Jiffy Preforma Plugs 30mmx50mm

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, mainly 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. The number of active root nodes formed at the callous is increased substantially, and stimulates fast multiple root development.
