I'm new to this too. But I think you still need another hide for the cool side. Its my understanding that bp's will not thermoregulate properly if they don't have a safe hide on both sides. I think you could go with a smaller size of the plant tray if you don't feel like you have enough room for two hides. Someone recommended hamster igloos to me. That large water dish will help with humidity. My snake doesn't like it when I mist either X).
