⚠️ Two-Part System: This is the outer ring only. You also need a net insert (sold separately) for the system to work.

This flower-shaped sprouter ring sits on the rim of mason jars, cups, or glasses to hold your sprouter net in place. The net insert twists and locks into this outer ring, suspending seeds or cuttings over water for regrowing.

How It Works:

  • The outer ring sits on your jar or cup rim
  • The net insert (sold separately) twists and locks into the ring
  • Seeds or scraps sit in the net, suspended over water
  • Both pieces required for the complete sprouting system

3D-printed in eco-friendly PLA. Available in multiple colours.

Overview

Grow new plants from kitchen scraps and seeds using jars you already own. The PureLayer Mason Jar Sprouter Ring is a clean, reusable outer attachment designed to replace toothpicks and disposable regrow methods, providing a stable base for sprouting and regrowing in water.

Designed to sit securely on jars and glasses, the ring supports interchangeable sprouter nets (sold separately), allowing roots to grow freely while keeping seeds or cuttings stable and upright.

Key Benefits

  • Provides a reusable alternative to disposable regrow methods.
  • Creates a stable platform for water-based regrowing.
  • Compatible with interchangeable PureLayer sprouter nets (sold separately).
  • Fits jars and glasses commonly found in the home.

How It Works

The sprouter ring sits on top of a jar or glass filled with water. A compatible sprouter net (sold separately) rests within the ring, holding seeds or cuttings above the waterline while roots grow downward into the water below.

The modular system allows nets to be swapped depending on the type and size of the seed or cutting being regrown.

Where It's Best Used

Ideal for windowsills, kitchen counters, and indoor growing spaces.
Suitable for homes, apartments, and low-space environments where simple water-based regrowing is preferred.
