Someone just gave me an old incubator....It's really just a square styrofoam box with channels in the bottom...a screen, an air thermometer, a glass top with a heating element. It's got a red light when plugged in and some red plugs for the air holes in the top. Can someone tell me what it is and if it's worth incubating in it? I can't see how I would regulate the temperature? I am going to need some thermometers and a hydrometer and a water wiggler for sure.
