This can be performed by taking the brannches and hanging them up side down so the fan marijuana leaves droop and cover the marijuana buds. During this step you need to put the branches in a cool dark place (not humid) with enough ventilation.It is good idea to check up on the marijuana buds every day to watch for signs of mold and mildew and correct the problem if it happens. After the fan marijuana leaves droop down over the flowers and turn crisp or break off easily, you would want to start trimming off the fan marijuana leaves only.
Even a better way to take off the marijuana leaves is to do it before drying the marijuana buds because it it will be much harder to cut off the fan marijuana leaves after the marijuana buds have dried. So, I recommend you to cut them off before you hang the marijuana branches upside down.The deal with this method is to dry it slowly but not to fast. If you dry your marijuana buds too fast it will make your marijuana buds smell like pine needles, hay, or taste bad. Drying the marijuana buds too slow in this first step is not a good idea ether because of mold and mildew will attack them. It's very important there's enough air circulation in the room so you can't do it without an electric driven fan.
After the fan marijuana leaves are trimmed you want to hang it up to dry again because the marijuana buds will still be moist or wet. They should still have the little inner marijuana leaves so they can droop and cover the marijuana buds. Hang the branches again in a cool dark place with proper ventilation until the little marijuana leaves and bud tips turn crisp when you touch them.5-7 days is enough i think. take a look on the picture to see how you should do it
