I color-cure my burley by just hanging it in a shed, then I leave it there to age for as much as a year. The temperature is ambient (uncontrolled), and the humidity goes up and down with the weather. A box fan in the shed circulates air. To kiln the burley, place it in a chamber @~125º F. If the source of the heat is a Crockpot (recommended), just keep the water refilled as needed. Continue for 4 to 6 weeks. Color-curing in adverse conditions requires more creative measures, such as the box that's been mentioned.
Flue-curing uses a specific temperature regimen that is discussed extensively in the threads on the subject (see the index). The leaf is yellowed at 93 to 104°F, then over the next several days, the temp is ramped in stages up to 165°F. See the discussions for that, and for useful graphs. In general, you can flue-cure most Virginia varieties, and many Orientals. Just about every other variety should be color-cured, then kilned (or naturally aged).
There is also useful info in the
Growers' FAQ (link at the top of every page).
