I was wonderin what the best thermostat for an incubator would be. I will be making one out of an igloo cooler in a month or two. I was looking at the Helix Prop. Thermo and the Herpstat. You can get both at the bean farm along with the flex watt. I was leaning more towards the Helix considering that seems to be the most widely used thermostat here, but I was curious on peoples opinions on either, if one is better than the other or if they were just as good. I will be getting another one for my rack that I made a month ago. Right now I just have it on an on/off thermostat so it is hard to actually regulate. What is everyone's opinions on the thermostats?
