The humidity levels of the spot where you stash your herb has a lot to do with how long it’s medicinal qualities will last.
Too much moisture in the air around your herb will make it susceptible to mildew and mold like we mentioned and too little moisture will dry the trichome resin out, degrading cannabinoids and terpenes even if air temperature is optimal. Research suggests that a relative humidity (RH) level between 59% and 63% is ideal to keep your weed as consistently fresh in terms of potency, aroma, flavor, texture and color.
An RH level of 62% is thought to be the sweet spot for storing weed for smoking, while people who prefer to vape their weed are leaving it at lower RH levels closer to 54%. Serious stoners who want to keep their stash as fresh as possible for as long as possible can use products such as the Cannador or use salt-based humidity monitoring and control packs from Boveda to help you ascertain, optimize and stabilize the sweet RH spot for storing preferred strains of cannabis.
