a. While testing moisture, the temperature of the soil will be displayed on LCD
at the same time.
b. Press ℃ / ℉ OFF button to set the unit of temperature is ℃or ℉.

growth (Some plants need more light
than others).The unit has graduated the environment light and display according to
intensity, which can offer reference for your plant

growth. Here is the list:

●INTERPRETATION OF PH VALUES OF THE SOIL:
Extremely acid or alkaline
is
important factor for restricting plant

and feature. Most plants can ’ t grow in the soil which is extremely acid or alkaline.
By testing your soil, the user can choose plants with the correct PH or adjust PH
more accurately, effectively and economically.
PH ＝7 indicates a neutral soil
Below PH ＜7------acidic soil
Above PH ＞7------alkaline soil
Here is the list of PH value of the soil compared with acidity and alkalinity:
Out of range Out of range
Increase in acidity Neutral Increase in alkalinity
Lo 3.5 4.0 4.5 5.0 5.5 6.0 6.5 7.0 7.5 8.0 8.5 9.0 HH
Look up the PH reference list. If the PH reading
is
lower than the PH range
for your plant, then you can add lime to increase PH. If the PH reading is higher
than the PH reference range for your plant, then you can add chemicals and organics
to reduce PH.
Tips: Raising or lowering PH
is
not an exact science and most plants have a
reasonably wide PH tolerance.
A
majority of plants can survive on a PH around 6.5,
some need a particularly acid or alkaline soil.
