Tailor-Made Plant Plugs

The Preforma plant plug system is probably today’s most flexible growing system available.
You, the grower, chooses tray and substrate out of the wide range of Preforma choices available; making the ‘custom tray-custom substrate’ combination a perfect fit for your operation. Manufactured from the highest quality substrates, held together with a unique binding agent, the Preforma plant plug is suitable to work in any highly automated green - house environment, without exception.



Preforma plant plugs are available in almost every existing tray format used in the horticultural industry, making it a ‘Tailor-made plant plug’ system for every propagator. Most trays, no matter what shape or size, can be filled with one of Performa’s wide range of media, from peat substrates to coconut fibre, a mix of both, with or without perlite. Additional seeding dibbles or cutting holes can be provided as required by the customer. As a specialty, Preforma plant plugs can be provided with a transplanting hole to accom - modate a smaller second plant plug, eliminating transplant shock and root damage. The plug basically keeps growing without interruption and will be ready for final transplant faster.



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, main - tains 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
