hey guys! i'm a bit conflicted. my pet store only sells one type of uth and they're the exo terra heatwave ones so i was wondering if they work well. here's what they look like.




i'm getting a ball python. i've heard the rainforest type doesn't get hot enough which is a big deal because it gets cold in the winter and hot in the summer where i live so i was thinking of using the desert one. we have heat and ac but i'm still worried! it says to only use on glass but i have a plastic cage and i'm a bit worried about that. i'm not sure if they say that for insurance or because it will actually melt the plastic. also i use newspaper so should i use more newspaper or switch to the more expensive substrate? what do ya'll think?
