Hi Daveroller, well I use to cure my bud by putting it into a shoe box, and slowly over a couple of weeks removing the box lid more and more each day and then just jarring it. I would suggest something like that rather than freezing it before it's cured. Just make sure the box is not in a really dry place, 50% RH or around that. With a small gap to let air in that will produce a nice cure on it while you are away. If you are worried about turning the bud you could put the bud on a rack inside the box so there is air above and below it.
Funnily enough I have been thinking of a similar thing as I may have some girls to chop before I go away as well.....timing can be a bummer sometimes!!
Peace, DST
