Hey Oscar, yup, it's a 30 second quick wash method. Really easy and if you got a hot spot or really small heater to speed up the alcohol evaporation, you can do it in a morning (well the process takes about 3-4 minutes to do, but you have to wait for evaporation.
I wouldn't have thought the remainder would be good for much, plus it has the remains of the alcohol through it. I guess you could probably bake with it but I just toss it away....
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
