Flexwatt in divided T8

[RobertsKitty]

RobertsKitty, you don't have to run a herpstat 4 there are thousands of Hydrofarms/Zillas keeping reptiles regulated world wide.
Personally I would run about 18" of 11" along the back so you would have about 9x11" on each side.
Just keep in mind that heat tape doesn't really do much for ambient temps.
The lighting you want to use might help from the heat off the ballast but I don't know how much it will raise the temp.

It's the one I could get in a pinch so it will do for now, besides everyone on here either hasn't heard of them or thinks they are crap so... I've done some testing on the unoccupied side and the fluorescent seems to raise the temp about 4 degrees which should do well for the cool side but I plan on running it and keeping testing all weekend to make sure it's stable before returning the snakes back in.

I will either do the 18" along the back or the one up the middle. I feel like up the middle they don't have much room to fully lay on the heat but I like them having a choice of light or dark. Loki seems to prefer his hide in the light but Thor prefers as close to full darkness as possible!
