I have 4 x 12 year old Herman's and I'd like them to live outside all year until i hibernate them. I have had a kennel type house made for them and need to know exactly what lighting and heating they require. I'm thinking uv + basking spot at one end and something cooler at the other end. I'd welcome any advice please.

What size is the house ?

These measurements are for the internal space and not the overall structure.

Overall length = 56"    Height = 2ft 3"

This is then divided in to 2 sections, bedding area H = 27" D = 19"  W = 18"

there is a archway leading from bedding area to the larger part, L = 3ft  H = 27"  D = 18" this area has a  door for them to escape outside. 

I was thinking basking spot + uv bulb in bedding area say temp of 30 (daytime) 20 (night time) then 20 day and night in larger area + uv combined with 2 magic eyes?
