Easily spot when indoor plants need a splash of water with this handy indicator stick. Push it into soil and leave in situ all year round. While the display shows blue, moisture levels are fine; if it turns red, it’s time for a top up.
Once you’ve watered, the indicator will change colour from red to blue within 2 hours. For accuracy, we recommend replacing your indicator every 12-18 months.
For indoor use only.
Key features:
- Simple colour changing indicator
- Helps avoid under or overwatering
- Remains effective for up to 18 months
