Boveda is ideal for storing and curing (aging) herbs that have already been dried. While Boveda is effective in moisture removal, the standard method of hanging in a dry environment is most effective. When you feel the plant is close to the intended moisture content for curing, Boveda will do the fine tuning for perfect long term storage. Grow it, dry it, package it with Boveda.
3rd party testing has determined the ideal storage humidity at 59-63% RH.
It's impossible for Boveda to humidify beyond the RH on the pack, so there's no such thing as using "too much". It is recommended to use the largest Boveda that will fit in a given container and 2-4 60g Boveda for a one gallon or larger container.
