Why is 50F in the summer cold but 50F in the winter is warm? Why can I run my bigger styro bator at 75-80% with no condensation but many hatchers with a mini or cooler bator will have swamp like conditions at the same percentages?
Don't get me wrong, it's a good question, I've pondered it myself and have never found a solid answer. I believe it has something to do with the material the incubators are made from and or the amount of space. I can't tell you the science behind it and not going to pretend I know. But I know this: the few people I know that use cabinet incubators tend to run humidity in the 50's for successful hatches, and don't have as much success with lower humidity methods. More than 90% of regular styro bator hatchers that I know (which is a lot greater than cabinet granted,) have found greater success (except in the cases of high altitude) with a low humidity method after having very bad hatches with the bator recommendations of 50% or higher. For some reason in a big majority of the cases I've seen 45%+ in the styro bators prevents the eggs from loosing the amount of moisture it needs to. Could it be the air in the smaller area at 50% is more dense than a larger area at 50% preventing the moisture from being drawn out? I would assume that if you were enclosed in a small area at 50% (with the same equivelant air circulation,)that it would still be harder or feel different breathing than in a bigger area at the same humidity level. I know the smaller the bator the less humidity it takes to produce condensation. Also I have to question, say your cabinet incubator is made of wood, does the wood draw in some of the moisture from the air? It would still attribute to the humidity, but the moisture would be in the material and not in the air? Styro bators don't absorb moisture, it hangs in the air. I honestly don't know the exact whys. I just know from what I have noted, for some reason, the differences in bators do make a difference as to what will work for you versus what might work for others.
