A slender probe gauges the soil mixture at the roots of a plant, while a light sensor on the front of the unit measures the amount of ambient light. The light-weight unit needs no batteries, so there is nothing to replace or wear out. It includes a booklet with information on light and water requirements for over 150 plants. Size: 4"L x 2 1/2"W x 1 1/2"H; probe 6"L.
