Might seem like bit of a strange question but I was wondering what's the best way to keep moisture in your weed? I'm getting a few HG Ozs tomorrow and the people that grow it leave a bit of moisture in it, I presume to keep more weight in it. Last time I got it I had 28gs in a paper envelope, the next day it weighed closer to 27. So I'm just wondering if anyone has any tips to keep the little bit of moisture in it so it doesn't loose a load of weight. I presume keeping it in plastic rather than paper would help but are there any other little tricks? I've heard of other people having similar problems, I think they're getting it off the same person/people. Also sorry if it's the wrong section but I couldn't really see anywhere else to ask.
