More Details on Our Top Picks
10 Pack Plant Growing Trays (No Drain Holes) – 20″ x 10″ Seed Starter Grow Trays for Seedlings, Microgreens, Wheatgrass & Hydroponics
This set of 10 durable plastic trays stands out for its suitability in hydroponic systems and microgreen cultivation, offering a reusable option that fits standard 20″ x 10″ hydroponic pads. Unlike the Burpee SuperSeed tray, which uses flexible silicone cells ideal for gentle transplanting, these trays lack drain holes, making them less suitable for soil-based seed starting where excess water needs to escape. Their plastic construction ensures longevity but can pose a risk of cracking over time with heavy use. This pick makes the most sense for growers who prioritize hydroponic setups or microgreens, and don’t need drainage for soil-based seedlings. However, overwatering could lead to waterlogging without drainage holes, and heavy handling might eventually damage the plastic.
Pros:- No drain holes ideal for hydroponic and drip tray use
- Durable, reusable plastic for multiple cycles
- Perfect fit for 20″ x 10″ hydroponic pads and mats
Cons:- Lack of drainage can cause waterlogging in soil-based setups
- Plastic may crack or warp over time with heavy use
Best for: Hydroponic growers and microgreen cultivators seeking reusable, large-format trays
Not ideal for: Gardeners starting soil-based seedlings who need drainage to prevent waterlogging
- Quantity:10 trays
- Material:Durable plastic
- Top Dimensions:21″ x 11″
- Bottom Dimensions:20″ x 10″
- Drain Holes:None
- Compatibility:Fits 20″ x 10″ Sure to Grow Hydroponic Grow Pads
Our verdict“This set is best for hydroponic and microgreen growers who need large, reusable trays without drainage holes.”
Mr. Pen Seed Starter Tray Kits, 6.6″x4.6″, 10 Pack, 120 Cells
This kit offers a compact solution with 10 trays, each containing 12 cells, making it a practical choice for those new to seed starting or with limited space. The included transparent dome with adjustable vents helps prevent overwatering while maintaining optimal humidity, a feature not present in the 10 Pack Plant Growing Trays. Compared to larger trays, these are easier to handle and ideal for small-scale projects. However, their plastic trays may warp over time, especially under frequent use, and the smaller size limits the number of seedlings for larger gardens. This set is best suited for hobbyists or indoor growers focused on starting a handful of plants efficiently.
Pros:- Includes a humidity dome with adjustable vents
- Compact size for small spaces and indoor use
- Transparent trays facilitate seedling monitoring
Cons:- Plastic trays may warp over time
- Limited capacity for larger planting projects
Best for: Beginners or gardeners with limited space wanting a simple, manageable seed starting kit
Not ideal for: Experienced growers with large planting needs who require bigger trays or more capacity
- Size:6.6″ x 4.6″
- Number of Trays:10
- Cells per Tray:12
- Total Cells:120
- Includes:Shovel, Scoop
- Material:Plastic
Our verdict“Ideal for novice gardeners and indoor growers starting small batches of seedlings with ease.”
MIXC 5 Pack 200-Cell Seed Starter Tray with Humidity Dome Propagator Grow Kit
Compared with smaller kits, the MIXC 5 Pack delivers an impressive 200 cells, making it well-suited for growers aiming to start many seedlings indoors or in limited space. The adjustable vents on the humidity domes provide precise control over environmental conditions, a feature absent in simpler trays like the Mr. Pen Seed Starter Kit. The transparent plastic allows easy observation, but the plastic’s durability might be less than heavier-duty options. The stackable design conserves space, making it ideal for those with limited room. Still, the small size of each cell suits only small seeds, which could be restrictive for larger plantings or bigger seeds.
Pros:- Adjustable vents for precise humidity control
- Stackable trays save space
- Transparent plastic for easy seedling monitoring
Cons:- Cells sized mainly for small seeds
- Plastic may be less durable over time
Best for: Indoor gardeners and small-scale producers seeking high volume seed starting in compact space
Not ideal for: Gardeners with larger seeds or those needing bigger individual cells for transplanting
- Quantity:5 sets
- Total Cells:200
- Cell Size:1.5″ x 1.5″ x 2″
- Dome Height:2.75″
- Includes:Garden tools, plant labels
- Material:Plastic
Our verdict“This kit is perfect for space-conscious growers who need a high number of seedlings started indoors efficiently.”
