Boveda packs are great.
If I overshoot my drying by a little bit these things make it no big deal. They also keep my jars at exactly the same humidity.
So if I’ve dried correctly my buds are already at 60-62 and they won’t need a boveda until I notice the humidity falling in the jars to, say, 55%
I’ve never used them to lower humidity levels, just maintain and bring back up.
Well worth the $2 to me
