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 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.
Plug size: Cylindrical, 30 mm x 50mm.
Our 84 cell seedling tray works well with these Jiffy Preforma Plugs, but you can also also other trays with holes similar to the plug dimensions.
