two 1 gallon gugs in cooler full of salt water for 12 hour light cycle droped a 10x10 room 10 to 20 degrees depending on temps. I had over 100 degree outside tepms and it helped keep room at around 85.

You can also scale ut up and hook a mini pump to cooler to run a air cooled hood . or use dry ice and put small hole inpipe in cooler to slow release co2. Have not rried the co2 idea
