Hello, I have finally got all the things i thought that i needed and built myself an incubator! It is a 48L plastic tub (the only thing that i could buy/find ) with 6 little mini mason jars tightly sealed (to try to keep the temp steady), and a 40W light bulb in a corner. Right now i am not sure where to put the thermometer/ hygrometer, right now i have it in one end of the incubator and the light in the other, should i move it? Also i have the lid on tight, but not air tight, (there is enough room to put a 1/4 inch electrical cord through without it squeezing on it.) do i need to put air holes in the top/ sides? And if i wrap the inside with tin foil, which side should i put it on, the dull side or the shiny side? Kind Regards p.s. i don't have any eggs in there right now, I'm just testing things out.
