Grodan 150 plug
The Grodan 150 Plugs propagation tray features 150 rockwool cubes on a single sheet, built for growers who propagate in larger batches. Each plug delivers consistent moisture and airflow for uniform rooting across the entire tray. A cost-effective solution when you need high-volume cloning or seed starting capacity. Available now at Plant & Flower.
Grodan 150 Plugs – high-capacity rockwool tray for volume propagation
When you need to root large numbers of cuttings in one go, the Grodan 150 Plugs tray is an efficient choice. With 150 individual rockwool cubes, this tray nearly doubles the capacity of the Grodan 77 Plugs while maintaining the same trusted Grodan quality. Explore our complete cloning and propagation category for all available options.
Built for batch propagation
Whether you are running a seasonal grow or maintaining a continuous supply of young plants, the 150-plug format keeps your workflow efficient. Each plug is pre-formed to the same dimensions, ensuring every cutting receives identical growing conditions from day one.
Inert substrate, full nutrient control
Grodan rockwool contains no organic matter or nutrients. This means you decide exactly what your cuttings receive through your feed solution. For growers who track EC and pH closely, this level of control is essential for achieving repeatable results batch after batch.
Pair with other propagation media
Some growers like to compare substrates side by side. The Rockwool Paperbus 34 offers a smaller plug count in a different format, making it useful for trial runs or smaller projects alongside the Grodan 150.

Is the Grodan 150 tray more cost-effective than the 77-plug version?
Yes, the price per plug is lower with the 150-plug tray compared to the 77-plug version. If you regularly propagate in larger quantities, the Grodan 150 offers better value while delivering the same rockwool quality and rooting performance.
What size propagation tray do I need for the Grodan 150?
The Grodan 150 fits most standard large propagation trays. If your tray is smaller, you can cut the rockwool sheet to size with a sharp knife. Cut between plugs to keep each cube intact and functional.
Do I need to adjust pH when using Grodan rockwool for cloning?
Yes. New rockwool can have a slightly alkaline pH. Pre-soak the tray in water adjusted to pH 5.5 before inserting cuttings. This neutralises the substrate and creates the right environment for root development from the start.