The Hydroponic City Seed Starter Trays, 216-Cell (36 Trays – 6 Cells Each) with Plant Stakes
This set of 36 trays with 6 cells each provides a high-capacity option for serious growers focused on root health and organizational efficiency. The multiple small trays are ideal for seedlings like herbs, vegetables, and flowers, with drainage slits that facilitate proper water management. While the Burpee SuperSeed tray offers larger individual cells, these smaller cells are better suited for quick germination and transplanting, especially in multi-seed setups. The inclusion of plant stakes helps with labeling, but the set does not specify the overall durability or compatibility with larger seedlings. This product benefits those with extensive seeding projects and a preference for modular, reusable trays.
Pros:- High total capacity with 216 cells
- Promotes healthy root development
- Includes plant stakes for organization
Cons:- Requires more space and handling due to multiple trays
- No specific price info; may be overkill for small projects
Best for: Large-scale gardeners and professionals managing many seedlings simultaneously
Not ideal for: Small hobbyists or those starting only a few plants, as the quantity may be excessive
- Number of trays:36
- Cells per tray:6
- Total cells:216
- Cell dimensions:1.5″ x 2.25″
- Includes:Plant stakes
Our verdict“This set suits experienced or commercial growers seeking high-volume, organized seed starting with excellent root development.”
Burpee SuperSeed 36-Cell Reusable Seed Starting Tray for Indoor Seedlings
The Burpee SuperSeed tray uses flexible silicone cells that make transplanting a breeze, minimizing root damage—a clear advantage over rigid plastic trays like the Mr. Pen Kit. Its deep channels and molded corner slots improve drainage and aeration, making it suitable for indoor settings. The silicone cells gently flex to release seedlings, which benefits delicate roots during transplanting. However, the limited 36-cell capacity might not meet the needs of larger gardens or those starting many seeds. The tray is also sold separately from seed-starting mix and grow lights, which adds to the overall cost for a complete setup. This product is ideal for small-scale indoor growers prioritizing healthy root development and easy seedling removal.
Pros:- Flexible silicone cells for easy transplanting
- Deep channels improve drainage and aeration
- Dishwasher safe and reusable
Cons:- Limited to 36 cells, not ideal for extensive planting
- Requires separate purchase of seed starting media and lights
Best for: Indoor gardeners who want gentle seedling removal and minimal root stress
Not ideal for: Large-scale growers or outdoor seed starters needing bigger trays or higher capacity
- Cells:36
- Tray Dimensions:11.5″ x 10-3/8″ x 2-1/4″
- Cell Material:Food-grade silicone
- Rows:Labeled alphanumerically
- Care:Dishwasher safe
Our verdict“This tray is perfect for indoor growers seeking gentle handling and healthy root development for small batches of seedlings.”
120 Cells Seed Starter Tray, 10 Pack Plant Starter Kit
This 10-pack of biodegradable wood pulp seed starter trays stands out for its eco-friendly approach, allowing roots to grow through and decompose into the soil, which can ease transplant shock. Compared with plastic trays like the Epic Gardening 6-Cell Set, these trays are gentler on seedlings but may dry out faster and aren’t as durable under heavy watering. The kit’s inclusion of labels, tools, and a sprayer adds value for organized planting, especially for beginners or those starting multiple plant varieties. The biodegradable material means they won’t last forever, but that’s a tradeoff for reduced environmental impact. These trays are best suited for gardeners prioritizing sustainability and gentle seedling care, especially for indoor or small-scale outdoor use. They may not be the best choice for those needing long-lasting trays or for very heavy watering scenarios.
Pros:- Biodegradable wood pulp trays reduce transplant shock
- Includes labels, tools, and a sprayer for convenience
- Versatile cell size suitable for a wide range of seeds
- Can be cut into individual segments for customized planting
Cons:- Peat-like material may dry out faster than plastic trays
- Biodegradable trays may not withstand heavy watering or prolonged use
Best for: Gardeners seeking an eco-friendly, all-in-one seed starting solution, suitable for indoor use or small-scale outdoor projects
Not ideal for: Those with large-scale planting needs or heavy watering routines that could cause rapid deterioration of biodegradable trays
- Brand:Doubleggs
- Tray Count:10 trays (120 cells total)
- Cell Dimensions:1.6 x 1.6 x 2 inches
- Material:Wood pulp (biodegradable)
- Labels Included:100
- Tools Included:2 mini transplanting tools
Our verdict“This set is ideal for eco-conscious gardeners who want a gentle, all-in-one seed starting kit, particularly for small-scale or indoor gardening.”
