no idea on the self watering pots, but for the cost of 2 of their $38 self watering pots you can purchase a drip irrigation kit with enough drip emitters and hosing to water 25-50 pots. If you want to get even more lazy (nothing wrong with automating things ;-) you can add a fertilizer unit into your drip system for around the price of another self watering container. Want it fully automated on a timer? Add the cost of one more of those self watering pots.
