Starting plants from seeds is a rewarding way to grow a variety of flowers, vegetables, herbs, and other plants. However, it requires careful attention to detail, such as choosing the right tools and creating the ideal environment for the seeds to thrive. One of the best tools for seed starting is the 72 seedling tray, a highly effective and versatile planting solution that offers convenience, efficiency, and space-saving benefits.

In this article, we will explore the advantages of using a 72 seedling tray, how to use it effectively, and why it’s an essential addition to any gardener’s toolkit.

What is a 72 Seedling Tray?

A 72 seedling tray is a type of plant tray designed to hold 72 individual plant seedlings in separate, small cells. Each cell is typically about 1.5 inches by 1.5 inches, providing enough space for seeds to germinate and grow their first set of true leaves before being transplanted into larger containers or directly into the garden. The tray is generally made from durable plastic and often comes with a matching humidity dome to maintain moisture and temperature, which is essential for successful germination.

These trays are often used for starting a large number of plants in a small space, making them particularly popular for gardeners who want to grow many different varieties at once. The 72-cell configuration is especially useful for small and medium-sized seeds, such as tomatoes, peppers, herbs, and flowers, offering each seedling a designated area to grow without the need for individual pots.

Benefits of Using a 72 Seedling Tray

The 72 seedling tray offers several distinct advantages for gardeners. These benefits can improve your chances of successful germination, save you time, and make the overall seed starting process much easier.

1. Space Efficiency

One of the key advantages of the 72 seedling tray is its ability to maximize space. These trays are compact, yet they allow you to grow a large number of plants simultaneously. A 72-cell tray fits easily on windowsills, countertops, or shelves, making it ideal for people with limited space or for those who want to grow a variety of plants indoors.

2. Optimal Environment for Seed Germination

The individual cells of the tray provide an ideal environment for seed germination. Each cell holds a small amount of seed-starting mix, which promotes good drainage and air circulation around the roots. This environment is perfect for seeds to sprout and establish roots before they are transplanted.

Many 72-seedling trays also come with a clear humidity dome, which helps trap heat and moisture. This creates a mini-greenhouse effect, ensuring that the seeds remain warm and hydrated, increasing the chances of successful germination.

3. Ease of Use

Using a 72 seedling tray is simple and user-friendly. Fill each cell with seed-starting mix, plant the seeds, water gently, and cover with the dome (if provided). The clear dome allows you to monitor the growth of the seeds without disturbing them. Because the tray is shallow, it’s easy to access each individual seedling as it grows, making it ideal for both beginner and experienced gardeners.

4. Reduced Transplant Shock

Transplanting seedlings from one environment to another can 72 seedling tray cause stress, leading to transplant shock. However, when seedlings grow in individual cells within a 72-cell tray, they develop strong root systems that are less likely to experience shock when moved. This is because each seedling has enough space to grow its roots and remains protected from overcrowding, allowing the roots to become strong and healthy.

5. Cost-Effective and Sustainable

For gardeners who want to start a large number of plants, buying individual pots or containers for each seedling can become expensive. A 72-seedling tray offers a much more cost-effective solution. The tray can be reused year after year, saving money and reducing waste. Many seedling trays are made of durable, BPA-free plastic that is designed to last, making it a sustainable choice for eco-conscious gardeners.

6. Organized Seedling Care

The 72-cell configuration helps you stay organized, especially if you are starting multiple varieties of plants. Each cell in the tray can hold a different seed type, allowing you to keep your seedlings separate and easily identifiable. Some trays even come with labels or have a grid design, making it even easier to track your seedlings’ progress.

7. Improved Drainage and Root Health

The individual cells in a 72-seedling tray help ensure that each seedling receives proper drainage. When you water your seedlings, excess water can flow out of the bottom of the tray through drainage holes, preventing waterlogging and root rot. This promotes healthy root development and helps keep seedlings strong and well-nourished.

How to Use a 72 Seedling Tray

Using a 72 seedling tray effectively requires just a few simple steps. Follow this guide for the best results:

1. Fill the Tray with Seed-Starting Mix

Start by filling the cells of the tray with a high-quality seed-starting mix. This mix should be lightweight and well-draining, providing the seeds with the right balance of moisture retention and airflow. Avoid using heavy potting soil, as it can become too dense for seedling roots to penetrate.

2. Plant the Seeds

Place one seed in each cell, following the planting depth recommendations on the seed packet. For small seeds, such as lettuce or herbs, you can lightly sprinkle them on top of the soil and press them gently into the surface. Larger seeds may need to be planted deeper into the soil.

3. Water Gently

After planting the seeds, water the tray gently using a watering can with a fine nozzle or a spray bottle. Make sure to moisten the soil evenly, but avoid over-watering, as this can lead to mold or fungal issues.

4. Cover with a Humidity Dome

If your 72-seedling tray comes with a humidity dome, place it over the tray to create a greenhouse effect. This will help maintain humidity levels and temperature, which are crucial for seed germination. Keep the dome on until the seeds have sprouted and the seedlings have begun to grow strong.

5. Provide Adequate Light

Place the tray in a location that receives bright, indirect sunlight. If you are starting seeds indoors during the winter months or in a location with limited sunlight, consider using a grow light to provide the seedlings with adequate light for healthy growth.

6. Monitor Temperature and Humidity

Keep an eye on the temperature and humidity levels inside the dome. Most seeds prefer a temperature range of 65°F to 75°F (18°C to 24°C). If necessary, adjust the vents on the dome to regulate airflow and humidity.

7. Thin Seedlings and Transplant

Once the seedlings have grown large enough, thin them out by removing weaker seedlings to allow the stronger ones to thrive. When the seedlings are large enough to handle, carefully remove them from the cells and transplant them into larger containers or directly into your garden.

Conclusion

A 72 seedling tray is an excellent tool for anyone who wants to grow a large number of plants from seed. It offers space efficiency, a controlled environment for seed germination, and the ability to keep seedlings organized and healthy. Whether you’re a beginner or a seasoned gardener, using a seedling tray with 72 cells can make your seed starting process much easier and more successful.
