Watering system

I have a bad situation. Somthing has come up and I will have to leave my plant alone for two weeks in July and one week in August (indoor CFL). Can someone recommend what I can do about watering? My other concern is that I wont be able to adjust the lights. Any help will be much appreciated.

Get a water pump, a decent sized resivoir, and an air pump.

Fill the resivoir with water and put the air pump with an air stone in the water. Make sure no light can get in the resivoir. Attach a water pump to the resivoir, and hook the pump up to a timer. Get it to run for 30 minutes a day. You can slow down the flow of water (you're a stoner, I'm sure you can figure it out) so your plants don't get over watered.

Another option is to put the air pump in the soil instead of the resivoir. That way it will he virtually impossible to over water your plants
