Seedling Tray
Seedling trays or seed trays are made up of foldable plastic material. There are cells (holes) throughout the trays. These cells should be filled with a sowing medium like soil, cocopeat, or sand. Depending on the type of plants, 2-3 seeds are sown in each cell. Trays are watered regularly as the seeds germinate.

A seed starting tray is a gardening tool specifically designed to hold multiple seeds, starting from the germination stage, until the seedlings are ready for transplantation. Using such a tray ensures better nutrient availability for each seed and eliminates the need for multiple plantings.

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

There are a few different types of seed trays, including:
• 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). You can find mesh seed trays from Agro Cover-Up.
• Solid seed tray with drainage holes – a solid seed tray with drainage holes allows for adequate drainage but allows the 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. You can find solid seed trays with drainage holes from AK Industry.
• Solid seed tray without drainage holes (leakproof 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). Since it holds water, it can be used to catch the excess water from watering seeds, or it can be used to water from below. You can find solid seed trays without drainage holes from Agro Coverup.

How Many Seeds we can Put in A Seed Tray?
The number of seeds you can put in a seed tray depends on a few things:

• Seed type
The type of seed you plant affects the spacing, and it can vary quite a bit! For example, if planting microgreens, you can plant the seeds very close together (1/8 to ¼ inch apart) in a tray without a cell flat inside. On the other hand, tomato seeds might be 2.5 inches apart to give seedlings enough space to grow without getting their roots tangled together. Pelleted seeds are also larger than ordinary seeds.
• Tray size
The larger the tray, the more seeds you can fit inside. If you go without a cell flat, you can plant seeds closer together, but you run the risk of the roots getting tangled. This increases the chances of transplant shock later on.
• Cell size
Smaller cells in a cell flat mean more cells in a tray. However, smaller cells leave less space for seedlings to grow, so you will need to transplant them sooner.
• Germination rate
If your seeds are old, the germination rate may be low. In that case, you may want to put more than one seed in each cell or put seeds close together in a tray.

Do Seed Trays Need Drainage Holes?
It depends on how you are using the tray. If you are planting seeds directly in the seed tray, without a cell flat, then the seed tray should have drainage holes. Otherwise, the soil will stay too wet, and the seedlings may suffer from damping off.

If you use the seed tray to hold smaller containers (pots) or a cell flat, then you will need a seed tray without drainage holes. That way, it can catch extra water after you water your seeds. You can also use a seed tray without drainage holes to water from below.

How can we Water a Seed Tray?
There are two good ways to water a seed tray:
• Water from below
• Water from above (use a spray bottle!)

Watering A Seed Tray from Below
Here are the steps for watering a seed tray from below:

• First, find a container that is large enough to hold the seed tray.
• Next, put the seed tray inside the container.
• Then, add some water to the container (not to the seed tray!).
• Now, wait until the soil in the seed tray soaks up water from below (through the drainage holes in the tray or the cells).
• If the soil is still too dry, you can add more water to the container.
• Repeat this process until the soil is moist enough, and then get rid of the excess water in the container.
