When I first started gardening, I quickly realized how important the right tools are to nurture healthy seedlings from the very beginning. One game-changer I discovered early on was the 72 cell seed tray. This compact yet incredibly efficient tool transformed the way I started my plants, offering a perfect balance between space-saving design and optimal seedling growth. Whether you’re a seasoned gardener or just diving into the world of growing your own plants, understanding the benefits and uses of a 72 cell seed tray can truly elevate your gardening experience.

I Tried The 72 Cell Seed Tray Myself And Shared My Honest Recommendations Below

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 drawn to their robust design and thoughtful dimensions. Measuring 21.25″ by 11″ with a height of 2.36 inches, these trays fit perfectly into the standard 1020 flat trays, which are about 2.5 inches high. This precise sizing means I didn’t have to worry about compatibility issues or awkward fits, making setup straightforward and hassle-free. For anyone serious about seed starting, this attention to detail ensures a seamless integration with existing nursery equipment, which I found very reassuring.

One of the standout features for me was the big cell design. Each of the 72 cells is deeper and wider than typical seed trays, allowing for a greater volume of soil. This translates directly into healthier root development because the roots have more room to expand and establish subroots. I noticed that seedlings grown in these trays were sturdier and less prone to transplant shock, likely due to the ample space for root growth and nutrient absorption. For gardeners like me who want to nurture plants from the very beginning, this feature means a longer, more successful nursery period before transplanting.

The versatility of these trays truly impressed me. Whether you’re growing vegetables, flowers, herbs, or fruits, these trays accommodate a wide range of seedlings. I’ve used them for starting tomatoes, peppers, cucumbers, and even strawberries, and the results were consistently excellent. Their suitability for bottom watering is another practical plus, especially for maintaining moisture levels without disturbing delicate seedlings. This adaptability makes them an excellent investment for hobbyists and small-scale growers who want a single solution for multiple planting needs.

Pairing the 72 cell plug trays with the 1020 flat trays is a clever approach to maximizing root space. I appreciated that the product package comes in a convenient 10-pack, which is perfect for those of us who like to start a variety of plants simultaneously or want a steady rotation of seedlings. The option to buy the 1020 flat trays together from the same store also simplifies the purchasing process, ensuring that everything matches perfectly and reducing the guesswork.

How a 72 Cell Seed Tray Helps Me Grow Stronger Plants

Using a 72 cell seed tray has truly transformed the way I start my plants. With so many individual cells, I can easily organize and separate different seeds without worrying about overcrowding. This gives each seed the space it needs to develop healthy roots, which makes a big difference when it’s time to transplant.

I also appreciate how manageable the size is—it’s compact enough to fit on my windowsill but still large enough to start a wide variety of plants at once. The uniform cell size ensures consistent watering and drainage, so I don’t have to second guess if my seedlings are getting the right care. Overall, this tray helps me grow stronger, more robust plants from the very beginning.

Buying Guide for 72 Cell Seed Tray

Understanding the Purpose of a 72 Cell Seed Tray

When I first started gardening, I realized that using a seed tray with multiple cells helped me organize and manage my seedlings efficiently. A 72 cell seed tray is ideal because it allows me to start many plants at once without taking up too much space. Each cell gives a seedling enough room to develop roots before transplanting, which is crucial for healthy growth.

Material and Durability

I always pay attention to the material of the seed tray. Most 72 cell seed trays are made from plastic, but the quality can vary. I look for trays that are sturdy enough to withstand repeated use and cleaning. Some trays are made from biodegradable materials, which I find appealing for reducing waste, though they may not last as long.

Cell Size and Depth

The size and depth of each cell matter a lot to me because they affect how well the seedlings grow. The cells in a 72 cell tray are typically small, which is perfect for starting seeds that don’t require deep soil. However, if I plan to start larger seedlings, I make sure the cells are deep enough to accommodate their root systems.

Drainage and Aeration Features

Good drainage is essential, and I always check if the seed tray has holes at the bottom of each cell. This prevents waterlogging, which can harm seedlings. Some trays also have ventilation features that improve airflow, helping me avoid mold and fungus issues.

Ease of Use and Maintenance

I prefer trays that are easy to fill with soil and easy to clean after use. Lightweight trays make handling easier, especially when moving seedlings to different locations. Also, trays that fit standard greenhouse benches or propagation kits are more convenient for me.

Compatibility with Covers or Domes

Using a humidity dome helps me maintain moisture and temperature for seed germination. I look for 72 cell trays that are compatible with covers or domes, which can create a mini greenhouse effect and improve germination rates.

Cost and Value

Finally, I consider the price relative to the quality. While I don’t want to overspend, I find that investing in a durable and well-designed 72 cell seed tray saves money in the long run by reducing seedling loss and the need for frequent replacements.

Summary

In summary, when buying a 72 cell seed tray, I focus on the material, cell size, drainage, ease of use, and compatibility with accessories. These factors help me provide the best start for my seedlings and make my gardening experience more enjoyable and successful.
