I soak them in luke warm water once or twice a week. should i do that more often?? and i feed them mustard and collard greens. and everynow and then some the that fancy lettuce. but never iceberg. I put them outside as much as possible. in houston though i think it gets to hot outside, cuz after a few minutes it looks like their sweatting like crazy. should i put them outside more often anyways?? thanks.
