Box Plugs

Box Plugs were developed specifically for export, with the capability to be shipped globally at a reduced cost yet still maintaining the highest quality. Plugs can be placed in trays on location by workers, creating jobs and work. The best balance between smart economics and quality.

Flexibility

Wide range of media available, from peat substrates to coconut fibre, a mix of both.

Rooting

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.

Crops to be grown in box-and transfer plugs

  • 20/40 plugs with sticking hole suitable for a wide range of (bedding) plants from cuttings and or seeds.
  • 30/50 plugs with slit for TC and cuttings with small roots.
  • 30/50 plugs with sticking holes for bigger cutting of woody ornamentals and rootstock.

All Preforma plant plugs are made from high quality substrates produced under stringent Jiffy quality control and feature excellent humidity levels, air permeability and stability.
