The design confines soil, fertilizer, and water, simplifying care and cleanup. Lightweight and easy to wash, these trays support indoor and outdoor use, from windowsill microgreens to vegetable seedlings in a greenhouse.
Who it’s for: new or budget-conscious gardeners needing multiple trays without frequent replacement. Why chosen: strong, reusable construction plus a generous size for larger seed flats. Caution: check compatibility with your shelving or rack system, as size is relatively large for compact setups.
Living Whole Foods 10 Plant Trays (No Drain Holes)
Best for growers who prefer a no-drain-hole design to simplify watering and use as a drip tray or hydroponic base. The 10-tray set measures roughly 20″ by 10″ with a top surface around 21″ by 11″, providing ample space for seedlings, microgreens, or wheatgrass. The absence of drainage holes helps contain moisture, making these trays suitable for hydroponic systems or drip irrigation setups.
Who it’s for: hydroponic enthusiasts or small-scale greenhouse growers who want a flat, leak-free working surface. Why chosen: wide, hole-free surface offers versatile moisture management. Caution: no drain holes means you’ll rely on external drainage or external wicking to avoid overwatering in some systems.

They’re suitable as bases under individual pots or larger seedling flats.
Who it’s for: homeowners seeking a durable, heavy-duty option to prevent messes under pots. Why chosen: high load-bearing capacity and thick material. Caution: without drainage holes, avoid excessive water buildup by pairing with proper potting practices or external drainage.
YoleShy 10 Pack Seed Starter Trays
Best for germination-focused projects and microgreens. The 10 trays are without holes, featuring a thickened design and deeper ridges for better water management. Each tray measures 14.5″ x 9″ x 2.2″ and is suitable for windowsill and greenhouse use. The sturdy build supports consistent moisture for seeds and young plants without leakage.
Who it’s for: gardeners prioritizing strong water retention and a compact footprint. Why chosen: thickened construction and ridges improve durability and root-zone stability. Caution: smaller surface area than some larger trays may limit space for bigger seed flats or several crops per tray.

Who it’s for: indoor gardeners who want mess-free seed starting and easy cleanup. Why chosen: no-drain-hole design simplifies maintenance. Caution: if you need to manage excess water, you’ll need an external drainage plan or separate saucers under trays.
Buying Guide
Key considerations for selecting plastic seedling trays:
- Size and layout: Choose trays that fit your space, racks, and available light. Larger trays support more seedlings per flat, while smaller sizes suit compact setups.
- Drainage: Draining holes support wet conditions; no-hole designs reduce mess but require careful water management.
- Material quality: Look for durable, UV-stable plastics that resist cracking from temperature changes and repeated use.
- Depth and cell count: Deeper trays and more cells support longer germination and root development for certain crops.
- Reusability and cleaning: Reusable trays save costs but require easy cleaning to prevent disease transfer between crops.
- Versatility: Some trays double as drip trays, hydroponic bases, or microgreen platforms—evaluate how you’ll use them beyond seed starting.
Practical tips for choosing
- For beginners: start with a multi-pack of larger trays to cover varied crops and space configurations.
- For hydroponics: consider trays without holes or those that pair well with your reservoirs and stands.
- For microgreens: look for trays with shallow depths and uniform ridges to support consistent growth.
