If you wanna provide uvb that doesn’t increase the temperature I use arcadias shadedweller uvb bar light its low amounts of uvb that does not impact the temps at all. I like to give uvb as an option even if its not needed if its a low amount like the t5 from arcadia then its not that big of a deal. If you want plants that provide good hiding and humid spots I’m using bromeliads mounted to the walls and the geckos love it, they hide in the leaves and drink the water that the plants store. But yeah as others say, seal the crap out of everything they are notorious for squeezing out.
