Yes, that’s my understanding. But, they do not do well in cold temps. Fungus snd decay will start more easily bc not cured (when they actually heal skin nicks and cuts and supposedly get another skin during curing). So, your greenhouse is fine as long as you can keep the night (or day) temp above 55F - as I recall reading.I bought another half bushel of Empire apples to dry.
How do you tell when they're cured? If you can't get the temp/rh up as high as they say it should be, can you just cure them longer?
