Who This Is For
- You are switching to round stonewool because your current media has high resistance that slows down early rooting.
- You are scaling up propagation because your manual tray filling creates too much variation in moisture levels.
What We Found
- These plugs keep their shape even when soaked, which is a massive help when you are moving them into larger blocks.
- The fibre structure in these allows for faster dry-backs compared to cheaper, generic rockwool alternatives.
What Users Say
- Facilities using these say they stopped seeing root rot in the propagation stage due to the better drainage.
- Growers who switched from peat find that transplanting is much cleaner since the plugs never crumble or fall apart.

FAQs
What are Cultiwool Round Macro Plugs best used for?
They are ideal for starting seeds and rooting cuttings for hydroponic or soil-based cultivation. Their design promotes rapid, healthy root development in the early stages of a plant's life.
How do these plugs differ from other rockwool cubes?
These plugs feature an advanced fiber structure with a superior air-to-water ratio. This holds water longer while offering less resistance to root growth, leading to faster establishment compared to standard media. They are also a great alternative to the popular Cultiwool 1.5" cubes for growers who prefer a round shape.
Do I need to pre-soak the plugs before use?
Yes, it is highly recommended to pre-soak the stonewool plugs in pH-adjusted water (typically pH 5.5-6.5) for about 15-30 minutes before inserting your seeds or cuttings. This stabilizes the material and creates an ideal environment for germination.
What trays are compatible with these plugs?
They are designed for maximum flexibility. For an optimal fit, use a 50-cell round propagation tray, where they sit slightly below the surface for easy handling. They also fit snugly in standard 50-cell square trays.
When should I transplant my plants from these plugs?
Transplant once you see a healthy root system emerging from the sides and bottom of the plug. They are designed for seamless integration into larger growing media, such as Cultiwool growing blocks or slabs.
Are these plugs suitable for large-scale commercial operations?
Absolutely. They are manufactured in the Netherlands by a brand preferred by industrial propagators. Sold by the case of 1980, they are designed for the consistency and reliability required in commercial cultivation.
