The Luster Leaf Rapitest Mini Moisture Tester 1810 is designed to prevent over watering. It is an ideal moisture tester for plants grown in window boxes and hanging baskets. Probe is attached directly to meter head. Includes watering needs for over 100 plants. No batteries are required for operation. For use in soil only.
Good advice from the manufacturer: Check small pots more often that large ones, they dry out more quickly. Over watering rots the roots, so do not water too frequently. Out of season, most plants only need water once a week.
How does the Luster Leaf Rapitest Mini Moisture Tester 1810 work? It didn't come with batteries. When will I know it is no longer accurate?
The Luster Leaf Rapitest Mini Moisture Tester 1810 does not require batteries. The product should be inserted into the soil next to the plant (not too closely) and it works off of the moisture in the soil. It will read the moisutre level and once the needle is stable, that will be the reading of the moisture level. Do not leave product in the soil. It should be used as needed only and promptly removed. You will know when the product is no longer effective when the needle no longer has movement.
