Tessa watermeter L white

This watering sensor is ideal for beginners and experts alike. With it, you can find out how wet the soil is and thus avoid overwatering.

One of the main problems with indoor plants is that water stays in the pot for a longer period of time. This accumulated excess water can rot the roots of the plant and cause its leaves to turn yellow.

When you have just watered your plant, it turns blue. And when the soil is dry and it is time to water, it turns back to white.

• It is carefully placed in the substrate, between the roots of your plant. The accessory has a mark that shows you where to insert it.
• The sensor changes from white to blue when you water the plant.
• Over time, the sensor will return to white as the substrate dries out.
• You should water when the sensor turns white again.

It lasts about 6-9 months, after this period you can easily replace the inner core with the cotton replacement.
