Jiffy Coco Plug 41 mm 1000 pieces per box.

The Jiffy Coco plug is a compressed product in which a high-quality substrate is compressed in a fine mesh into a conveniently sized plug. The plug is dry and compressed. Adding water will eventually make the plug seven times bigger. This all happens quite quickly so you can start working almost immediately. The plug is held together by a fine mesh. The mesh ensures an optimal exchange between water and air.
