I will open the plastic bags every other day for the first week and check the humidity and after the first week I check every day. You may find that swapping in new paper bags may be needed, or just leaving the bags out of the plastic to exchange built up humidity, just don't forget them, LOL
During the summer when it is too humid in the house, I use the paper bags inside plastic bags as well, one addition is that I also run a bunch of the paper bags thru a shredder and put that into the bags with the buds as well to help absorb moisture more surface area to absorb moisture.
