Storing cannabis properly will help preserve quality and maintain potency. Keep them in a dark and cool environment, and store your flower in an airtight glass jar that is as airtight as possible. The general rule when it comes to storing marijuana is that glass is best, and you should avoid metal or plastic. While plastic and metal can be used in the short term, they will start to affect aroma and flavor after a while.

Glass jars are a well-tried and accepted method that is popular with cannabis growers. On the one hand, exposing cannabis to too much light or outdoors will dry it out and turn it into dust, which you can still smoke but won't be as effective as properly stored marijuana.
