The brown paper bag with cause a rapid dry and you will lose a lot of your terpenes, low and slow is the way to go with drying. Brown paper bags are great for sweating cannabis after it is dry but I would not recommend doing the whole dry in bags. If you have ever noticed your buds re-hydrate after you buck them off the branches when they look dry this is because the inner moisture of the stems and buds has not been pulled out. Paper bags are best for this step on a small scale and will help pull out that inner moisture and get buds to the perfect moisture levels before going into a container for curing.
