I've been reading and studying about incubators to put capped off queen cells in and let them emerge into a cage. I building it out of 3/4 inch birch plywood and am putting 1/2 inch Styrofoam insulation that is foiled backed inside. It is 16 inches tall by 23 inches long and 15 inches wide. I bought a heater from incubator warehouse 100 watt fan forced with sensor and it's a digital thermostat. I got a pan to keep water in the bottom and a thermometer and hygrometer to keep up with the temperature and humidity. I will keep the humidity around 80-90% by placing a pan of water with a sponge in it to act as a wick. The door will be in the front with a double pane glass 10x12 so the void between the two will act as an insulator. I will start adding pictures tomorrow on the incubator.
