Hello, I am a new bp owner and I've searched the forum for my answers but I'm coming up a little short.

I have a 50gal tank (I know it's too big but it was given to me for free, it is modified for snakes, a friends boa was in it until she grew too big for it.) I have a lot in there for her so she isn't stressed. She is very active and eats with no problems so I know the size isn't stressing her out.

My problem is the humidity. It sits at 40% unless I mist it a lot. The lid is custom with wood and mesh. I have covered the mesh with tin foil all except the area where I have her ceramic heat emitter. I am using reptibark and I put moss around. I have a large water dish and a water dish with a sponge (I was told it would help) the bottom part of the tank has wood around it so it sits on a stand. There is no way for me to get to the glass on the bottom to put a UTH. I've heard about side mounting but I don't know if that will help.

Is there anything that I can do to get the humity up other then buying a different tank? I don't want to over mist and cause her blisters. She isn't having any problems with the lack of humidity so far but I don't want it to effect her shedding or health in the long run.

I am typing this on a phone but once I get to a computer I will post pictures of the set up.

Thank you
