I guess another issue would be, even if the ambient temperature was acceptable now, what do you do in the winter. I know S. Florida stays relatively warm during winter, but it can still drop well below the acceptable temperature for the snakes. Do you think your home would have an acceptable temp then and you'd bring them inside and regulate with a UTH?
You also have a lot of insects down there. Not sure if those could become an issue.
I keep her inside in the winter. I Dont think insects should be an issue. Screened in patio, screen top tank, and the top is also partially covered w a pillow cloth.
