How to Probe

How it works

Step One
Push the GrowProbe into the bottom of the pot, and pull it out gently
Step Two
Rub the soil between two fingers to check how moist the soil is
Step Three
Ideal watering times vary between plants, seasons and enviroment, use this scale as a general guide only

The Growprobe is best used on pots 12cm (diameter) and up
Push the probe into an empty space in the pot, avoiding the base of the plant
Avoid using it on root dense plants such as Bonsai. If it doesnt go in easily, don't push it
If the GrowProbe is used on a diseased plant, be sure to sterilize the GrowProbe after using to avoid transmission to other plants
Best suited for soil based media as the notches aren't able to pick up larger materials such as Bark
Unless the soil sample is obvious that it is either wet or dry, feeling the sample between two fingers is always the best practice, as going off colour alone can be deceiving
In larger pots, probe several times in different areas to confirm the soil moisture
