So I currently have my chameleon in a exo Terra 45x90x90 and I want to upgrade him I will be building his enclosure myself I have an empty storage cupboard that measure 60cm deep its 110cm wide and because my upstairs is a loft conversion towards the top has a slant so the tallest part measures 210cm but my question is will my uvb be ok to use at a slant? Will it still be effective? And will he still get enough uvb?
