Vivosun 3-in-1 Soil Tester
Checking the top inch of soil with your finger tells you almost nothing about what's happening at the roots. Before your plants even reach the soil, starting them in
Vivosun Rockwool Grow Cubes can help establish the healthy root systems this meter is designed to monitor. That guesswork is how plants end up overwatered, underfed, or starved for light. The
Vivosun 3-in-1 Soil Tester reads the root zone directly. Its dual 7.8″ probes measure moisture on a 1–10 scale, pH from 3.5 to 8, and light intensity from 0 to 2000, all on one analog dial with no batteries required.
Slide the selector to moisture, pH, or light, push the probes 2–4 inches into the soil, and read the dial after about 10 minutes. The moisture scale tells you when to water, and the pH scale shows whether your soil is trending acidic or basic before nutrient uptake suffers. The light reading helps you decide if a plant needs to move closer to a window or under a
Vivosun grow light.
At 10.8″ long and 1.8″ wide, the Vivosun 3-in-1 Soil Tester fits easily in a garden tote alongside a
Vivosun LED jewelry loupe for closer plant inspection, and it works for both indoor containers and outdoor beds. It is designed for soil only and should not be used in water or other liquids.
