The Rapitest Soil Moisture Meter measures water at the root
level – where it matters! No longer will you risk over watering
a healthy plant just because the soil near the surface is dry –
or under water because it appears moist. Ideal for houseplants,
window boxes, patio tubs and hanging baskets. Includes a
watering guide and special needs table for over 150 plants.
Batteries NOT required. DIRECTIONS FOR USE: Step 1: Simply
insert the probe deep into the soil of any pot or planter. Step
2: A tiny amount of electrical energy will be generated by the
moisture, which will cause the meter needle to register moisture
levels from 0 to 10. Step 3: Remember that soil may look and
feel dry on the surface; however, there may actually be no need
to water where it counts. For use in soil only. Do NOT use in
liquids.
