Patti the Garden Girl uses a Thirsty Light to always know when to water her indoor plants. To learn more about the Thirsty Light, go to http://www.hydrofarm.comand check out Patti's website at http://www.gardengirltv.com
But how do I know how much I should water? Does it immediately stop blinking when there is just enough moisture?
Pretty good gadget, but how I get the info that batteries are dead?
