What happens if I put not completely dried leaf in the kiln? Green stem and such.
If the lamina is brown and cured except that the stem is moist and green, you can raise the temp with low humidity to dry the stem and help prevent mold if your humidity where you were air curing is too high or to speed up the process to make more curing room.
If the leaf is still mostly yellow and needs further browning, you can duplicate air curing temp and humidity inside the box to finish curing the leaf, then lower the humidity to finish drying the stem.
If your leaf is still green, you can box cure the leaf in a cardboard box until it is yellow, move the yellow leaf to your curing chamber to finish curing at air cure temp and humidity, then lower the humidity to dry the stem. You could start with green leaf but you will need to vent the curing chamber so all the moisture coming off the leaf has a place to go.
If your air curing area has humidity that is too high or too low, or temps too low, you can use the curing chamber to air cure at air curing temps. It takes the guess work out of your environment.
After that, you are ready to kiln at kiln temps for aging.
