A Complete Buying Guide to a High-Quality Seed Tray
Seed trays make the process of growing seedlings a whole lot easier. Although it may seem like a simple task to buy a few little seed-starting pots, you will soon discover that there are many different types to choose from. Buying the best-suited seed trays for your seedlings will ensure they grow healthily and quickly. In this guide, we outline everything you need to consider when choosing the best seed trays to start your dream garden.
Advantages of Using Seeds Trays
- Using a variety of containers to start germinating seeds can be messy, labor-intensive, and take up a lot of space. Seed trays hold neat rows of seedlings together, making them quick to plant and easy to move
- Evenly watering or heating the soil of different seed containers can be time-consuming, while compact seed trays make the process of evenly watering and heating the seeds fast and simple
- Drainage holes at the bottom of seed trays with individual cells help to maintain better soil moisture level, as excess water drains out. At the same time, these trays use a base tray to catch excess water and allow the germination of seeds by gradually soaking them from underneath
- Using seed starting trays makes it easy to move whole groups of seedlings at once instead of individually having to move each pot. Whether you need to move your seedlings outdoors or under grow lights indoors, you can easily move 50 or more plants at once
Factors To Consider When Choosing Seed Trays
Seed tray size
Some seed trays with cells can hold up to 70 seedlings while others have only 6 cells. The size you choose will depend on what you are planting, where you are keeping your plants, and how many seedlings you plan to work with. If you have a small greenhouse with plenty of space for your seedlings, a big tray is a good idea. If you want to keep your seedlings on the windowsill in your home, opt for a smaller tray.
Seed tray materials and construction
Seed starting trays are either made of plastic, which is reusable or they are made from a biodegradable material such as peat which is generally not used more than once.
Both types of trays work well to grow seedlings. The tray material you choose may depend on a few different factors.
Plastic trays
If you are an avid gardener and use trays every season, it will be more cost-effective to get reusable trays. The thicker the tray, the more durable it is, however, it is also harder to remove the seedlings from a plastic tray for transplanting.
If you are reusing your trays keep in mind that you will need to clean them and have some storage space to keep them where they won’t get damaged.
Organic veggie gardeners should opt for BPA-free polypropylene plastic seed trays that will not leach chemicals into the planting soil.
Some plastic trays are very thin and intended for one or two uses only. As they are thin, they are easy to manipulate, allowing you to remove the seedlings from the tray without much effort. However, in doing this, you will also likely break them. These types of trays are generally meant to be thrown away after the first or second use, which might not bother you since they are inexpensive. However, plastic waste is not great for the environment.
Biodegradable trays
Biodegradable trays cost more, but they offer many benefits when it comes to the health of your seedlings and the environment. When your seedlings are ready to be transplanted outdoors in your garden, there is no need to remove them from the pots. Simply place the whole pot with the plant in the soil. The pot will break down naturally over time and the roots will spread into the ground. This prevents any transplant shock, stem damage, and root disturbance during the replanting stage. It also makes the entire process less messy and much quicker.
Seed Tray Accessories
Check whether your seed tray purchase includes any of these items. You can choose a kit that includes all the extra items or buy what you need separately.
Dome lid
Some seed trays come with a dome lid. This clear plastic lid allows you to control the temperature and creates a humid environment ideal for seed germination. Domes will either be solid or have adjustable vents to allow humidity control. If you purchase a dome separately, make sure it matches the size of your seedling tray so that it seals around the edges.
Base tray
Base trays are fairly flat with no cell structure and are used to keep cell trays organized. Placing your cell tray in the base tray allows you to catch drainage water from the cells and also allows you to water seedlings from underneath to reduce pest and disease problems. Base trays can also be used for hydroponic growing, wheatgrass, microgreens, and help keep things clean.
Watering mat
Watering mats can be used to draw water to the seed tray cells without oversaturating the soil mix.
Heating mat
Heating mats are usually purchased separately and don’t come with a seed starting kit. They are a great accessory for early indoor growing since they increase germination and growth rates by providing the ideal temperature.
Labels
Don’t forget what you have planted. Labeling your seedlings might be necessary, especially if you are new to gardening and not yet proficient at differentiating all your seedlings by just looking at them.

People Also Asked
A: The length of time will depend on the size of the tray cells. As soon as you see roots growing out of a jiffy pellet or coir pot you need to transplant them. As a rough guide, a 12-cell tray can keep seedlings up to 10 weeks while 72-cell trays will only be big enough for two to three weeks.
A: The best way to remove seedlings is to turn them over in your hand and softly push or tap the bottom of the tray to loosen the soil and roots so it slides out in one piece. Trying to tip over a solid 48-cell tray will most likely damage the seedlings. Never pull the seedling by the stem. If the roots seem stuck to the cell tray, slide a popsicle stick or butter knife gently around the edges to loosen and tip the cell over.
A: This may depend on the type of plant. Generally speaking the optimal temperature for growing seedlings is between 65°F and 75°F.
