Hi, Med ...
Why stress out on this issue for your entire vacation, wondering if you'll have any to the fruit of your labors when you get back? Like Wavels said, if you cut them down now, you'll still have some good smoke when you get back. So ... you have six days to dry them out. Just cut them, hang the upside down with a fan blowing GENTLY from across the room. Then, before you leave on vacation, just cut the buds off the stems, put them LOOSELY into brown paper bag lunch sacks and put them in your safe. When you come back, you'll have some nice smoke.
Did you take clones for your next grow? If so, what are you planning for their security and care?
Vi
