Summarize the following:
In cooler periods, open the doors of the barn or shed during the day to bring in the relatively warmer outside air. In warmer periods, and if your leaves are drying too fast, close the doors during the daytime hours and open them at night to bring in the moist night air.  You may need to use a humidifier if your leaves are drying too quickly.  If you dry your tobacco in your home, be sure to mind the temperature and humidity to avoid drying the leaves too quickly. An air-conditioned home would probably be too dry for air-curing tobacco.  Leaves that dry too fast may remain green. As they dry, the leaves will turn yellow, then a kind of orange, and finally brown. (The shades will vary somewhat depending on the kind of tobacco leaves you’re using.) Depending on environmental conditions, the process will take between 3 and 8 weeks.  When the leaves are brown and the edges have curled slightly, the process is complete.  The dried leaves will be slightly sticky, and they’ll have the feeling of very thin leather. They should still be pliable, not brittle.  The dried leaves should have a slightly sweet smell from the curing process. When the tobacco is ready, carefully peel the leaf away from its stem. You may use it immediately or store it if you want to use it later or let it continue to ferment.  Stems retain moisture and may increase the chance of mold in storage.  Tobacco leaves are ready for smoking or storage when they’re brown and pliable, but not too brittle. If the leaves get too brittle, you can moisten them with water from a spray bottle. Almost magically, they’ll regain their pliability with a little moisture. You can store the leaves in a humidor or even in a plastic bag. If you’ve moistened brittle leaves for storage, be sure to pat them down with a paper towel so there aren’t any water droplets on them. This will keep the leaves moist but reduce the chance of mold developing while they’re in storage.

Summary:
Control the humidity as your leaves dry. Monitor the leaves to know when they’ve dried enough. Remove the stems from the leaves.
