Storing Bud for a long period of time, HELP!

Ok, so I got this ounce of some dank, I need to store it while I go away for about 3-4 weeks. What I did was have it in a mason jar stuff then in a brown paper bag and stuff in a drawer.

Will this work? Stay the same quality. What could I do?

Thanks.

Dark, cool and not moist is the best and as little air in the jar as posible.
