Detailed pH preference list
Light needs chart
All plants have preferred growing conditions. This multi-purpose meter allows you to monitor the conditions of soil pH, soil moisture, light intensity and total combined nitrogen, phosphorus and potash levels.
The soil's pH level will affect how well plants itilize the total nutrients available in the soil. These nutrients are the building blocks the plant requires for successful growth. Successful growth cannot be achieved with inadequate or improper light amounts. And even if these three key growing conditions are ideal, a garden will not thrive if over or under watered.
Easy to Use
1. Slide the selector switch to test being performed.
2. For the pH or fertility tests, prepare a soil sample and insert the probes into the sample. Within seconds the meter will indicate the pH or fertilizty conditions of your soil. Check your results against the detailed pH preference list inside, or determine if a fertilizer application is required based on your readings.
3. To determine moisture level, just probe the soil deep at the roots to measure whether watering is necessary. The moisture guide (included) will help you know if your soil is sufficiently moist.
4. Light is measured by placing the photocell, located at the top of the meter, at leaf level and pointing it directly at the light source. By checking the chart inside, you can tell if your plants are receiving the necessary light.
