Water Meter - Set & Forget

Why risk the most precious plants of your collection?

With Hoyas being particularly susceptible to root rot, this trusty device clearly indicates when to water next.

1. Insert the water meter into the pot

2. Water generously - after 15 minutes the display window will turn blue

3. Once it turns white again, it's time to give your plant another drink
