Wrap it in foil in the short term
Aluminum wrap protects from light, heat, and air -- which makes me wonder why we don’t use it more. As a short-term option, it’s a fantastic option if you’re planning to only open it once, much like restaurant leftovers. If babied, unlike restaurant leftovers, it will last for weeks untouched outside the refrigerator. But when manipulated often, foil can bunch up and poke at trichomes, especially when carried.
Keep it moist, but not too moist
If you don’t have access to a humidor (more on that later), don’t be afraid to throw an orange peel, carrot, or wet cotton ball into any container you’re storing weed in, but don’t bother unless your stash is already drier than you’d like. Excess moisture is almost worse than powdery weed, as mold or bacteria spreads quickly. Think of these as re-moisturizing options, rather than preventative measures, and you’ll be fine.
