Well I decided what the heck, why not try to build an incubator? Miss Prissy's design seemed simple enough and the directions were easy to follow... so low and behold I have a homemade incubator! However, I can't seem to get the temp high enough. Temps are hovering around 99.1F, however the humidity is about 72% so I've opened up ONE vent hole to try and drop that a bit... but I'm sure the temp will drop more as well now. I pretty much built it "to spec". The only "major" variation is I have a fan hooked up to a 5v adaptor instead of 12v. Only difference is its not quite as forceful, but in such a small area I wouldn't think it would make a big difference? I don't know if my cooler is a littler larger? It's about 10" x 20" at the bottom. I've got a 25 watt bulb in there right now and the thermostat at it's lowest setting, however its never got hot enough to trip the thermostat off, so that's not the issue. Should I, or could I, up the wattage on the bulb to get more heat? BTW... the incubator is sitting in the living room. No direct sunlight or drafts. Room stays about 72 F. I even keep a piece of styrofoam over the glass window to keep more heat in. What else can I do?
