Super Sprouter® 72 Cell Plug Tray Insert For Square Plugs

Super Sprouter 72-Cell Plug Tray Insert, Square Cells

Start 72 seedlings or cuttings in one standard 10 x 20 propagation flat. This square-cell insert is heavier duty than competing inserts, so it holds its shape through filling, watering, and transplanting day.

Why growers choose this insert

• 72 square cells: a dense layout that keeps plugs upright and evenly spaced in one tray.
• Heavy-duty plastic: sturdier than comparable inserts for reliable reuse and easy handling.
• Standard fit: drops snugly into any standard 10 x 20 propagation tray, no holes required in the insert itself.
• Works with your media: pair with soil, coco, rockwool cubes, or your preferred plug media.
• Part of a full family: Super Sprouter also makes round-hole and tear-away inserts, so you can match the cell shape to your starts.

How to use

Fill the cells with your preferred propagation media, moisten, and sow seeds or insert cuttings. Place the insert in a 10 x 20 tray, cover with a humidity dome, and transplant once roots are established.
