Hi John
I have used a discarded fridge thrice to hatch but the hatch did not go above 25%.That is why i want to build a custom made one that suits my taste.So i know all the basics about hatching eggs like filling a plate full of water to provide humidity ,ventilation ,turning eggs odd number of times, etc.
John, the object of using the aluminium sheet is twofold: firstly ,i want to seal the tiny holes at the surface of the plywood which can breed germs and secondly,prevent the warmth from escaping via those tiny holes therein and ensure energy efficiency.
John you said that you were able to main a temperature of 35 degrees within a 3/8 t0 1/2 inch plywood without any form of insulation.How did you achieve that feat?
Then it very likely that i can attain a temperature of 37.5 if i should use a 3/4'' plywwod.
I am i have three controllers with me, Boncun,,i would like to see the controller you are making reference to.
