Jiffy Preforma Plugs

Jiffy Preforma Plugs, also know as Jiffy Glue Plugs, are made from a fully bound, extremely uniform substrate, forming 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. The absence of a net around the plug allows the roots to develop optimally after potting on.

Cuttings grown in Preforma plugs produce notably cleaner  than in other propagation substrates. The number of active root nodes formed at the callous is increased substantially, and stimulates fast multiple root development.

These “glue plugs” are manufactured and packed “wet” (they already contain moisture) and may have small colonies of mold inside of them, because they are a great substrate for flora to flourish in. In 99% of these cases, the fungi are saprophytic fungi and not harmful to plants (non-plant pathogenic). The two most well-known types are :  Trichoderma and Peziza.

When the plugs are placed in a normal nursery environment and watered a few times, the natural balance will be “normalized” and the fungi will disappear.

Plug size: Cylindrical, 30 mm x 50mm.
