Gardzen 10 Pack Seed Trays, Reusable Plant Grow Trays, No Drain Holes, 15.7″ x 11.6″
This set of 10 durable PET trays stands out for its reusability and environmentally friendly design, making it a strong choice for serious gardeners who want to reduce waste. Unlike the plastic trays, such as the 10 Plant Growing Trays (No Drain Holes), these trays are built to last multiple seasons, though their weight and rigidity may make handling less convenient. The absence of drain holes means you’ll need to be mindful with watering, but this feature also helps prevent spills and keeps your workspace tidy. The large size accommodates a variety of plant types, from microgreens to small seedlings. However, their heaviness could be a drawback for those needing lightweight options. This pick makes the most sense for gardeners prioritizing durability and eco-friendliness, willing to manage careful watering.
Pros:- Recyclable PET material offers eco-friendly benefits
- Stackable design saves storage space
- Large size supports a range of plant types
- No spill-prone drainage holes
Cons:- Heavy and less flexible than thinner plastic trays

Compared with the Gardzen PET trays, these trays are more lightweight and easier to handle, though they may not last as many seasons if frequently exposed to harsh conditions. Their standardized size fits well with many indoor gardening accessories but limits flexibility if you need different dimensions.

This option is best suited for growers who prioritize affordability and ease of handling, especially in hydroponic or microgreen projects.

Mr. Pen Plastic Growing Trays, 5-Pack, Black, 17×10 inches
This 5-pack of plastic trays offers a practical solution for gardeners needing multiple units at a lower cost.

The size of 17×10 inches fits well for small to medium seedlings, but may fall short if you’re growing larger plants or managing extensive projects. Compatibility with heat mats and humidity domes makes it versatile for indoor propagation. However, the plastic may degrade over time with frequent use, and the size limits its application for larger plants. This set makes the most sense for hobbyists or beginner gardeners needing multiple trays without a hefty investment.

The drainage channels are a key feature, promoting healthy root development compared to non-draining options like the Gardzen trays or plastic trays. The clear pots allow for easy monitoring of root health, a significant advantage for meticulous growers. The trays facilitate transportation and watering, but their bulkiness and specific 4-inch size limit flexibility for larger plants or extensive setups.

This set of durable plastic trays stands out for their reusability and leak-proof design, making them a reliable choice for starting seeds, microgreens, herbs, and salad leaves. Compared with the Growing Trays, 1020 Plant Nursery Trays, these are more compact and easier to handle, especially for indoor setups, but lack drainage holes, which requires careful watering to prevent overwatering. Their compact size (14.5 x 9 inches) fits well on windowsills and indoor shelves, offering a flexible solution for small-scale growers. While they excel in reusability and versatility, they may not be suitable for larger plants or extended outdoor use without modifications.

Seed Starter Trays 300 Deep Extra Large Cells (50 Trays of 6 Cells Each)
This set of deep, extra-large cells offers ample space for developing robust root systems, making them excellent for transplant-ready seedlings. Compared with the Growing Trays, 1020 Plant Nursery Trays, these feature larger cells (2.5″ W x 2.25″ L x 3″ D), which promote healthier, larger root balls, but their design leans toward single-use or careful reuse, limiting long-term durability. Their lightweight, flexible plastic makes handling and de-potting straightforward, yet the larger size and depth mean they may not suit tiny seedlings or microgreens. These trays are best suited for growers who want to avoid transplant shock and need bigger root zones, but they are less ideal for those with limited space or seeking trays for continuous seedling cycles. This makes them ideal for serious growers focused on transplant readiness over reusability.
Pros:- Large cell size promotes healthy root growth
- Lightweight and flexible for easy handling
- Ample space for transplant-ready seedlings
Cons:- Primarily designed for single use, limiting long-term reuse
- Too large for tiny seedlings or microgreens
Best for: Serious gardeners and transplanters aiming for strong root systems in larger seedlings
Not ideal for: Beginners or microgreen growers who prefer small, quick-start trays with high reusability
- Number of Trays:50
- Cells per Tray:6
- Cell Dimensions:2.5″ W x 2.25″ L x 3″ D
- Material:Plastic
Bottom line: Best suited for growers prioritizing strong root systems and transplant readiness over micro-scale seed starting.

Its sturdy BPA-free plastic construction and large size (21″×11″) make it a go-to option for serious greenhouse or large indoor setups. Compared with the smaller 10 Seed Starting Plant Growing Trays, these offer a larger footprint and greater durability, but their bulkier design demands more storage space and may be less convenient for smaller grow operations. The absence of drainage holes means growers must be cautious with watering, yet their compatibility with standard 1020 plug trays makes them highly adaptable for commercial or extensive hobby use. This pick is ideal for those needing a durable, multi-purpose tray that can withstand frequent handling and heavy use.
Pros:- Heavy-duty, long-lasting construction
- Large size accommodates multiple seed trays

Compared with the Seed Starter Trays 300 Deep Large Cells, these are more transparent and provide a broader flat surface, but lack drainage holes, which requires careful watering.

