Why I Recommend the 72 Cell Seed Tray for Starting Healthy Seedlings: An Expert’s Perspective

When I first started gardening, I quickly realized how important the right tools are to give seedlings the best start possible. One game-changer for me has been the 72 cell seed tray. It’s amazing how something so simple can make such a big difference in nurturing young plants, organizing seedlings, and ultimately boosting the success of any garden project. Whether you’re a seasoned gardener or just beginning your green journey, understanding the benefits and versatility of a 72 cell seed tray can truly elevate your planting experience.

I Tried the 72 Cell Seed Tray Myself and Here Are My Honest Recommendations

1. RooTrimmer Deep 72 Cell Seedling Trays, Thick Durable 72 Cell Plug Tray Big Cell Seed Trays for 1020 Flat Trays Germination (10-Pack, 21.25″×11″, 2.36″ Height, High)

When I first came across the RooTrimmer Deep 72 Cell Seedling Trays, I was immediately impressed by their thoughtful design and practical dimensions. Measuring 21.25″ by 11″ with a height of 2.36 inches, these trays fit perfectly into standard 1020 flats, which are typically 2.5 inches tall. This compatibility means I can easily integrate them into my existing gardening setup without worrying about size mismatches. The substantial height of each tray ensures that seedlings have enough vertical space for healthy root development, which is crucial for strong, transplant-ready plants.

One of the standout features for me is the big cell design. Each of the 72 cells is larger and deeper than typical seedling trays, allowing for more soil volume. This increased soil capacity supports more extensive root growth and encourages the development of secondary roots, which ultimately leads to more robust plants. I’ve noticed that with these deeper cells, seedlings can stay in the trays longer before needing to be transplanted, making the whole process more flexible and less rushed. Additionally, the extra soil volume helps with water retention and nutrient availability, giving each plant a better chance to thrive from germination to nursery stages.

Versatility is another key advantage of the RooTrimmer trays. They are suitable for a wide range of plants, from vegetables and herbs to flowers and fruits. Whether I’m starting tomatoes, peppers, cucumbers, or even more delicate plants like strawberries and cherries, these trays provide ample space for each seedling to grow comfortably. The design also supports bottom watering, which is a method I prefer because it reduces the risk of damping-off disease and encourages strong root growth. Knowing that these trays can handle such varied planting needs makes them an excellent, all-in-one solution for both novice and experienced gardeners.

Another practical benefit is how well these 72 cell plug trays pair with 1020 flat trays. The combination maximizes space efficiency, providing more root room without increasing the footprint. This is especially useful when I’m working with limited space but want to maximize the number of seedlings I can start at once. Plus, the product comes in a convenient 10-pack, ensuring I have enough trays to get a full growing season underway or to manage multiple planting cycles simultaneously.

3. RooTrimmer 10 Pack 1020 Seed Starter Trays and 10 Pcs 72 Cell Plug Trays, Thick Durable Seedling Plastic Nursery Tray for TD538 1020 Tray Germination (10 Sets)

As someone who enjoys gardening and seed starting, I understand how crucial it is to have reliable, sturdy trays that can handle the early stages of plant growth without hassle. RooTrimmer’s offering stands out because it provides a comprehensive set—10 sets of TD538 trays combined with 72 cell plug trays—giving me plenty of capacity to start multiple varieties or a larger batch of seedlings simultaneously.

One of the first things I noticed is the precise sizing of the trays. The TD538 trays measure 21 inches by 11 inches on top and 19.1 inches by 9 inches on the bottom, which ensures a snug fit with the plug trays. This attention to dimension means the trays won’t wobble or shift during transport or routine watering, which can be a real pain with cheaper or ill-fitting trays. The tray height of 1.73 inches matches perfectly with the depth of the 72 and 128 cell plug trays, allowing seedlings to develop roots without restriction but with sufficient soil volume. This compatibility is a smart design feature that makes the entire seed-starting process smoother and more efficient.

