Just sharing some pic of a incubator we designed and have put to use.
Bottom starts off with PVC pipe fitted around the bottom and wrapped with zoomed heat cable . Next level is egg crate and that stainless steel water pans 3 of them. Middle pan has a air stone in it attached to a air pump. This does a awsome job of adding fresh air to it and raising humidity.Right above the water pans are 2- 2" cooling fans attach right above pans and below next level. As the water is heat and humidity is released into the air the fans keep it consistant throught the chamber. Next level is another egg crate and last is the tubs. Each polycarbonite tub has rubber bumpers on it and glass tops allowing about 1/8" air flow inside the tub. We use no substrate in this design and hatching has been excellent with many types of reptiles. Last to finish it off is a 2 section glass top that fit around the rim of the incubator. This allows us to view the eggs and not affect the inside temps by opening the incubator up whats so ever.
