@ Wend- I'm using UTH's which give me a great hot spot of about 88F. My ambient temps would be in the mid-high 70's during the day and the low 70s at night without the heat bulbs. I was under the impression that carpets do best with ambient temps of about 82 so I as using the heat bulbs to boost those ambient temps. Can I kill the heat bulbs and stick with the UTH only? I'm definitely switching to RHPs when I move them into their individual adult enclosures next year but I have to make this one work for now.
