Best Large Open Tray – Mr. Pen 5-Pack Growing Trays

The Mr. Pen trays offer a spacious, open format for gardeners who prefer flexibility over individual cells. At 17 by 10 inches, they work well as seed starting trays for vegetables, sprouts, microgreens, potting projects, and use with heat mats or humidity domes.

Key Buying Factors for Seed Starting Trays for Vegetables

Cell Size and Capacity

Small cells work well for lettuce, herbs, onions, and other seedlings that will be transplanted young. Larger cells are better for tomatoes, peppers, cucumbers, squash, and seedlings that may remain in their trays longer. High-capacity kits save space but require closer monitoring because small cells dry out faster.

Drainage and Water Management

Look for drainage holes and a separate base tray that catches excess water. Consistent moisture is important, but saturated soil can encourage root problems. A humidity dome helps retain moisture during germination; remove or vent it as seedlings emerge to improve airflow.

Durability and Reuse

Thicker plastic trays are generally easier to clean and reuse. If you plan to start seeds every year, prioritize sturdy construction, washable surfaces, and trays that resist bending when filled with wet soil. Lightweight multi-packs can be useful, but they may be better suited to occasional use.

Included Accessories

Plant labels, humidity domes, base trays, peat pellets, and grow lights can reduce the need for separate purchases. Check exactly what each kit includes, especially if you need a complete setup rather than empty cell trays.

Who Should Buy Which Seed Starting Trays for Vegetables?

Choose a reusable 36-cell tray if you grow a modest number of vegetable seedlings and want a durable, organized setup. Large 120- or 200-cell kits make more sense for gardeners starting many plants or several varieties at once. Multi-packs are useful for succession planting and sharing seedlings with other gardeners.

If your growing area is dry, cool, or prone to inconsistent moisture, choose a kit with humidity domes. For a windowsill or room with limited sunlight, a tray with built-in LED lights may offer a more dependable start. Finally, beginners who want fewer separate components may prefer a kit that includes peat pellets, labels, a base tray, or other ready-to-use accessories.
