Plus light meter

Take the guesswork out of providing optimum conditions for your plants. This new 4-way meter instantly analyzes soil and moisture, plus available light, factors that are critical to good plant health. With 3 probes, the Analyzer reads and reports moisture in the soil at the plants’ roots, the soil pH on a scale of 0 to 9, and whether fertilizer is needed, reading “too little”, “ideal” and “too much.” Treat your plants to added nitrogen, phosphorus or potash as needed. Switch to “light meter” to read the amount of light your plants are getting. Compact, durable, permanently calibrated and simple to use. No batteries ever needed.
