Self-Watering for Potted Plants / Beds

If you're unlucky, your potted plants can wither if they are not watered during your vacation. But with our self-watering system, you can water your plants even when you are not at home. Fill an empty PET bottle with water, attach our smart self-watering spout, and insert the bottle upside down into the soil of the potted plant or herb bed.

Some bed and container plants can go a few weeks without water if they are well-watered before the vacation; water consumption can be reduced by moving the plants away from south-facing windows and direct sunlight. But we probably all know it well; coming back from vacation and finding that one or more plants have dried up. - that's why our PET bottle adapter is the perfect solution to ensure that your plants are not over- or under-watered while you're away.

A practical watering system for plants and beds. It helps to provide water to the plants where it is needed most – right at the root.

Simply cut the tip and screw the adapter onto a water bottle, turn the bottle upside down, and insert it into the soil near the stem of the plant. You can also add liquid plant fertilizer to the water.

Suitable for thread (common PET bottles) with a diameter of 2.5 cm.

Pack contains 6 adapters
