Heating vertical enclosures

[akane]

Wow did I stir up some drama lol I was told there is no way to heat a vertical glass enclosure with only the door as the mesh without heating the room. For humidity and simplicity of acquiring the enclosure I would rather leave it that way. I know it's mostly a snake forum which would make this a lot easier since the inside top would be safe to use but for climbing lizards that can use glass is there a way to heat a solid walled vertical enclosure?

Slightly different topic I got in a disagreement if plants need any of the uv light from a fluorescent bulb. We do aquariums with glass tops or glass/plastic covers on the bulbs all the time even for bog plants and most of the full aquatic plants would still grow out of the water in normal conditions with no trimming, I have several temple plants doing that, so while I know it's a different concept aren't we blocking all uv light there and still growing plants? Shouldn't the terrestrial plants grow without any uv?
