I'm setting up a new grow room where space is abundant, but there's no inconspicuous place to put my 12,000 BTU window AC unit. I also don't have the $1200 needed for a decent single zone split AC unit, or even $500 for a decent dual hose portable AC unit due to moving costs. I noticed there are vents on the top and sides that draw air in for the fan to blow it over the radiator and out the back. What do you guys think about building a box to go over this with 2 sealed compartments? Each compartment would lead to a 6" duct. The compartment over the intake vents would draw air in from outside and have an inline booster fan to help out. The other would exhaust air back out with another inline booster fan. The unit, along with its new hat, would then just sit on a table inside the room, essentially becoming an ugly, dual hose, non-portable AC unit. What do you guys think? Am I nuts? I know it's not ideal, but it should work for a couple rounds until I can get the split AC, yeah?
