HUMIDITY increase...HOW!!!!!

Quick question.. How can increase the humidity in my small grow room...? When my heat goes up, the humidity goes down. Does that sound right? My room is at 45% humidity now..

45% is not bad. you can get small humidifiers. or you can try putting a small bowl of water beside the plants

big bowl or box of water. fan blowing across the top of it.

I have a little fogger/personal humidifier that I got at Wal-Mart for about $30. You fill up the tank with about a half gallon of water and it will last about a day on the low setting. My clones fuckin dig it.

Ok cool!! Any other options?
