Newly planted trees. Raised bed Vegetables. Potted houseplants. All of them depend on you to ensure they have enough water to thrive. How much is enough? This sturdy, easy-to-use meter needs no batteries. Simply insert the 20cm (8") probes near the roots to get a surprisingly accurate reading of the moisture! Keep your plants happy without overwatering.
The second function on this 3-way meter is a soil pH tester. Collect clean stone free soil from below the surface. Make sure the probes are clean and dry, then insert 4-5" into the sample for 60 seconds. If the soil is too dry, dampen it. The pH reading will give you a good idea of how alkaline or acidic your soil is.
The third function is a photometer to measure the light intensity.
Note: Proyard 3-way meter is not waterproof; only the probes can be submerged in liquid.
