First rack project

[The Serpent Merchant]

AP's hides are huge, I wouldn't use them with BP's

Reptile Basics is the place to get hides and flexwatt.

I would use a single strip of 4 inch or 2 strips of 3 inch.

1/3 is a good rule of thumb. So if you go with 4" and 3" that will give you 7" which will be just below 1/3.

The only problem with mixing sizes is that it will require 2 thermostats to run. I would only use 1 size on a single enclosure/rack.