How We Picked
I evaluated nursery trays based on several criteria relevant to greenhouse growers: build quality, material durability, size options, ease of handling, and overall value. I looked for trays that could withstand frequent reuse and harsh conditions, prioritizing sturdy plastics and solid construction. Ease of cleaning and the ability to monitor seedlings without disturbing them also played a role. The ranking reflects a balance between affordability and premium quality, with special consideration for trays that meet the specific needs of greenhouse environments, including drainage options and size versatility.Factors to Consider When Choosing Best Nursery Trays For Greenhouse Use
Choosing the right nursery tray for greenhouse use involves understanding several key factors. Beyond just size and price, you should consider the tray’s material, drainage features, and how it fits into your overall cultivation setup. A well-chosen tray can improve seedling health, simplify maintenance, and increase productivity. Keep these considerations in mind to avoid common pitfalls like purchasing trays that are too fragile or incompatible with your watering practices.Material Durability and Reuse
Opt for trays made from high-quality plastics that resist cracking, warping, and staining over time. Reusable trays are more cost-effective in the long run and reduce waste, but they must be sturdy enough to handle frequent cleaning and handling. Cheaper, thinner plastics may seem attractive initially but often require replacement after a season or two, adding to ongoing costs. Consider the environmental impact as well, choosing trays that are recyclable or made from eco-friendly materials when possible.
Size and Cell Configuration
Match the tray size and cell count to your specific greenhouse needs. Larger trays with more cells are ideal for large-scale operations, while smaller trays suit hobbyists or space-limited setups. Deep cells can support larger seedlings, but they may be heavier and harder to handle. Carefully evaluate your available space and workflow to select trays that streamline your planting process rather than complicate it.
Drainage Features
Proper drainage promotes healthy root development by preventing waterlogging, but trays with no drainage are easier to move and clean. If you opt for trays without holes, plan your watering schedule meticulously to avoid overwatering. Conversely, trays with drainage holes require careful setup—such as using saucers—to prevent mess and excess water accumulation. Consider your watering habits and seedling types when choosing between these options.
Visibility and Monitoring
Clear trays allow you to observe seed germination and early growth without disturbing delicate seedlings, which can improve success rates. However, transparent plastics may be more prone to scratches and may discolor over time, reducing visibility. Opaque trays are more durable but require lifting or removing lids for inspection. Think about your monitoring preferences and whether visual access outweighs other durability considerations.
Price and Long-Term Value
While budget trays may seem appealing initially, they often lack durability, leading to higher replacement costs. Investing in high-quality, sturdy trays can pay off by lasting through multiple seasons, saving money and effort. Balance your budget against these factors, especially if you run a large greenhouse or plan frequent plantings. Remember, the cheapest option isn’t always the most economical in the long run if it requires frequent replacement.
Frequently Asked Questions
Should I choose trays with drainage holes for my greenhouse?
Yes, trays with drainage holes promote better root health by preventing excess water from stagnating around seedlings. They help maintain proper moisture levels and reduce the risk of fungal diseases. However, you’ll need to use saucers or trays underneath to catch excess water, which adds an extra step in watering routines. If you prefer simplicity and are cautious with watering, solid-bottom trays may be suitable, but they require more careful management to avoid overwatering.
How important is tray size for my greenhouse seedlings?
Tray size directly impacts your planting efficiency and space management. Larger trays with more cells are better suited for bulk planting or larger seedlings, saving time in transplanting. Smaller trays are easier to handle and ideal for hobbyists or limited spaces. The key is to match tray size to your crop scale and available workspace—overly large trays can become cumbersome, while too-small trays may limit growth space.
Are clear trays better than opaque trays?
Clear trays offer the advantage of visibility, making it easier to monitor germination and seedling health without disturbing the plants. However, they may be more prone to scratches and discoloration over time, which can reduce visibility. Opaque trays are generally more durable and easier to clean but require lifting or removing lids for inspection. Your choice depends on how much you value observation versus tray longevity and durability.
Can I reuse nursery trays for multiple planting seasons?
Absolutely, using durable trays designed for repeated use is both economical and environmentally friendly. Look for trays made from high-quality, thick plastics that resist cracking and staining. Proper cleaning and storage are essential to prolong their lifespan. Cheaper trays may need replacing after just a few seasons, which can add up financially and environmentally over time.
What should I prioritize if I have limited space in my greenhouse?
In limited space, choose trays that are compact yet efficient, such as small, multi-cell trays or stacking options. Consider trays with a shallow depth if root space is less critical, and opt for those that are lightweight for easy handling. Visibility features can also be helpful to monitor seedlings without moving trays around too much. Prioritize versatility and ease of storage to maximize your limited greenhouse area.
Conclusion
For large-scale commercial growers, investing in heavy-duty, large trays with drainage and multiple cells can improve efficiency and plant health, making the Growing Trays 1020 a solid choice. Hobbyists or small-scale gardeners will find the Gardzen 10 Pack Seed Trays or the Clear Seed Starter Trays offer excellent value and ease of use. Beginners should focus on trays that are durable and simple to handle, like the Mr. Pen Plastic Growing Trays. For those prioritizing visibility and monitoring, clear trays provide a significant advantage. Ultimately, your selection should reflect your scale, budget, and specific needs—balancing durability, size, and features for successful greenhouse propagation.
