Okay so I wasn't sure if I should write this here or in Not So Spineless Wonders, so sorry if this is in the wrong place. So I've had my ball python for about a year and a half, and I've constantly struggled to keep the ambient temp up. I use flexwatt heat tape, but it only heats that part of the enclosure. The other half stays in the mid to low 70's. I've been using a bulb during the day which raises it up to about 80, but that's still kind of low, and it makes the warm side too hot. She's in a 4x2 pvc enclosure. Any suggestions?
