Alright so I went and bought an acurite thermometer and a dimmer to start setting up my tub. I got it so my little UTH was at 93. I taped it to the tub which I constructed to keep in heat and humidity. I cut a large screen portion out and did the duct tape and foil DIY over it. But my one little heat pad can't heat the tub to 80's and my room is about 74-76F. What can I do to get all my temps right? I'm thinking about trying to find another tub because this sterilite one, the one with the green handles, isn't flat on the bottom, although I don't know if that makes any difference.

Thanks guys!
