To avoid them from doing this again, you can place the containers in something similar to a kiddie pool, if possible.... This way, you water them until you have about an inch or so of runoff collected.... With the bottom of the pot submerged, the roots will suck up any and all moisture needed.... However if you do this, do not let them go for more than a day with the bottom of the pot submerged....you still want that wet/dry cycle....

Or you can just fill the kiddie pool, or similar setup, with like 5gal or so to see if that is more to their liking....just throwing ideas out to ya....
