i have a friend that used the seal-a-meal thing. it seemed to work for him but i don't think he is going to be using this method again. he dried his buds out quite a bit and then used the seal-a-meal, and it crushed his buds into a bunch of dust. it smokes just fine but it looks like a bunch of shake you would find in the bottom of a bag when you are done. I would be interested in the vaccume jars though. would it be a good idea to put it in vaccume jars and then put it in a freezer?
