fuckin shot in the dark here, if you need like INSTANT results, and if your rooms not TOO big


Go get you a big ass bowl, get some dry ice and set it into your grow room.

If you have a CO2 supply, turn it off. As the Dry ice sublimes into the air, it creates CO2, and also cools the room a bit. Now, you'd have to have quite a bit of dry ice tho just to cool down a simple closet grow room



just givin ya options
