Thank you so much sounds totally workable! I am heading to work right now but when I get back home I will send mesurments and wattage but I can tell you I have 3 heat ceramic coils in the black domes and also a uvb bulb that shines on them from a distance for 12 hours a day@Mrs Toonz I was thinking about you situation, your heat and humidity is escaping so you need to close the enclosure some how, it looks a good enclosure so you don't want to dismantle that or have to start again. Why don't you add an apex on the open area, made of wood with a perspex front on hinges. Could even use a plastic sheet for the window with some creative thinking. This way you can hang the heat sources from the apex too. Also it will save you money on electricity because your not loosing the heat all the time.
Whats in those 4 holders.
A quick sketch to plant the idea.
