Keep your plants hydrated while you're away: no pump, no power, just gravity.

What is it?

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.
 

Flow control screw

The dripper includes a small adjustable screw on the side nozzle, controlling the air flow to the dripper, allowing to pause the drip.

ATTENTION the screw is really tight: before using it fully tighten it to the dripper and then adjust it according to your need
 

Supported water bottles 

Not all commercial bottles are supported, the best thing is to print it and try it on different bottles. The dripper have been tried on European PET bottles. The bottle used in the image has:

• ~22 mm internal diameter
• ~26 mm external diameter
