I'm going to have to leave my plants (about 3 weeks old now) for about 10 days while I go on vacation with my family. Can anyone think of a good method for watering them? Keep in mind I'm kind of low key, only growing 8 plants in my closet; plus budget could be an issue.

check out how to make a wick type setup with another pot below the soil pot. the second pot should be full of water so the rope/wick can bring water up into the soil

dude jus mulch your plants and then water them..the mulch helps soil stay moist for a while..
