Starting plants from seeds is an exciting and rewarding experience, whether you’re a hobbyist gardener or a professional grower. One of the most efficient ways to get your seeds started is by using a 72-cell seed tray. These trays are designed to provide the perfect environment for seedlings to thrive, helping you grow a large number of plants in a limited space. In this article, we’ll explore the benefits of using a 72-cell seed tray, how to use them effectively, and the types of plants that thrive in these trays.

What is a 72 Cell Seed Tray?

A 72-cell seed tray is a planting tray divided into 72 small cells or compartments. These individual cells are designed to hold one seed or seedling each, providing a separate space for each plant’s root system. The trays are typically shallow, which makes them ideal for starting seeds that don’t require deep root systems.

These trays are often used by gardeners to start a large number of plants in a small, organized area before transplanting them into larger pots or outdoor gardens. The uniformity of the cells ensures that each seedling receives the same amount of nutrients, water, and light, promoting healthy and uniform growth.

Benefits of Using a 72 Cell Seed Tray

1. Space Efficiency

   One of the primary advantages of using a 72-cell seed tray is the ability to grow a large number of seedlings in a small space. For gardeners with limited space, such as those gardening in apartments or small homes, the 72-cell tray is a great solution. It maximizes space by allowing you to start multiple seeds in a compact area, giving you the ability to grow a variety of plants without taking up too much room.

2. Cost-Effective

   A 72-cell seed tray is an affordable solution for starting plants, especially when compared to individual pots. The ability to start multiple seedlings in one tray saves both money and time. It’s an excellent option for gardeners on a budget or commercial nurseries looking to start a large number of plants for resale. Furthermore, the trays can often be reused for multiple seasons, making them an environmentally friendly option.

3. Uniform Growth

   Since all the seedlings are started in identical cells, they receive the same conditions of light, temperature, and moisture, leading to uniform growth. This ensures that your seedlings will grow at a similar pace, making it easier to manage them and transplant them when they’re 72 cell seed tray. Uniform growth also means your seedlings will be more likely to thrive once transplanted.

4. Improved Drainage and Root Health

   Most 72-cell seed trays come with built-in drainage holes at the bottom of each cell, which helps prevent overwatering and root rot. Proper drainage is essential for healthy seedlings, as it prevents water from accumulating around the roots, which can lead to fungal infections and other problems. The individual cells also prevent the roots from tangling with one another, promoting better root development.

5. Convenient Watering

   Watering a large number of seedlings can be time-consuming and tricky, especially if they are planted in individual pots. With a 72-cell seed tray, watering becomes more efficient. You can water the tray from the bottom by filling the bottom tray with water, allowing the individual cells to absorb the moisture as needed. This method ensures that each seedling gets the proper amount of water without disturbing the seeds or seedlings.

Types of Plants Suitable for 72 Cell Seed Trays

A 72-cell seed tray is versatile and can be used to start a wide range of plants. It’s ideal for growing small plants that need to be transplanted into larger containers or the garden once they are established. Here are some common types of plants that do well in 72-cell trays:

1. Vegetables

   • Tomatoes: Start tomato seeds in the tray for healthy, uniform seedlings. Once they grow large enough, they can be transplanted into larger pots or your garden.
   • Lettuce and Spinach: These leafy greens are perfect for seed trays as they grow quickly and don’t need deep roots initially.
   • Peppers: Peppers, whether sweet or hot, grow well in the 72-cell seed tray. This method helps keep the plants organized and makes it easier to transplant them when they’re ready.

2. Herbs

   • Basil: Basil thrives in small spaces, and a 72-cell tray provides the perfect environment for it to grow.
   • Cilantro and Parsley: These herbs grow best in individual cells, which makes them ideal for starting in a 72-cell tray.
   • Thyme and Oregano: Both of these herbs do well in shallow cells, as they develop quickly and are easy to transplant.

3. Flowers

   • Marigolds: Marigold seeds sprout quickly and don’t need deep root systems, making them perfect for a 72-cell tray.
   • Petunias: Petunias are another flower variety that grows well in seed trays, benefiting from the organized environment.
   • Sunflowers: For indoor seed starting, sunflowers can be grown in these trays until they are ready to be transplanted outdoors.

4. Annuals and Perennials

   • Coleus: This colorful plant does well in a seed tray and can be transplanted into larger containers or gardens as it matures.
   • Geraniums: Geranium seeds are ideal for starting in a seed tray, especially since they benefit from a controlled environment.
   • Ageratum: Ageratum is a popular flower that can be started in a seed tray, ensuring uniform growth and easy transplanting.

How to Use a 72 Cell Seed Tray Effectively

1. Choose the Right Soil

   To ensure successful germination, use a good-quality, well-draining seed starting mix. Avoid using regular garden soil, as it may contain harmful pathogens and may not offer the right conditions for seeds to sprout. A high-quality seed starting mix will retain moisture while allowing excess water to drain, preventing waterlogged soil.

2. Plant Your Seeds

   Fill each cell with the seed starting mix, ensuring that each cell is evenly filled but not packed too tightly. Plant one seed per cell, following the depth recommendations on the seed packet. Most seeds do well when planted at a depth of two to three times the size of the seed. Cover the seed gently with soil.

3. Watering

   Water the tray thoroughly after planting the seeds, but be careful not to overwater. Water the tray from the bottom by filling the bottom tray with water, allowing the individual cells to absorb moisture. Keep the soil consistently moist, but not soggy.

4. Provide Adequate Light

   Once the seeds begin to germinate, provide adequate light for the seedlings. If you’re growing indoors, use grow lights to ensure your seedlings get 12-16 hours of light each day. If growing outdoors, place the tray in a location where it receives adequate sunlight.

5. Thinning and Transplanting

   Once the seedlings have grown large enough, thin them out to prevent overcrowding. Transplant them into larger containers or directly into your garden when they are ready to be moved. Make sure to handle the seedlings gently to avoid damaging the roots.

Conclusion

The 72-cell seed tray is an excellent tool for anyone looking to start a large number of plants efficiently. It offers space efficiency, cost-effectiveness, and ease of use, making it an ideal solution for both hobbyist gardeners and commercial growers.
