5 Days of Darkness With No Water?

Just leave one of the cfl's on , should be fine. They are pretty safe I used them several times , hid's are a whole different story , it is still good to be cautious. I had a hard time sleeping when I was working out of state 5 days at a time with my hps running and a cab with 4 65 watt cfls, always came home and things were fine. Kinda worked out cuz it seemed my plants would take off when I wasn't around for that long.
