RH is the measurement of humidity in the air. When over humidified, Boveda takes humidity out of the air. If you had a lot of cigars in the humidor and they are absorbed too much water. You have to let the cigars release the excess water into the air of the humidor and then Boveda takes the excess humidity out of the air. It’s a process. The Boveda respond quickly to changes in humidity. However that is its response. The time it takes depends on the water content. You can always open the lid of the humidor for a while if the RH in the room is lower than the RH in the humidor. That will speed things up. You can always add more Boveda packs, too.
