What it is

Compact plugs of buffered coco coir, each held in a fine mesh that biodegrades in soil. The buffering step washes away excess salts and balances pH, so your seeds get a clean start. When seedlings are ready, plant the whole plug: roots are never disturbed, and the mesh breaks down on its own.

Keep them moist and bright

Plugs dry out faster than pots, so check them daily and keep them evenly moist while your seedlings get going.
