Description
A clean, consistent start for seedlings and cuttings
Grodan Propagation Cubes are professional-grade stonewool (rockwool) cubes that give seeds and cuttings a sterile, even start. Their lightweight structure holds moisture evenly while keeping plenty of air around the developing roots, and their consistent density and stable pH take the guesswork out of propagation across trays, aeroponics and wider hydroponic systems.
Losing cuttings to damping-off and uneven rooting?
Failed cuttings and patchy germination usually come down to a dirty or inconsistent rooting medium. Grodan's sterile stonewool starts free of pests and disease, while uniform density gives even water distribution and strong root development, lifting success rates and cutting waste.
Key Benefits
- Sterile stonewool free of pests and disease at the start
- Even moisture retention with high air porosity for fast rooting
- Consistent density and stable pH across every cube
- Faster germination and stronger establishment
- Versatile across propagation trays, aeroponics and hydro systems
How to Use
- Pre-soak the cubes in pH-adjusted water (around pH 5.5) before use
- Place seeds or cuttings into the pre-formed hole
- Keep evenly moist, not saturated, in a warm, humid propagator
- Transplant once roots show at the base, straight into your system or medium
