Hey all, so I have everything except my dehumidifier. Using inkbird controllers itc-308 and ihc-200. I just have leads clamped in door at moment fridge only drops 1 degree low but goes 2 degrees above(cermaic bulb). Do you think my heater is maybe underpowered or is this 3-4c fluctuation ok? I also noticed quite bit condensation on walls is this ok? Finally is there such a thing as safest place to drill hole for wireing access?