Epic Gardening Reusable 6-Cell Seed Starter Trays, 6-Pack (Black)
This set of six durable, reusable trays made from recycled, UV-resistant, BPA-free plastic excels for gardeners who want a long-lasting, low-maintenance option. Compared to the Gardzen 5 Pack 40-Cell Kit, these trays offer fewer but larger cells, which are better suited for seedlings that need more room to develop strong roots. The inclusion of air pruning slots and an open base helps prevent root circling, promoting healthier growth. Large finger holes allow for damage-free transplanting, making them ideal for those who frequently move seedlings. However, their plastic build limits their eco-friendliness and they’re best suited for small to medium-scale projects. These trays suit experienced gardeners or hobbyists who prefer a sustainable, reusable option that can be used season after season, but they may not be ideal for those seeking disposable or biodegradable trays.
Pros:- Durable, reusable construction from recycled plastic
- Air pruning slots and open base promote healthy roots
- Large finger holes enable damage-free transplanting
- Fits standard nursery trays for flexible seedling management
Cons:- Limited to small seed types due to compact cells
- Plastic may degrade over many seasons despite UV treatment
Best for: Experienced gardeners or hobbyists looking for durable, reusable trays that promote healthy root growth and can be used repeatedly
Not ideal for: Beginners or gardeners with large-scale planting needs who require more cell capacity or biodegradable options
- Material:Recycled UV-resistant plastic
- Color:Black
- Cell dimensions:1 9/16″ L x 1 9/16″ W x 2 1/4″ H
- Cells per tray:6
- Number of trays:6
- Special features:Air pruning slots, open base, finger holes
Our verdict“This pick is perfect for gardeners seeking a sustainable, long-term seed starting solution with healthy root development benefits.”
Epic Reusable Seed Starter Tray – 4-Cell, 4-inch, BPA-Free, UV-Treated, Recycled Plastic
This 4-cell, 4-inch tray from Epic offers a compact, durable solution tailored for small-scale seed starters or cuttings. Compared with larger trays like the Gardzen 5-Pack 40-Cell Kits, this tray’s larger cells provide more space for root development, making it better for seedlings needing extra room. Its BPA-free, recycled plastic construction ensures safety and eco-friendliness, though the limited number of cells means it’s less suited for larger projects. The air pruning slots and large finger holes facilitate healthy root growth and easy transplanting, respectively. This tray makes the most sense for gardeners with limited space or those who want to start just a few plants at a time, but it’s not the best choice for large batches or extensive propagation efforts.
Pros:- Durable, eco-friendly recycled plastic construction
- Large cells support healthy root growth
- Easy seed removal with finger holes
- Reusable and BPA-free for safety
Cons:- Limited to just 4 cells, requiring multiple trays for larger projects
- Plastic may wear over time with frequent use
Best for: Small-scale gardeners or hobbyists who want a compact, reusable tray for a few seedlings or cuttings
Not ideal for: Gardeners starting large plant batches or those needing many small trays simultaneously
- Cell size:2 3/8″ x 2 3/8″ x 4″
- Material:Recycled plastic
- Number of trays:4
- Cell count per tray:4
Our verdict“This tray is ideal for small, space-constrained projects where quality and reusability matter most.”
Gardzen 5 Pack 40 Cell BPA Free Seed Starter Tray Kit
This Gardzen kit offers five sturdy BPA-free trays, each with 40 cells, equipped with adjustable ventilation and transparent walls that facilitate easy root monitoring. Compared to the Gardzen 5-Set with humidity domes, these trays don’t include domes but are more straightforward for gardeners who prefer open-air seed starting. The adjustable vents help regulate humidity and temperature, which can be especially helpful for beginners or those starting sensitive seeds. The transparent design is a bonus for observing root development without disturbing seedlings. However, the plastic material may not be as durable as rigid, UV-treated trays, and the lack of domes means extra attention is needed to prevent drying out. These trays suit gardeners who want control over moisture and visibility but aren’t seeking a fully enclosed environment.
Pros:- Adjustable ventilation vents for optimal seed growth
- Transparent cells for easy root monitoring
- BPA-free, non-toxic construction
- Includes sowing tools and plant tags
Cons:- Plastic may require careful handling to avoid damage
- Lacks included humidity domes for moisture control
Best for: Gardeners who want to monitor seedling roots closely and control ventilation, ideal for beginners or delicate seed varieties
Not ideal for: Those starting many seedlings at once or gardeners who prefer enclosed, humidity-controlled environments
- Number of trays:5
- Cells per tray:40
- Material:BPA free plastic
- Includes:Tools, plant tags
Our verdict“This set is well-suited for gardeners wanting visibility and ventilation control, especially beginners monitoring delicate seeds.”
