I weighed mine after two weeks hanging to dry and three weeks curing in jars.
For me unless buds have been over dried there's still a bit of moisture in them until they've ben cured. Curing helps slowly sweat out any remaining moisture and helps improve taste etc.
Buds loose roughly 75% of their weight between harvest, drying & a proper cure. How much they lose during the drying & how much they lose during the curing depends on how long it spends in each stage but the majority goes during drying.
Has anyone weighed their harvest fresh, dried & then cured to compare the different weights between dried & cured?
