Going away

I'm going away for spring break leaving nobody to water my plants... I don't have some fancy watering system, I do it myself. I will be gone for a week what do i do? The plants are between 4 inches and 3 feet at the moment. Do I just overwater them before i leave? or do i switch the lighting to make a shorter daytime?

id try to get a real good friend ( someone you have known your whole life) to water them while your gone

fill up a 5gal bucket of water, poke a SMALL pinhole in the bottom, hang it up , theres your "drip" for you "trip"
LOL, i dunno man, seen that on a movie once, worked or him,

1 week isnt too bad, just water them well before you leave. im sure they go for more than a week sometimes in the wild.