Gardzen 5-Set Seed Starter Tray Kits with Humidity Vented Domes and Bases
This comprehensive Gardzen kit provides five trays with 40 cells each, complete with humidity domes that enable precise moisture control. Compared to the simpler 5-40 Cell Kit, these domes help maintain consistent humidity levels, making them ideal for propagating cuttings or starting seeds that require stable moisture. The adjustable vents allow fine-tuning, while clear domes make it easy to monitor growth without lifting them. Drain holes prevent overwatering, reducing root rot risk. The plastic construction offers durability but may not match the longevity of rigid, UV-treated trays for outdoor use. This set makes the most sense for those starting seeds that need a humid environment or propagating cuttings, but it might be overkill for straightforward seed starting without humidity needs.
Pros:- Adjustable ventilation on humidity domes for moisture control
- Transparent domes for easy growth monitoring
- Drain holes prevent overwatering
- Includes tray, base, and dome for convenience
Cons:- Plastic durability may vary over seasons
- Requires stickers for a tight fit between dome and tray
Best for: Gardening enthusiasts focused on propagating cuttings or maintaining precise humidity for sensitive seeds
Not ideal for: Gardeners seeking a simple, low-cost tray for basic seed starting or those with outdoor, long-term needs
- Brand:Gardzen
- Model Number:GST01-5
- Set Size:5 trays
- Cells Per Tray:40
- Total Cells:200
- Material:Premium plastic
Our verdict“This set excels for gardeners needing controlled humidity environments, especially for propagating cuttings or sensitive seedlings.”
MIXC 10 Pack Seed Starter Tray with Humidity Dome
This seed starter kit stands out for its comprehensive approach, offering 10 reusable plastic trays with adjustable vents, drainage holes, and included humidity domes, making it a versatile choice for those who want a mini greenhouse setup. Compared with the Epic Gardening Reusable 6-Cell Trays, which are simpler and smaller, the MIXC kit provides more space and control, though its plastic construction may not be as durable over multiple seasons. The adjustable vents are a key advantage, giving precise humidity control that benefits beginners and casual gardeners. However, the plastic material might wear faster than sturdier options, and the size could be limiting for larger seed varieties or transplanting later. This kit makes the most sense for hobbyists who want a complete, budget-friendly starter set that covers all the basics without extra purchases.
Pros:- Complete kit with trays, domes, labels, and bases for easy setup
- Adjustable vents provide excellent humidity and temperature control
- Reusable trays promote sustainability and multiple seasons of use
- Compact size fits well on windowsills or small grow spaces
Cons:- Plastic material may degrade faster than more durable options
- Limited to seed starting, not suitable for larger plants or transplanting
- Size may be too small for larger seed varieties or root systems
Best for: Gardeners seeking an all-in-one, affordable seed starting package suitable for small to medium seed varieties
Not ideal for: Experienced growers or those planting larger seedlings who need more durable, larger trays or long-term solutions
- Number of trays:10
- Includes:humidity domes, plant labels, watertight base trays
- Material:plastic
- Features:adjustable vents, drainage holes, reusable
- Size:compact, suitable for small seed varieties
- Durability:moderate, plastic may wear over time
Our verdict“This pick is ideal for beginners or hobbyists looking for an affordable, all-in-one seed starting solution with good control features.”
How We Picked
I evaluated each seed starting tray based on several key factors: build quality, capacity, ease of use, reusability, and value. Durability was prioritized because trays that last multiple seasons save money over time, while capacity determines suitability for different garden sizes. Ease of handling, such as integrated drainage or venting, was also considered, as it impacts germination success and maintenance. The ranking reflects a balanced view of these features against price, ensuring selections are practical for various gardener needs and budgets.Factors to Consider When Choosing Best Garden Seed Starting Trays
Choosing the right seed starting tray involves considering several important factors beyond just capacity or price. Durability and material quality affect how many seasons a tray can be reused, reducing ongoing costs. Features like humidity domes and venting can improve germination rates, especially in cooler or less controlled environments. Size and capacity should align with your planting goals—small trays suit hobbyists, while larger setups benefit serious growers. Lastly, think about ease of cleaning and maintenance, as these influence long-term usability and hygiene.Capacity and Size
Seed trays come in a range of sizes, from small 4-cell units to large multi-hundred-cell setups. Larger trays reduce the need for frequent replanting and are better suited to serious gardeners or those with larger space, while smaller trays are ideal for beginners or limited areas. Think about how many seedlings you want to start at once and whether you plan to transplant or grow directly in the tray. Keep in mind that larger trays may be heavier and more cumbersome to handle, so balance capacity with your physical space and storage options.
