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.\u003c\/p\u003e\n\u003cp\u003eSlide 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 grow light.\u003c\/p\u003e\n\u003cp\u003eAt 10.8″ long and 1.8″ wide, the Vivosun 3-in-1 Soil Tester fits easily in a garden tote or grow-room drawer, and it works for both indoor containers and outdoor beds.
