The process of preserving cannabinoids and terpenes in cannabis buds by placing them in airtight containers after harvesting. Curing is distinct from, and done after, the drying phase of harvesting.
How to cure marijuana
Curing is often overlooked, yet it is an important part of the growing process.
At harvest, cannabis plants are cut down and dried to remove moisture from buds. Once buds are trimmed and dried, they need to be cured to preserve flavors and aromas.
To cure, buds are placed in an airtight container made of glass—such as a mason jar—ceramic, metal, or wood, but not plastic. Relative humidity in the jar needs to be between 55-65%, and jars also need to be in a dark room or covered because UV light can degrade cannabinoids and terpenes.
Jars need to be “burped,” or opened for a couple of minutes once or twice a day, for the first week, and then once every couple of days after that. Burping allows moisture to escape and oxygen to replenish inside the container.
Curing usually takes between two weeks and a month, but buds can be cured for longer.
