Yeah, there is a pretty decent debate on that. Some people just chop and let hang dry with all fan leaves still attached. It slows the drying process down a little (One arguement is that this increases flavor). Some like to Do all pruning at harvest. this will speed the process up a little bit. I do a combination. At harvest, anything that can be pulled off, I pull. let hang for a few days, then remove the wilted fan leaves. Then hang a few more days. then I trim the buds up completely (Before the buds are feeling very crispy). let them hang again, until they start feeling a little crispy. Then I put them in a sealed 5 gallon bucket for a half a day-a full day to let the moisture even out....Then hang them again. repeat to slow the process down a little, and allow the buds to dry evenly.
