I think you could. Like you said, it will get dry, but you can fix that by adding a moist paper towel or some lettuce to the jar. Also, I'd recommend putting the weed in the freezer.

Thoughts?
dannyboy420 Reviewed by dannyboy420 on . does weed ever go "bad"?? just wondering... COULD i keep weed in glass jars / containers for like... 6 months w/out it losing its potency? i'm guessing the only real bad thing that can happen is that the weed will get really dry.. but i can deal with that.
