Terps are volatile compounds that will do exactly what volatile compounds are supposed to do: break down at atmospheric conditions. If you store them in that way, you will have shit tasting and smelling bud in a matter of days. Also, why would you want to spend months growing bud, just to leave them unprotected? Imagine if you burn something while cooking, or just make a pungent stir fry. Your buds will acquire that scent (there is no escaping a pungent batch of 'fry). You start a project and have dust or fibers floating around, it's on your bud. You carry in spider mites; see where I am going with this?
There is just too much to go wrong to justify not putting them in jars. If price is an issue, look online for whole salers. You can get jars in any size, design, and color, (and enough to last you a lifetime and a half) for pennies a piece.
