you dont use a humidifier for cigars, you use a humidor. humidifiers put miosture in the air (you dont want your weed all wet and nasty, youll get mould eventually) a humidor just keeps the right amount of humidity in the air (like 60 something percent i believe). i think i may have heard someone mention putting your weed in one of them but idk how it would work. just a cedar box with a damp cloth or something is the very basic humidor. air tight container seems to be the best for weed as long as theres no moisture in there, if its long term you could use silica gell as long as it stays far from the weed.
