Vacation Watering Setup, Can Anyone Help Me?

Hello All!

I am going on vacation in what looks to be the 7th week of flowering. I have a small rubbermaid setup, two containers stacked on top of one another with lights hooked up to the top lid. 184 watt cfl grow. This is my first grow, just one plant. It showed sex yesterday on its first day of 12/12 and its a girl.

What I want to know is there a simple or fairly simple DIY way of setting up some kind of Vacation Watering Set Up? I don't need it to be huge as the plant is only in about 1 and 3/4 gallons of soil. When I water lately I just use Foxfarm nutes and about a 1/2 gallon of water per watering. I water once every three days or so. I am only leaving for 5 days so I just will need one watering.

Can anyone help me? Links?

Thanks for any suggestions in advance!

Fill up a tank full of water and nutes before you leave. Get a small water pump, put it in the tank, connect it to a small tube and fix the other end of the tube on the top of the soil. Put it on a timer, and set it to run for 10 mins on day 3 of your vacation. That'll be enough time to push the water from the tank up the tube and onto the soil.

EDIT: The tank of water and nutes can stay outside the rubbermaid, and you can simply feed the watering tube from the tank into the rubbermaid.

You could always leave water in drain pans and let them bottom feed. Not good for a long time as it will get root rot but might work fine for a couple days.
