If the relative humidity outside the incubator averages around 35%, then the (forced air) incubator should be kept as close to 50% as possible for the first 18 days right? Or do I just try to stay in the 40-50% range? Would that also change the preferred lockdown readings to closer to 70%? Incubator is located in Southern California, ~20 miles inland from the beach. I wouldn't consider this area 'desert' as we get the cool ocean breeze, but it is sunny, warm, and we have cacti. Warmer than Santa Barbara. From there, tucked away inside of a cabinet, away from drafts and windows.
