Ok so I have my two newest snakes that I just got off of craigslist in the tubs they came in. I have no heat source in on the tubs since its about 88-90 in the room through the day and mid to low 80's at night. My temperature/humidity gauge is register the humidity at 99%. All i have in the tubs is a bowl of water and a hide. One bowl is small since the snake is small. The other is larger cause the snake is larger.
What should I do to bring the humidity down?
