I know a few growers that like to have their buds dryer than 62% for smoking, so they will always have some out of the jars a few days at least before firing them up. That way they dry out a bit more (assuming the ambient RH is below 62 of course!). For long term storage, it's best to keep them in the high 50s at least to promote curing. Many plants get even better with long term cures.depending on how long I store it will determine the humidity I choose... dryer for longer term storage.
