There was a gormet food place where I used to live and they sold these coffee jars that had a pump to suck all the air out of thid container they sold, and they worked great. I never was into selling any of my bud, and I would keep it in these air-tight jars for up to 6,7,8, maybe 9 months or even more and every time I smoked it, I got ripped out of my mind. Meaning that age or sunlight did not play a part in the potency of the weed, at least in my case here in Oklahoma.
