ABSTRACT:
An add-on apparatus for feeding container plants. The apparatus contains a battery-powered pump which is designed to pump feeding solution out of a user-supplied container. The apparatus also contains a moisture sensor which is embedded by the user in the growth medium of the plant. This sensor controls the operation of the pump. On the condition of low moisture level, indicative of the need to feed, the pump operates for a controlled duration thus delivering a controlled amount of feeding solution to the plant.
