I use old pickle jars. Sam's Club sometimes pays off.
Biggest thing to remember is that you have to really clean them, the lids especially. I hand and machine washed them several times, let them air out for months, then washed again a few times. That brine really sticks to the inside part of some lids, so just watch out for it.
If you have crippler weed in most jars, you're just gonna smell the crippler weed anyway, but why worry about some weird smell/taste tainting your er, cheese (buds)?
Also, the jars are leak proof, as you can obviously turn a jar of pickles with juice upside down or whatever without any liquid dripping out.
If it can seal out water, it can seal out air.
