Hello BYC, I just decided to try and build and incubator for the fun of it and thought I would update everyone on this site about it, in case they are interested. This homemade incubator isn't exactly high tech or anything, but I thought since I already had some materials to experiment with, that I would give it a shot. So far for this incubator build I have a plastic tote and the wafer thermostat/element heating combination from an old incubator. At first the incubator was obviously loosing a lot of heat due to the plastic tote being thin and not insulated. Now, the plastic tote is lined with some sort of bubble wrap reflective foil insulation. Unfortunately, the incubator does not seem to be holding or producing enough heat only staying at about 73 degrees. Any suggestions to try and get more heat in this incubator would be greatly appreciated. Thanks!
