Grodan AO36/40 - 36 mm Rockwool Propagation Plugs
Locally stocked & tested
Reliable shipping
Flexible returns
A bigger root zone from day one
Grodan AO36/40 propagation plugs are larger-format stone-wool plugs engineered from molten basalt, giving seedlings and cuttings a bigger root zone right from the propagation stage. The result is strong, even rooting for crops that benefit from extra volume early on.
The pH-neutral, open-fibre structure holds an ideal balance of air and water, and the plugs are stocked locally in Windhoek, Namibia for fast delivery. Pair them with the Grodan Growsmart Tray for clean, well-aerated propagation.
Key Features
- pH-Neutral Stone-Wool: Made from sustainable basalt rock for a clean, inert growing medium.
- Ideal Air-to-Water Ratio: The open-fibre structure keeps roots oxygenated while holding moisture.
- Uniform Performance: Consistent density gives even water and nutrient distribution across every plug.
- Seamless Transplanting: Plugs transfer directly into grow blocks or slabs with minimal root disturbance.
- Flexible Quantities: Available as a single sheet or as a bulk carton for larger propagation runs.
