This watering sensor is ideal for beginners as well as for experienced plant growers.

With this accessory you will know how wet your plant's soil is and avoid overwatering. It changes to blue when you water your plant, and back to white when the substrate dries out.

One of the main problems with indoor plants is that water stays in the pot longer. Overwatering can rot your plant's roots, and cause its leaves to turn yellow.

1. It is placed carefully in the substrate, between the roots of your plant. The accessory indicates where to insert it with a mark.
2. When you water your plant, the sensor changes from white to blue.
3. Over time the sensor slowly returns to white as the substrate dries out.
4. You can water again when the sensor is white again.
