One and all,

First post, thanks all in advance.

Specs - 3'x4' indoor closet, hooded 600W MH vented to roof with squirrel cage fan, box fan in ceiling, mylar all around, 6"x10" floor intake vent, room/closet kept off HVAC system during winter. Cannot use windows.

Having tremendous heat problems. No matter what it stays 80-85*. When I use the central HVAC it only drops 5* or so and still found it above 90* in the middle of summer.

Ruined a couple of crops already. THC being baked off the plants (guess)?

I'm considering a portable air conditioner with 10,000BTU and setting it up in the (unused 110 Sqft) room and venting via the attic.

Anyone else have experiences with this problem and found a solution? Think the above is viable?

Again, thanks in advance,

Peace,
JF
