Unlike the 10 Plant Growing Trays with Drain Holes, these lack drainage, which can be a pro or con depending on watering preferences. Their reusable design and sturdy construction make them ideal for growers who want long-term use without worrying about holes clogging or damage. However, the absence of drainage means you’ll need to manage watering carefully or use additional trays for excess moisture.

This pick is best suited for experienced growers or those with specific hydroponic needs who prioritize durability and multi-use functionality.

Mr. Pen Plastic Growing Trays, 5 Pack, 17×10 inches, Black
This set of five 17×10 inch trays offers a lightweight, easy-to-handle solution for seed germination and microgreens. Compared with the larger 10 Plant Growing Trays (No Drain Holes), these are more manageable for small spaces or beginner gardeners. Their raised edges help contain soil and water, simplifying cleanup and plant management. However, the plastic material is less eco-friendly and the size may not suit larger plants or extensive projects. The lack of drainage holes means watering must be controlled carefully, especially for beginners unfamiliar with water management. This set makes sense for hobbyists or indoor growers starting small but might limit larger-scale operations.

Compared to the 10 Plant Growing Trays (No Drain Holes), these facilitate easier watering without risking over-saturation or root rot. Their compatibility with standard grow mats and micro-mats makes them versatile for various indoor gardening setups. The tradeoff is that the drain holes require careful water management; excess water can spill if not monitored.

This 10-pack of 10×20 inch trays offers a large, multipurpose solution for seedling and clone propagation. Compared with the smaller 17×10 inch Mr. Pen Trays, these provide more space for extensive projects, making them ideal for commercial or large hobby setups. Their lack of drain holes means water must be managed carefully, similar to other no-drain options. Their robust design supports healthy root development across various mediums, including hydroponics and soil.

Made from reinforced polypropylene, these trays resist warping and cracking, making them ideal for frequent reuse in both indoor and outdoor environments.

Growing Trays, 1020 Plant Nursery Trays, Heavy Duty Seed Starter Flat, 21″×11″, 10 Pack, 1.6″ Deep, Without Holes
This set from RooTrimmer offers heavy-duty, BPA-free plastic trays designed to securely hold standard 72 or 128 cell plug trays. They are notably robust, making them suitable for commercial or serious hobbyist use, especially where the durability of MIXC trays might be overkill. Their no-hole design prevents leaks, similar to the 10 Seed Starting Plant Growing Trays, but they excel in fitting standard plug trays snugly, which can be a significant advantage for hydroponic systems.

Bottom line: This tray set is perfect for growers who need sturdy, professional-grade containers for seedling and hydroponic starts, but less so for larger plants or those needing drainage.
How We Picked
These products were selected based on their build quality, size, drainage features, and user feedback. I prioritized trays that are versatile, durable, and suited for greenhouse environments, weighing their cost against longevity and usability. The ranking reflects a balance between performance, value, and specific features like drain holes or size, helping buyers identify the best options for different needs. My goal was to highlight products that stand out in either quality or price, ensuring a comprehensive overview for various growers.Factors to Consider When Choosing Best Grow Trays For Greenhouse Benches
Choosing the right grow tray for greenhouse benches involves considering several key factors beyond just size and price. Understanding these factors can help prevent common mistakes, such as selecting trays that don’t drain properly or are too fragile for frequent use. A thoughtful approach ensures your plants grow healthily and your setup remains efficient over time.Drainage and Material
Drainage features are critical for preventing waterlogging and root rot. Trays with drainage holes promote healthy plant growth but may require additional trays or saucers to catch excess water. The material of the tray also impacts durability—thick, high-quality plastics resist cracking and warping, especially in humid environments. Cheaper trays lacking drainage or made from brittle plastic may save money upfront but often need replacement sooner.
Size and Compatibility
Most greenhouse growers prefer standard sizes like 20×10 inches, which fit common benches and shelving. However, larger or smaller trays can be more suitable depending on the plant types or space constraints. Always measure your bench space beforehand to ensure compatibility. Oversized trays might be more cumbersome to handle, while smaller ones could limit planting capacity.
Durability and Reusability
Investing in heavy-duty trays pays off over time, especially if you plan to grow season after season. Look for trays with reinforced edges and thick plastics that withstand frequent cleaning and handling. Reusable trays reduce waste and long-term costs, but they require proper cleaning to prevent disease spread. Cheaper, disposable options may seem attractive initially but tend to deteriorate faster, increasing replacement costs.
Ease of Cleaning and Maintenance
Smooth surfaces and removable parts make cleaning easier, which is vital for preventing pests and diseases. Trays with simple designs are less likely to trap dirt or become difficult to disinfect. Consider whether the trays can be easily sanitized, especially if you grow multiple plant varieties or switch crops frequently. Proper cleaning routines extend tray life and improve plant health.
Pricing and Value
Price varies widely based on size, material, and features. While budget trays may suffice for small hobby growers, commercial growers should consider investing in more durable, feature-rich options. Balancing upfront costs with long-term durability and performance helps ensure value. Sometimes, paying a premium for a sturdy, well-designed tray prevents frequent replacements and maintenance hassles.
Frequently Asked Questions
Do I need drainage holes in my grow trays?
Drainage holes are essential for preventing overwatering and root diseases, especially in humid environments. They allow excess water to escape, promoting healthier root systems. If your setup involves watering from above or frequent irrigation, trays with holes are highly recommended. However, if you prefer to control watering manually or use a drip system, trays without holes can work but require additional saucers or trays to catch runoff.
Can I use regular plastic trays for germinating seeds?
Yes, many growers successfully use standard plastic trays for seed germination, provided they are designed for reuse and are easy to clean. Look for trays with drainage holes to avoid waterlogging, which can rot seedlings. Reusable trays with durable plastic offer better longevity and hygiene, making them suitable for multiple planting cycles. Avoid cheap, brittle trays that may crack under frequent use or cleaning.
What size grow tray should I choose for my greenhouse bench?
The size depends on your space and plant types. Most growers find 20×10 inch trays to be versatile and compatible with standard benches. Larger trays, like 21×11 inches, provide more planting area but can be heavier and harder to handle. Smaller trays are suitable for limited space or specific microgreen crops. Measure your bench to ensure the trays fit comfortably without overcrowding.
Are heavy-duty trays worth the extra cost?
Heavy-duty trays tend to last longer, resist cracking, and withstand frequent cleaning, making them a good investment for serious or commercial growers. While they cost more upfront, their durability often offsets replacement expenses. For hobbyists or occasional growers, standard plastic trays may suffice but keep in mind they might need replacing sooner, especially if mishandled or exposed to harsh conditions.
What features should I prioritize for a beginner?
Beginners should look for trays that are durable, easy to clean, and come with drainage if needed. Simpler designs without complex features reduce the risk of mistakes—such as overwatering or difficulty in handling. Budget-friendly options that are sturdy and re-usable offer a good starting point, allowing new growers to focus on learning without worrying about frequent replacements or complicated maintenance.
Conclusion
For those seeking the best overall performance, the 10 Plant Growing Trays with Drain Holes strike a balance between durability and functionality, making them suitable for most growers. Budget-conscious hobbyists will find the Mr. Pen Plastic Growing Trays to be a dependable, affordable choice. Growers with larger operations or professional setups should consider investing in the Growing Trays, 1020 Plant Nursery Trays for their heavy-duty construction and extra longevity. Beginners will benefit from simple, easy-to-clean options, while those with specific needs, like microgreens or hydroponics, should pay attention to tray size and drainage. Ultimately, selecting the right tray depends on your growing scale, budget, and setup preferences.
