I have my new BP Pablo in a 20 gallon glass tank.

In the old set up, I had a day light/heat bulb on one side and a night black light/heat bulb on the other and switched between them every 10-12 hours. I had initially struggled with the humidity, but a friend suggested I put foil on the screen, leaving a 5-6 inch gap on one side for circulation + then I put Pablo's large water bowl directly under the day heat source and misted twice a day and it held steady between 50-60%. I didn't have an accurate temperature reading for either the hot or cool side, just the ambient temp. His substrate was reptibark.

After more reading, I switched his substrate to coconut fibers which I read holds humidity better. I took out the heat bulbs and am now using just a 100 W ceramic heater on the one side for the hot side with no bulb on the other, on the advice of a reptile store worker. I also got digital thermometers to measure the gradient.

I noticed last night that my temps were low so put foil back on the screen, hoping to hold the heat from the CHE. Well, it has held the heat up a little but the humidity has shot up to 65% and my temps are out of whack and way too low still -- 81.7 under the CHE and 70.3 on the cool side.

I really don't have the funds to go out and buy anything right now to help the situation and I'm tempted to switch back to my previous set up with the bulbs because at least they'd help burn through the humidity and keep the tank hotter. Am I right?
