How long does weed keep?

in a mason jar it'll last forever.

I keep them in Mason jars, in the fridge ... I don't freeze, as I suspect that might make the trichomes snap off, etc ... I just ordered a cheap vacuum food-sealer, that seems to be the hot trick these days .... just don't suck them down to the point of crushing the buds ... :smokin:

shit weed like wine it get better with age as long as it seeled

One month will be fine. If you want to keep it fresh though (better taste?) just put it in the freezer.
