  • Moisture: Push switch to the left. Insert probe deeply into soil reaching root level. Keep probe close to plant. Note moisture level and refer to the chart listed on the packaging for your plant’s watering needs.
  • Light: Push switch to the center. Facing the light source, hold the meter next to the plant. Avoid touching sensing element located underneath gauge. Note the light level and refer to the chart listed on the packaging for your plant’s light requirements.
  • Soil pH: Push switch to the right. Insert probe deeply into soil. A pH reading greater than 7 is alkaline, a reading less than 7 is acidic. Most indoor plants prefer a slightly acidic soil with a pH between 6.5 and 7. Soil that is highly alkaline will cause the leaves to lose their color and stunt the growth of the plant. Acidic soil will cause the leaves to wilt and drop.
