I literally have to spray it a few times a day and I think it has dropped to 40% a one point (per Acurite thermometer). The thermometer keeps record of the lowest and highest percentages. I sprayed it about 3-4 hours ago and it spiked to 80 and then dropped to 57.

Both the UTH and CHE are plugged into the thermostat now. The temps with the 150 watt stay stable and the CHE doesn't run at 100% constantly anymore.

That's a very good point about high humidity and it not being warm enough. I guess the low humidity is the lesser evils than it not being warm enough lol.

Should I try to put in a second water bowl? I don't have much room to work with lol!
