has anyone ever built a temporary greenhouse to house their torts for the winter.. my sulcatas love their outdoor enclosure so much i am haveing trouble decideing if i need to build them an indoor enclosure wich you can tell they are not very fond of.. i am thinking of building a greenhouse around their cage they have now and just take it down every summer and put back every winter.. any ideas or opinions on that , and if it will work i need some structure ideas as well... even if i put up the green house i will still use usb lights and heaters..
