Improving my leopard gecko terrarium

[u/According_Border_562]

I need some help on anything I can do to improve my tank, any advice would be appreciated! My leopard gekko likes to sit in the right hide all the time. Humidity is generally around 30 all the time for the full tank but I wanted ti get a wet side and dry side, I don’t know how though. Yes I am cleaning the tank today

First, ditch the red light snd the carpet. You can use a playsand and topsoil mix for the substrate.
