COLOR CHANGE FROM DRY TO WET

  • A white indicator means it is time to water your plant.
  • After watering, Sustee absorbs moisture at root level, like your plant.
  • As the level of absorbed water rises, the indicator gradually becomes blue.
  • It takes from 10-30 minutes to turn completely blue after watering, but the time varies by the type of soil.
  • Sustee’s refillable/replaceable cores have a life of about 6-9 months, depending on the type of soil.
  • Core refills are available in 2-packs by Sustee size. Click here for refill information.

HOW DOES IT KNOW?

Sustee’s patented technology measures the relation between soil moisture suction and soil moisture content, using the soil moisture retention (pF) curve. Like a plant, it absorbs water from the soil and allows it to evaporate through transpiration holes near the display window. Sustee was tested during development and proven effective by professional growers of orchids, roses and begonias.

The pF curve between 1.7 and 2.3 is the most effective water moisture level for plants. Below 1.7 root rot is likely and above 2.3 the plant starts to dry out and send roots deeper to find water. Sustee is designed to gradually turn white as the soil approaches a level of 2.3, showing you when the plant really needs water to support healthy root development and helping you to avoid watering too frequently.

HOW TO USE YOUR SUSTEE

  1. Insert Sustee near plant roots, about half way between the plant stem and the edge of the pot
  2. Water your plant after placing Sustee
  3. Sustee will turn blue to show that the soil is damp. It can take up to 30 minutes for Sustee to absorb moisture from the soil and turn blue after watering
  4. As the soil dries out, the Sustee will fade back to white, letting you know it is time to water again.
