Net Types

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

These modular sprouter nets twist and lock into the outer ring attachment to suspend seeds, cuttings, or scraps over water for regrowing. Choose from multiple insert designs for different plants like avocado, mango, spring onions, and more.

How It Works:

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

3D-printed in durable, long-lasting PETG designed for years of reuse. Various insert designs to suit different plant types.

Overview

(General, not variant-specific)

Grow new plants from kitchen scraps and seeds using jars you already own. The PureLayer Mason Jar Sprouter Lid is a clean, reusable regrow system designed to replace toothpicks and disposable methods, holding seeds securely while allowing roots to grow freely in water.

The modular design supports interchangeable inserts, making it easy to regrow a wide range of seeds, bulbs, and cuttings using simple water-based setups.

Key Benefits

Provides a clean and reusable alternative to disposable regrow methods.
Holds seeds and cuttings securely while allowing natural root development.
Modular system with interchangeable inserts for different regrow types.
Compatible with jars and glasses commonly found in the home.

How It Works

The sprouter lid sits on top of a jar or glass filled with water, holding seeds or cuttings in place above the waterline while roots grow downward into the water.

Interchangeable inserts cradle different seed shapes and stem sizes, allowing stable regrowth without soil or complex setups.

Where It's Best Used

Ideal for windowsills, kitchen counters, and small indoor growing spaces.

• Avocado insert: Suitable for large pits and rounded seeds such as avocado and similar-sized bulbs.
• Mango insert: Suitable for flat or elongated seeds such as mango and stone fruit seeds.
• Jackfruit insert (3-seed): Suitable for regrowing multiple medium-sized seeds such as jackfruit or large bean-type seeds.
• Spring onion insert (7-stem): Suitable for spring onions, green onions, leeks, chives, and similar regrowing stems.
• Celery insert: Suitable for celery bases, lettuce bases, and pineapple heads.
