Hi there! We have a 3 year old 14" Long by 12" Wide Sulcata Tortoise. We would like to move him to the backyard to live now that he is bigger but need a little advice on housing and heating. Option 1: We do have a greenhouse, it is pretty large but it is made of a very heavy plastic. Would it be best to put a house inside the greenhouse for him? Or we could put the plastic house we have got on the side of the house.

As for heating options what should we do? Would a heating pad be the best option? If so what kind and how many?

Sorry so many questions. We just want have the best home for our tortoise! Thanks in advance for your response!
