If you haven't left yet or haven't decide what to do while you're gone this is what I have done in similar situations_ If they are ready to harvest and dry and I'm going to be gone for 5-7 days I water them well the night before I take them down. Then I remove all the fan halves and any secondary leaves and cut the branches off at the base where they join the "trunk". This keeps them from drying too fast and they should be ready to cure when you get back. But this schedule works for me because I have dried and cured about 6 times in the same room and know that if I keep the humidity in the 50% range and the temp in the 68-72 range that it takes 5-7 days to dry just right.When I hang them I make sure they don't touch and never had problem with mold.I also have a fan aimed at the opposite wall, turned on low, just enough to keep a little air circulating in the room. If I have to leave before they are ready to come down then I water them very well before I leave. If they are in 5-7 gallon pots then they won't start to dry until the 3-4th day and if they don't get any water after that for a few days before harvest then they will dry a little faster when you get back and cure once they are ready. I also have a gravity feed watering system that I can set up that drips water into the pots 4x day_ about 32 oz.total which lasts about 7 days for 5 plants. Like a constant drip system does. They just drain into the buckets and out the bottom. Whatever you do i hope everything works out and you don't stress about it while your out of town!
