I figured out how to control the humidity, but now a cold front came in, and my temperatures are lower than they normally are...any ideas? I already have my heat pad up quite high and I don't want to turn it up anymore...the warm side is only at around 85, and my cool side is quite low at 73.. I have some lamps up now, but the temps don't seem to change...Should I invest in ceramic heater bulb? Thanks.
