For me it’s a much better way to dry. My temps and humidity can literally dry bud in a day.The brown paper bag is part of the way we can control how fast the moisture leaves the buds. At least that is how I figure it.
The only fan I have is the one that is already built into the fridge that comes on every now and again to blow cold air from the freezer side.
And it becomes part of the process to let nature take its course and use the moisture coming from the larger or thicker buds to help replace the loss of moisture from the smaller buds. Eventually it balances out and everything that went into the bag is pretty much at the same level.
Then eventually you can take the bag out of the fridge and tell how far along without having to open it or handle the buds. Just the feel of the loss of weight is enough to give the feeling of how close or how much more time before jarring.
I’ve just finished drying one strain, and almost finished drying another.
My Blue Cheese Special went from the fridge to the jar two days ago, and has hovered under 64%. If the humidity is in the zone today I will start the cure.
