I’m still waiting for my black widow egg sacs to hatch out, and I’m getting a little concerned. My lab is still a frigid cold victim of bad environmental controls in my building — 17°C (62°F) — and although I’ve got the little guys packed up in incubators, I also have to worry about very low humidity, under 30%. I’ve been shopping for incubators with both thermal and humidity control, but it’s a terrible mistake to try looking in scientific supply catalogs. $1500? For a little 0.2L box? That’s not going to do.
So I resorted to Amazon, and searched for egg hatching stuff. Here we go — there’s a mass market demand for incubators for chicken eggs, so that’s what I got.
There we go, Egg Incubator, Intelligent Incubator for Chicken Eggs with Automatic Humidity Control and Egg Turning, Temperature control, 15 Eggs Incubator for Hatching Eggs&Quail egg with Egg Candler. $40. I just calibrated it, and am waiting for it to stabilize at 30°C and 75% humidity. I disabled the egg turning, and don’t have much use for an egg candler. I think they need to adjust their ad copy to mention Spider Eggs.
I’m still keeping my eyes open for a used scientific-grade incubator, but this will do. I also think the physical plant people need to get on the ball and get the environmental controls properly balanced — my lab is a refrigerator all summer long, while some of the offices are saunas, I hear. I complain every year, but nothing is ever done.
