Plant Light and Water Tester

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.

• Size: 4L×2½W×1½"H
• Probe length: 6"

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.
