The rapitest 4-way soil analyzer and tester is a compact, portable, all in one meter.  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 insturctions also include a pH preference list, moisture guide, and sunlight chart.

A successful garden starts with the right conditions.  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.
