Mr. Pen Plastic Growing Trays, 5-Pack

The Mr. Pen seedling trays are sold in a five-pack, making them suitable for multi-crop starts or batch propagation. Each tray measures 17 by 10 inches with a shallow 2.4-inch depth, offering ample surface area for seed germination and early root development. The trays are described as sturdy and reusable, designed to contain soil, fertilizer, and water for easier management. Lightweight handling and easy cleaning are noted benefits, which can reduce waste and lower long-term costs for hobbyists and small-scale growers.
Features highlighted include: a 5-pack offer, durable plastic construction, reuse-friendly design, containment of soil and moisture, and straightforward cleaning. The broad footprint supports larger seedling batches and compatible spacing for standard greenhouse setups or windowsill propagation. While the no-drain-hole design isn’t explicitly stated, the emphasis on moisture containment suggests ease of use for indoor setups where controlled watering is preferred.
10 Plant Growing Trays (No Drain Holes) – 20″ x 10″

These no-drain-hole trays offer a large, low-profile surface suitable for seed starting, hydroponics, microgreens, or wheatgrass. Each tray measures roughly 21 by 11 inches at the top with a bottom width near 20 by 10 inches, providing substantial area for many seedlings and generous root development. The lack of drainage holes is designed to support drip systems or simple moisture retention, reducing runoff and keeping work surfaces cleaner in home gardens or indoor gardens.
Key considerations include: a 10-tray bundle suitable for batch propagation, no-drain-hole design to accommodate drip watering or hydroponic setups, and a large usable area for dense planting. The absence of drainage holes means you’ll need to manage excess moisture via external saucers or a careful watering routine. Durability and ease of cleaning are typical advantages for these plastic trays, though users should be mindful of potential over-watering risks in humid indoor environments.
EXTYQWC 10 Plant Growing Trays (No Drain Holes)

EXTYQWC offers a 10-pack of no-hole seedling trays, sized at 17 by 11 inches. Constructed for durability, these trays emphasize a no-hole design to minimize mess and simplify maintenance. Their stated versatility covers seed starting, microgreens, bonsai, and indoor gardening applications, making them appropriate for both hobbyists and greenhouse operators. The absence of drain holes makes them a clean-fit for drip or capillary irrigation approaches while providing a stable, reusable option for repeated seasons.
Considerations include: hole-free design for cleaner operations, a roomy footprint for single or multi-crop setups, and the potential to reduce ancillary saucer use. The emphasis on repeat use aligns with sustainability goals, though gardeners should plan a controlled watering strategy to prevent waterlogging in compact soils.
YoleShy 10 Pack Seed Starter Tray Reusable Plastic

YoleShy provides a 10-pack of thickened, durable seed starter trays designed to support germination and microgreen growth. Each tray measures 14.5 by 9 inches with a depth around 2.2 inches. The trays are described as thicker than standard options, featuring reinforced ridges along the perimeter to improve bearing capacity. The without-hole design helps with concentrated watering and reduces spillage on work surfaces, making them a practical option for windowsills and seed-starting stations.
Important factors include: enhanced thickness for durability, deeper side ridges for stability, and ample area for seedling root systems. The no-drain-hole approach suits controlled watering methods, though it requires careful moisture management to prevent overwatering in compact soils or humid environments.
XCRUI 10Pack Seed Starting Trays

XCRUI’s 10-pack provides a no-hole seed starting tray option with a 14.5 by 9 inch footprint and a 2.2 inch depth. The design emphasizes durability, thickened plastic, and reinforced edges to support repeated use across seasons. The no-leaks feature helps maintain a tidy grow space by retaining moisture within the tray and reducing the need for extra saucers. Gardeners with hydroponic or soil-based setups may appreciate the tray’s reliability for starting seeds and supporting root development.
Key points to weigh include: sturdy construction for longevity, a large interior area for multiple seed types, and a no-drain-hole design to suit drip irrigation. The trade-off is the need for a precise watering plan to avoid standing water, especially in humid interiors or when growing moisture-loving crops.
The Hydroponic City Seed Starter Trays, 216-Cell

The Hydroponic City offers a compact seed starter system with 216 cells across 36 trays (6 cells per tray). Each cell measures 1.5 inches square and 2.25 inches deep, designed to promote robust root development and strong seedling starts. The high cell count supports growing many seedlings per square foot, which is beneficial for trays in tight greenhouse spaces or apartment setups. The trays are described as durable and reusable, aligning with sustainable gardening practices.
Considerations include: very high seeding density and modular tray design, which suits commercial or serious hobbyist environments. The smaller cell size supports a wide variety of seeds, but it requires careful labeling and organization to manage dozens of seed types. Reuse and resilient construction help justify ongoing use across growing seasons.
Buying Guide: Key Purchase Considerations
- Drainage and moisture management: Decide between trays with drain holes for seedlings that require good drainage (to prevent root rot) and no-hole designs for drip irrigation, moisture retention, or microgreens. Pair with appropriate saucers or trays for catchment if needed.
- Size and footprint: Match tray dimensions to your growing space. Larger trays support more seeds per batch, while smaller trays fit compact windowsills or indoor shelves. Consider whether you need a single large tray or multiple smaller modules.
- Durability and reuse: Thickened plastic, reinforced edges, and robust materials extend life across seasons. Reusable trays reduce waste and long-term costs, but ensure they’re easy to clean and resistant to warping from heat.
- Cell count and seed type: Higher cell counts are useful for nursery-style setups and microgreens, while fewer, larger cells work well for bigger plants with longer germination times. Consider whether you are starting herbs, vegetables, flowers, or wheatgrass.
- Compatibility with hydroponics: If you use hydroponic systems, trays designed for water containment or drip irrigation can streamline maintenance and minimize spills. No-hole trays may pair well with capillary mats or reservoirs.
- Portability and storage: Lightweight trays are easy to move for space management and seasonal rotation. Stackable designs save storage space when not in use.
- Cleanability and sanitize-ability: Smooth surfaces and rounded corners reduce dirt buildup and simplify cleaning between crops, reducing disease risk in successive rounds.
