I dont know if this has already been shared, but here it goes. This is an idea that is currently being used to incubate my bearded dragon eggs. Get 2 stackable containers such as rubbermaid or the sterilite. In the bottome container put about six inches of water. Use a 150w submersible heater that has an adjustable temp guage on it, place the heater in the bottom of the water and hold it down with the supplied suction cups. Next take the other sterlite and put inside the one with water. When adjusting the heater set it a couple of degrees lower than the temp you desire inside the incubation chamber. The humidity is kept high but can be maintained by fanning with the lid. Cheap easy and works GREAT.
