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.
- Large sized meters cover plants in nursery pots 10” to 14” in diameter.
- Medium sized meters cover plants in grow pots of 6” to 8” in diameter.
- Mixed pack includes 3 medium and 2 large meters.
Five moisture meters per package.
Replace the core refill of your moisture meter every 6-9 months, or when it stops turning blue when watered. Core refills can be ordered here.
