That's what I was gonna tell ya. Don't know what your budget is, but I got one of those whole house humidifiers from Sears. Place it outside your growroom and it will raise up the humidity a lot. http://www.sears.com/shc/s/p_10153_12605_SP100A1824S143937129P Plus, that bitch holds like 14 Gallons of water, so it runs for a long time on the high setting, and it has controls to raise or lower the levels.A humidifier does not have to be in your cabinet. If it's in the same room it can help quite a bit. Peace Jack
