Seeing as it takes 3-4 weeks for a decent cure I'd say you're SOL for going that route. But curing isn't really necessary...just get it dried out and jarred before you take off for school, even if it means being a day or two late getting back. A thorough drying is needed so mold doesn't set in during storage but it can be put off if you get them in jars after drying as much as possible then getting them into a refridgerator (I like to use the bottom shelf of the fridge). Then when you get back you can hopefully finish the cure/drying then. The cold should put everything on hold and a sealed jar will keep them from getting overly dried as there'll probably be a little excess moisture in the stems...so in short, dry them as much as possible, put into canning/fruit jars and store in the fridge until you can get back to them.
