What Is A Seed Tray?

A seed tray is a container that is used to plant multiple seeds at once.  A seed tray is sometimes called a seed starting tray.

Parts Of A Seed Tray

There are two basic parts to a seed tray, one of which is optional:

• Tray – this is the outer part that holds soil, individual containers (pots), or a cell flat.  When used with a cell flat, the tray is used for watering from below.
• Cell flat (plug flat) – this is the optional inner part.  You can put a cell flat inside of a tray to separate seeds from one another

 Different types of seed trays

Mesh seed tray

A mesh seed tray allows water to drain out easily.  A mesh seed tray is best for holding multiple individual containers (pots).  A drawback is that the holes in a mesh seed tray are too large to hold soil without it falling through or washing away when watered.

Solid seed tray with drainage holes

A solid seed tray with drainage holes allows for adequate drainage, but allows soil to stay moist enough for seed germination.  A solid seed tray with drainage holes is best for planting multiple seeds together in one place.  A drawback is that the seedlings do not have individual cells, so their roots can get tangled together as they grow.

Solid seed tray without drainage holes (leak proof seed tray)

A solid seed tray without drainage holes does not allow for any drainage.  A solid seed tray without drainage holes is best for holding a cell flat (also called a plug flat).