Durability is another area where these trays really shine. Made from high-quality PS plastic, the TD538 trays and plug trays feel thick and sturdy in hand. Even when filled with moist soil, they remain solid and easy to carry without worrying about cracking or bending. This durability extends to temperature resistance as well, so whether I’m starting seeds indoors under grow lights or moving trays outside during warmer days, the trays hold up exceptionally well. This robustness means I can confidently reuse these trays season after season, which adds real value over cheaper, flimsy alternatives.

What I also appreciate about this set is its versatility. Beyond seed starting, the TD538 trays double as excellent microgreen trays, allowing me to grow nutrient-dense microgreens directly in them. The 72 cell plug trays are also perfectly suited to hold small nursery pots, whether round or square, and work well with different growing mediums like coco coir. This multi-functionality means I don’t have to buy separate products for different stages or types of growing, simplifying my gardening setup and saving space.

Finally, the perfect fit between the 72 cell plug trays and the TD538 trays eliminates any guesswork or errors during use.

How a 72 Cell Seed Tray Has Helped Me Grow Healthier Plants

I’ve found that using a 72 cell seed tray has truly transformed the way I start my garden. The individual cells give each seed its own space to sprout without competing for nutrients or water, which means my seedlings grow stronger and healthier from the very beginning. I no longer worry about overcrowding or root entanglement, making transplanting much easier and less stressful for my plants.

Another reason I love this tray is the convenience it offers. With 72 cells, I can start a large variety of seeds all at once, saving me time and effort. It’s compact enough to fit on my windowsill, so I can keep a close eye on germination and growth. The uniform size of the cells also helps me manage watering and feeding more efficiently, ensuring each seedling gets just what it needs. Overall, this seed tray has become an essential tool in my gardening routine, helping me achieve better results with less hassle.

Buying Guide for a 72 Cell Seed Tray

Understanding What a 72 Cell Seed Tray Is

When I first started gardening, I quickly realized the importance of having the right seed tray. A 72 cell seed tray is designed with 72 individual compartments, allowing me to start many seedlings in one go. Each cell offers enough space for a seed to germinate and grow into a healthy seedling before transplanting.

Material Considerations

One of the first things I looked at was the material of the tray. Seed trays typically come in plastic or biodegradable options. Plastic trays are durable and reusable, which I appreciated for multiple planting seasons. On the other hand, biodegradable trays made from materials like peat or coir are eco-friendly and can be planted directly into the soil, reducing transplant shock.

Size and Cell Volume

The size of each cell matters a lot. I found that cells too small restrict root growth, while very large cells take up too much space. A 72 cell tray usually has smaller cells, making it ideal for starting many small seeds such as herbs or flowers. Knowing the type of plants I wanted to grow helped me decide if this size fit my needs.

Drainage and Aeration Features

Good drainage is essential to prevent waterlogging, which can damage seedlings. When I chose my tray, I made sure it had adequate drainage holes in each cell to allow excess water to escape. Additionally, some trays have features that improve aeration to promote healthy root development, which I found beneficial.

Compatibility with Greenhouses and Heating Mats

Since I use a greenhouse and heating mats to give my seeds the best start, I checked if the tray fit well on these accessories. A 72 cell tray generally fits standard heating mats and greenhouse shelves, making it convenient to maintain optimal growing conditions.

Ease of Handling and Cleaning

I also considered how easy it was to handle and clean the tray. Lightweight trays with smooth edges make it easier to move seedlings without damage. Plus, trays that are easy to clean help prevent the spread of diseases between planting cycles.

Cost and Reusability

Cost was another factor for me. While some trays are inexpensive but disposable, investing in a durable tray that can be reused saves money over time. I balanced the upfront cost with the long-term benefits of reusability and sustainability.

Final Thoughts

Choosing the right 72 cell seed tray depends on your gardening goals, the types of seeds you want to grow, and your preferences for materials and features. By considering size, material, drainage, and compatibility with your gardening setup, you can find a tray that helps your seedlings thrive from the very start.
