Lowering Humidity

Hello All, New the the forum and somewhat to ball pythons. I received my personal first snake last thursday and I love him (pastel) but I am having some concerns. I have been searching the threads but I must be missing my answers to the questions. First off my set up. I am using a plastic 41 qt rubbermaid locking container, with 11in flexwatt uth. I have drilled a few holes in the back for circulation. My temps are 90-93 hot, and 75 on the cool side. My humidity is 80%!!! My questions are how do I lower my humidity to a reasonable level without lowering my cool side temp further. I know 75 is on the low side so I am thinking of getting a blue light heat lamp, but summer is coming so I dont know if it is really necessary, any thoughts? Currently we are having a cold front, so that could be affecting the low temps. I want to make everything perfect for this little guy but I might be making this harder than it really is! lol

Make more holes or put a small fan by the tub to circulate teh air.

Just put some more holes on the cool side. You really won't loose that much warmth. I keep my adults in about the same size tubs. During the winter months I use a space heater to keep the ambient temp at 70, and the cool side stays around 80-even with a bunch of holes soldered in the tubs.
