I converted a 6ft bookshelf into nice new home for Leonardo, my 4 month old Sulcata. Went from a 3 ft to 6ft. Since this enclosure is so much bigger, I am having a difficult time regulating heat and humidity. Right now I have a 100w ceramic heat lamp and a 75w bulb. One end is mostly covered as his hide box. I spray water several times a day on the cedar mulch/ Coco coir mix substrate. I think I may be using the wrong heat and light bulbs so I am going to pick up regular flood light bulbs and 60w led bulbs as I've read are best on this forum. Any suggestions to solve my problem would be greatly appreciated. A few pictures below.
