Designed and tested with research institutions, agriculturists, and our very own Plant Doctors, our moisture meters
work without batteries and use a pF indicator to detect available water capacity in your plant’s roots, giving a more
accurate and concise picture of when it’s time to water. Easy to read with a simple color scale, blue means no need
for water while white shows it’s time for a drink. With its minimal and attractive design you may leave it placed in
the soil of your plant in between waterings or remove it if desired.

Note: Moisture Meters are offered as a supplemental tool that can be used in conjunction with manually gauging your plant’s soil for moisture. They are not a substitute for regular monitoring. 100% efficacy is not guaranteed as soil composition and other variables may affect readings.
Utilize these simple, easy-to-read moisture meters in conjunction with manually probing your plant's soil for moisture. Blue = moist soil, white = dry soil. For full instructions, click here
