Built my first incubator! (Pic heavy) A few questions

[Stewart_Reptiles]

Very impressive build Deborah. Gotta expand my incubator capacity next year when the bulk of my females are of age. Itake it from the photo that you don't use a separate controller for each compartment right?

Thanks , no there is one thermostat with the probe in the tub located in the middle, and I measure the temps on the top and at the bottom (the probes is in the tubs and the display are on the outside of the incubator)
