Can you please clarify for me regarding placement of fans and bulbs, in relation to the sensor from your Inkbird? Also, how bout ventilation holes, where, size and how many. I'm doing a dorm fridge this winter. Have everything needed except for the 12V converters for the fans.
I also mounted one of the lights below so if I needed to add humidity, I could place water near the light bulb to heat up. Haven't needed this since the humidity has been so high without it.
I just put two vent holes on the side, in the middle. I will probably put two more on the other side after this hatch.
I put the sensor for the thermostat on the shelf with the eggs, which is in the center of the incubator. I haven't really checked for cold spots since I just have the one shelf in there now. I'll adjust accordingly when I add more shelves. May need more powerful fans...
Hope this helps!
