Get your hands on some 2 liter soda bottles. Fill these with water, and invert them into the soil, right by your plants. 2 or 3 bottles by each plants should keep them watered for a while.
Good luck!
You can purchase those watering globes to help supplement their water while you're away. However, dyzel's soda bottle idea works on the same principle and is much, much cheaper!
These sort of thngs don't last a long time, but they will definitely help your plants during their week: Watering Globes from Amazon.com
good heavy duty trash bag full of water... Poke a couple tiny holes on the bottom and sit it right at the base of the plant. It will take a couple days for it to fully deflate. That will buy you some time.
its in the middle of the woods so i cant do a hose thing. would the 2 liters just all drain on the first day tho? its also very hot and humid lately and they get droopy after 3 days
