i like that crystal idea that is smart man i might use that in the futureYou can either set up a drip system(PIA) set up a wick system(a bit easier and cheaper) or go to homedepot and pick up some water storing crystals. Set these in a jar over night filling only the bottom centimeter of the jar with crystals and fill the rest of the jar with water. The crystals will expand to the entire jar and then just cover the tops of the pots with these crystals. But be careful not to overwater them. It works a bit better with air pots.
