I'm going to building my first snake tub for my first snake this weekend. And I know the humidity must stay above 80 percent, but how hard is this to maintain? I am going to buy Cyprus mulch, and I also have spaghnum(sp) moss to make a humid hide with. Is it okay to use the moss outside of the hide to keep up the humidity? Also I am planning on few ventilation holes to keep the humidity in. I also bought a large water dish. Which is the best to keep it on for humidity?
