Rapitest Mini 4 In 1 Tester Model 1818
All plants have preferred growing conditions. This muli-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 effect how well plants utilize the total nutrients available in the soil. These nutrients are the building blocks the plant requires for successful growth. Successful growth can not 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 selector switch to the test being performed.
2) For pH or fertility tests, prepare a soil sample and insert the probes into the sample. Within seconds the tester will indicare the pH or fertility conditions of you soil.
3) For moisture tests, just probe the soil deep at the roots.
4) Light is measured by placing the photocell located on the top of the meter at leaf level and pointing it directly at the light source.
