Any food will go bad in a ziplock bag, but the shelf life is different. Dried cannabis will generally stay fresh for a year or more when stored in a ziplock bag. But over time, marijuana loses more and more of its THC. On average, about 10% of THC is lost every year.

What are the ideal storage conditions for cannabis?
Proper temperature, humidity, and light.

1. Not too dry or too wet, too dry will easily become brittle and broken, too wet will easily mold. Humidity should be kept between 54%-63%;
2. Store in a dark place, away from direct light. weed can be kept for more than 1 year in a shady place.
3. Keep it in a cool setting, not your fridge or freezer – too cold will suck the luscious moisture from these leaves.
   

Should weed be stored in airtight ziplock bags?

Usually, zippered plastic bags made of polyethylene are not suitable for storing marijuana. The reason is that gases, moisture, and microorganisms can penetrate polyethylene. Causes cannabis mold. Unless it is a special customized functional bag.

Let me talk about the following ziplock bags suitable for storing cannabis:
