Terracotta Irrigation Sensor

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 a dark brown colour when you water your plant, and returns to a light brown colour 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.

• Place in the substrate carefully, between the roots of your plant. Insert the whole accessory into the substrate, until the head of the worm is just above the top of the pot.
• When you water your plant, the sensor will change from light brown to dark brown.
• Over time the sensor slowly returns to a light brown colour as the substrate dries out.
• You can water again when the sensor is light brown again.
