of my half assed cheap cupboard.. There is a 12" ruler ( for size) sitting on top of a Mars 300 full spectrum.. I will add another light soon... Will I need an intake fan ? Or will a 4" extraction fan on a carbon filter be enough to suck air into the intake ducting ? I will run...

Hi all, I've been running a flower tent (2' x 4' x 5' high) for about a month, and am constantly on the verge of it overheating. I've done a ton of research, built out all my fans/ductwork in the best way I can think of. yet I still constantly feel like my plants will overheat any minute I step...
