First let me show you the high tech state of the art incubation system I used A simple rubber maid container sitting on a homemade heated ceramic tile, temperature controlled by a dimmer. Sitting on top of a roaster that is stored on the refrigerator, since October. There are small holes drilled around the top edge just below the blue top for air transfer.The eggs are sitting on moistened perlite. I didn't set the heated tile directly on the refrigerator. Here's 2 pics of their quickly setup enclosure. It's small but so are they. This is basically the same setup that I used with Alex, no hot incandescent light or che used. Again I am using my heated tiles, 2 below, a 12 inch on the left side and a 8 inch on the right side. The raised tile on the left side is 8 inches, setting on old empty glass spice jars. It is the only only heat source inside the enclosure, The bottom 2 tiles are not touching the glass just the plastic frame. The temp readings at surface level are 91 on the left side and 82 on the right side and moisture is between 71 and 85. Lighting is Reptisun 5. The substrate is aged cypress mulch that I screened thru 1/4 inch hardware cloth. No full time water bowl. The light is 20 watts and all 3 tiles together are only 32 watts, 52 watts total usage.
