Preforma Plant Plugs are manufactured from the highest quality substrates and held together with a unique binding agent. Preforma achieves unrivalled rooting speeds and take rates for nursery stock crops.


The unique manufacturing process produces an extremely uniform substrate and a structure with hundreds of micro air pockets evenly distributed throughout the plug. This stimulates superior fibrous root growth throughout the full depth and volume of the plug. As the substrate is fully bound, there is no compaction with transport or irrigation. This superior substrate structure holds water well, maintains excellent drainage properties, conserves water, and reducing losses particularly in overwintered crops. The absence of a net around the plug allows the roots to develop optimally after potting on. Cuttings grown in Preforma produce notably cleaner callous than in other propagation substrates, and far less rot. The number of active root nodes formed at the callous is increased substantially, and stimulates fast multiple root development.

Faster Sticking & Potting

Plants in Preforma plugs produce fibrous roots within the plug rather than extended tap root systems outside the plug. Preforma products, compared to the competitors, make potting quicker and greatly reduce the risk of root damage and disease. Because the Preforma Plant Plug is supplied ready to use, sticking speeds are up to 20% faster than in other discrete plugs. With Preforma there is no labor needed to fill or water trays filled with loose substrates.Trials with leading nurseries have also proven potting speeds to be significantly quicker than other discrete or loose fill plugs, due to the Preforma Plug’s unique ability to easily pull from the tray.
