Starting plants from seed offers a range of benefits compared to purchasing nursery-grown plants. These advantages make seed starting an attractive option for many gardeners, from beginners to experienced enthusiasts. Here are some of the key benefits:

  1. Cost-effectiveness: Growing plants from seeds can be significantly more economical than buying nursery plants. Seeds are generally cheaper and can be purchased in larger quantities. This allows you to grow a greater number of plants at a fraction of the cost of purchasing nursery-grown plants.
  2. Variety: When you choose to start plants from seeds, you have access to a vast array of plant varieties that may not be available at your local nursery. This enables you to grow unique and heirloom varieties that can be difficult to find as nursery plants. The wider selection also allows for more creativity and customization in your garden design.
  3. Satisfaction: There is a sense of accomplishment and satisfaction in nurturing plants from seed to maturity. Watching the seeds germinate and grow into healthy, mature plants can be a gratifying and educational experience for both new and experienced gardeners.
  4. Learning opportunity: Growing plants from seeds offers a unique opportunity to learn about the life cycle of plants, as well as the specific needs and characteristics of each variety. This knowledge can be valuable in developing your gardening skills and understanding of plant care.

Thing to Consider When Choosing the Best Seed Starting Trays

When choosing the best seed starting trays for your gardening needs, there are several factors to consider. These factors will help you select the right trays that will enhance the germination process and make it easier for you to manage your seedlings. Here are some key aspects to consider:


Seed starting trays are made from various materials, such as plastic, biodegradable materials like peat or coir, and even metal or ceramic. Plastic trays are the most common, as they are durable and reusable, but biodegradable options are more eco-friendly and can be planted directly into the soil without disturbing the roots. Choose the material that best suits your preferences and gardening practices.

Tray size and amount of cells

Seed starting trays come in various sizes, with different numbers of cells. Consider the number of plants you want to grow and the available space for the trays in your growing area. Larger trays can hold more seeds, but they may be harder to manage and take up more space. Smaller trays may be more convenient for those with limited space or who want to grow fewer plants.

Cell size and depth

The size and depth of the cells in a seed starting tray are essential, as they determine the size of the seedlings that can be grown and how much space their roots will have to develop. Larger cells are suitable for plants with deeper root systems, while smaller cells are ideal for plants with shallow roots. Make sure to choose a tray with cell sizes that match the needs of the seeds you will be planting.


Proper drainage is crucial for healthy seedling growth. Trays should have drainage holes in each cell or at the bottom of the tray to allow excess water to escape and prevent root rot. Some trays come with a separate bottom tray to catch the drained water, which can be helpful in maintaining a clean growing area.

Reusability and durability

If you plan to use your seed starting trays for multiple growing seasons, consider the durability of the trays. Higher-quality materials and construction will ensure that the trays can withstand repeated use without cracking or breaking. This will also save you money in the long run, as you won’t have to replace trays as often.


Seed starting trays can vary significantly in price, so it’s important to consider your budget when making your decision. While more expensive trays may offer better durability and features, more affordable options can still provide satisfactory results for many gardeners.


Humidity Dome

Many seed starting trays come with a clear plastic dome or cover, which helps to retain moisture and maintain a stable temperature for the seeds. This can enhance germination rates and ensure more consistent growth. If this feature is important to you, look for trays that include a humidity dome.

Seedling Heat Mat

Depending on what type of plants you’ll be growing, a seedling heat mat can be invaluable. Warm weather vegetables such as peppers and tomatoes need the soil to be over 75F to germinate properly. NOTE: Always use a temperature control thermostat with a heat mat.

Plant Tags

As you sow your seeds, you’ll need to label the cells. Plant tags can be inexpensive plastic plant tags or nice wooden markers. You could even use a popsicle stick.

Final Thoughts

We always list our favorite product at the top of the page, in this case it’s the Burpee SuperSeed 16XL. We feel that the durability, functionality, and cell size of these seed starting trays is superior and will suite the needs of most gardeners. However, for those on a budget or just starting out, the small trays are the most cost-effective choice and it even includes humidity domes.

I hope this review has been helpful in finding the best seed starting trays for your application. If you are looking for seeds to fill your trays, please feel free to visit our seed store.

FAQ: Seed Starting Trays

Does it save money starting seeds?

Consider this…a packet of seeds that will grow 20 plants may only buy one or two seedlings from a nursery. Of course, there will be an initial investment in equipment. However, buying quality planting tools that will give you years of enjoyment will pay for itself in no time. Check out this link for more ways to save money when starting seeds.

How many seed starting trays do I need?

Once you have figured out how many plants you will have in your garden, there are a few things to consider. Some gardeners choose to grow multiples of each plant in case some seedlings don’t survive. However, this requires more trays. To save space, many gardeners choose to plant more seeds per cell. This reduces the number of seed starting trays needed and ensures at least one of your seeds will sprout. If there are many seeds growing in each cell, you can remove the weakest seedlings later.

Do I need a humidity dome?

A humidity dome will increase your chances of success when growing from seed. Even some of the best seed starter trays don’t come with a humidity dome, but these can be purchased separately for a reasonable price.

Should I use a seedling heat mat?

Cold-weather crops like spinach, lettuce, and other leafy greens don’t need a heat mat as long as the temperature you start planting at is above 60 F. For warm climate plants like tomatoes, peppers, eggplant, etc., keep the soil temperature at 75-80 F for the best germination time and rate. If you can’t reach these temperatures naturally, consider investing in a seedling heat mat and thermostat. NOTE: ALWAYS use a temperature controller (thermostat) with the heating pad. They are not always included with heating mats, but a thermostat that controls the temperature can be purchased separately. Using the heat mat without a thermostat will most likely result in the seed overheating.

Can I reuse seed starting trays?

With the exception of biodegradable trays, most of the best seed starting trays are reusable if caution is taken when removing seedlings. Even the cheapest plastic trays can be used over and over again. However, we recommend Burpee SuperSeed seed starting trays for ease of use and maximum life.
