Expanding Plugs

Expanding Plugs

These plugs come in both coco coir and peat varieties that are compressed and expand into a small plug once wet. Expanding plugs are ideal for propagating, as you are able to drop in the seed or cutting and place it in a propagator. As neither peat nor coco coir are inert media, this means that the expanding plugs are not either and therefore they hold the properties of coco coir or peat respectively. Expanding plugs are great in NFT systems, drip irrigation systems and pot culture.
