Is a Split T8 too Small for an Adult?

[The Serpent Merchant]

It's typically around 70 but can get much colder if the heat is off, which is out of my control sometimes. I thought heat tape only heated the surface and not the air? Or are things a little different with PVC?

These cages retain heat much better so every little bit of heat in the cage stays there. If the room stays around 70 most of the time RHP's aren't necessary. But I would recommend getting 2 of the 18" fluorescent light fixtures with the cage from AP. An 18" fixture will add a few degrees into the cage and should keep things just about right.
