I'm trying to make one out of styrofoam. I am feeling pretty good about tweaking the temp to get it right. I'm just not sure where to place the thermostat. In all that I see it is either lying there or connected to the side of the cooler. In the hard plastic coolers I see screws, but I just don't know how well a screw would work with styrofoam. Plus I've heard putting the silver side closest to the light bulb is best but then the setting of the thermostat is between the thermostat and the wall of the cooler and is impossible to reach. any tips?
Oh, and I'm trying to calibrate my hygrometer, but it just isn't seeming to get above 52%. I'm thinking that it can't be THAT far off. In those tests I've been doing the 1/2 C salt, 1/4 C water. That has left it pretty soupy. From other videos I've watched, it seems that it shouldn't be that soupy. So for this last one I've done (it's currently in the bag, has been there almost three hours) I poured out the extra water. It's up to 56%. Am I doing something wrong or is my hygrometer terrible?!?!?!
Have you tried youtube? If you look for home made incubators on youtube will find lots of videos that use styrofoam.
