aright heres whats up. it will last you all summer IF you:
1. keep it in an airtight container (glass preferably).just get somethin like an old glass peanut butter container. anything thats glass with a screw on lid pretty much.
2. keep it in a dark place.
3. open it every couple days for 10 minutes to dry it out.

if you follow all these steps, your weed should last you well through summer.
