Description
Keep your plants hydrated while you're away: no pump, no power, just gravity.
This is a passive drip irrigator that screws directly onto standard plastic water bottles. Once attached and placed in the soil, it slowly releases water into your pot by the small holes on the body, providing continuous and controlled hydration for your plants over hours or even days.
The design is compact and stable, thanks to the pointed tip with a helicoidal blade that grips the substrate.
The dripper includes a small adjustable screw on the side nozzle, controlling the air flow to the dripper, allowing to pause the drip.
