Finished, finally! I got my DIY incubator up and running today and need some opinions. It is a small 6 bottle wine cooler converted into a bator. Has a built in fan and glass door. I taped flex watt to the bottom and it holds 2 6 qt sterilite tubs. In the tubs I used moist sand (I looked in every local hardware store and all the perlite/vermiculite has miracle grow in it) with light diffuser on top and an accurite thermometer/hydrometer inside. I have a hydrofarm thermostat plugged in and armed at 89 degrees. Ok now to the point. At first I had the T-stat probe outside the egg tub and the egg box got up to about 96 degrees. Next I put the probe inside the egg box and so far this is what I have - T stat reading 89-89.6, humidity inside the egg box 99%, and temp inside the egg box 90 degrees. SO...... would you lower the T-stat temp, where do most of you keep your T-stat probe, is there any reason why sand would cause an issue, is 99% humidity okay? Any other comments?
