Keep the soil moist. If you are worried about them drying out while you are gone punch some holes in the cup sides towards the bottom and place the cups in a bow or pan with an inch or 2 of water in it. Don't leave the lights too close they may grow and inch or 2 while you are gone.
Good luck and keep posting!~
