Hydro Farm 3-in-1 Soil Analysis

This handy, fast-reading instrument features a probe for measuring humidity, another for measuring pH, and a light sensor for measuring light intensity.

• Durable and easy to use, both indoors and outdoors.
• For moisture measurement, insert three-quarters of the probe length into the soil.
• Moisture measurement is recorded on a scale of 1 to 10, with 1 being dry soil and 10 being wet soil.
• Three color zones help you interpret the result, depending on whether the plant prefers rather dry or rather moist soils.
• To measure light, place the light sensor near the plant, pointing it towards the light source.
• A reading between 0 and 500 indicates low brightness while a reading between 700 and 2000 indicates the presence of high brightness.
• To measure pH, take a soil sample and make a slurry by adding distilled water.
• Insert 10-13 cm of the probes into the mixture and hold them there for one minute before noting the measurement.
• Do not use in the rain or in wet conditions, as only the probes are water resistant.