Material and Durability
Most seed trays are made from plastic, but the quality varies. BPA-free, UV-treated plastics last longer and are safer for edible plants. Reusable trays tend to be more environmentally friendly and economical over time, but they require proper cleaning to prevent disease buildup. Cheaper options may crack or warp with repeated use, so investing in sturdy materials pays off in the long run. Consider how often you’ll reuse the trays and choose materials that withstand your climate and handling frequency.
Features for Germination
Features like humidity domes, venting, and drainage holes directly influence germination success. Humidity domes create a mini-greenhouse effect, maintaining moisture and warmth—ideal for seeds that need consistent humidity. Venting allows you to regulate airflow, preventing mold and damping off. Proper drainage prevents waterlogging, which can cause seed rot. Evaluate whether these features match your starting environment and seed types, especially if you’re starting many trays simultaneously or in less controlled conditions.
Ease of Use and Maintenance
Ease of handling includes considerations such as lightweight design, snap-on lids, and straightforward cleaning. Reusable trays should be simple to sanitize, which is vital for preventing disease spread between plantings. Trays with integrated handles or stackability can save space and reduce strain during setup and cleanup. Keep in mind that some trays require specific cleaning routines or materials to maintain their integrity over multiple seasons, so factor in the time and effort you’re willing to dedicate to maintenance.
Price and Value
While budget options can perform well for small-scale use, investing a bit more in higher-quality trays often yields better durability and features. Consider how many trays you’ll need and whether buying in packs offers better value. Reusable trays, though sometimes more expensive upfront, tend to be more economical over multiple seasons. Avoid choosing solely on price; instead, weigh the long-term savings and benefits of features like material safety and durability, ensuring your investment supports healthy seedlings season after season.
Frequently Asked Questions
Are plastic seed trays safe for growing edible plants?
Most plastic seed trays made from BPA-free, food-grade, and UV-treated plastics are safe for growing edible plants. These materials do not leach harmful chemicals, especially when used as intended. It’s important to verify the product specifications and avoid trays with recycled plastics that may contain unknown additives. Proper cleaning before use also reduces any risk of contamination, making plastic trays a reliable choice for food crops.
How often should I replace my seed trays?
The lifespan of seed trays depends on the material quality and usage conditions. Reusable trays made from durable plastics can last several seasons if cleaned properly and handled gently. However, signs of cracking, warping, or mold indicate it’s time to replace them. Even high-quality trays should be inspected regularly to prevent disease spread or structural failure that could impact seedling health. Investing in sturdy, well-made trays reduces replacement frequency and supports reliable germination over multiple seasons.
Is it worth investing in trays with humidity domes?
Yes, trays with humidity domes can significantly improve germination rates by maintaining optimal moisture levels. This feature is especially helpful for starting seeds in cooler or less humid environments and can reduce the need for constant watering. However, they can also trap excess moisture, so good ventilation or venting is necessary to prevent mold. If you’re serious about high germination success or starting many seedlings at once, trays with humidity domes are a worthwhile investment.
What size tray is best for starting multiple types of seeds?
The ideal size depends on your seed varieties and space. Larger trays with many cells are suitable if you’re starting multiple types or varieties simultaneously, offering convenience and efficiency. For small or niche projects, smaller trays with fewer cells work well and allow for better management of individual seedlings. Consider also your available space and the future transplanting plan—larger trays require more handling but reduce transplant shock by minimizing root disturbance.
Can I reuse seed trays for multiple seasons without cleaning?
Reusing trays without proper cleaning is not advisable, as it can lead to disease buildup and poor seedling health. At the very least, trays should be washed with soap and water, and some gardeners disinfect them with diluted bleach or vinegar to eliminate pathogens. Proper cleaning extends the lifespan of the trays and ensures healthy, disease-free seedlings each season. Neglecting this step risks infecting your next batch of seeds and compromising your overall gardening success.
Conclusion
For most gardeners, the Epic Gardening Reusable 6-Cell Seed Starter Trays strike a balance between durability, ease of use, and environmental friendliness, making them the best overall choice. Those with limited space or starting small should consider the Gardzen 40 Cell BPA Free Tray for affordability and simplicity. Gardeners seeking long-term value and larger capacity will appreciate the MIXC 200-Cell Tray with Humidity Dome for high germination rates. Beginners will benefit from simpler, user-friendly options, while experienced growers may prefer premium, heavy-duty trays with advanced features. Choose the tray that best aligns with your gardening scale, budget, and commitment to ongoing success.
