We use them in our cure room. Even tho the room is 65 degrees, dark, and 61% rh, we still throw a few in the CureTubes. They don't get hard or anything, and we've used some for 2 years because they don't either absorb, or disperse moisture because the environment is already locked in. But!.. its just a back up in case I forget to dump the dehumidifiers or something. Never noticed it taking away from the aroma of the weed. We have some lbs that have been curing for 6-7 months. Still squishy and pungent. I really think it gets better over time.
