Deep 72 Cell Seedling Trays With Big Cells
The Deep 72 Cell Seedling Trays by RooTrimmer Store feature a 21.25″ × 11″ footprint with a 2.36″ cell depth, designed to fit standard 1020 trays that reach near 2.5 inches in height. The bigger cells provide more soil volume, supporting stronger subroot development and longer time in the tray before transplanting. This can help seedlings access water and nutrients more consistently, reducing transplant shock. The trays are versatile for starting a wide range of plants, including vegetables, flowering plants, herbs, and even fruit seedlings that require more space per plant. Suitable for bottom watering setups to optimize moisture levels.

Buying Guide
When choosing a 72 cell propagation tray, consider the following factors to match your gardening goals:
- Cell size and depth: Deeper cells provide more soil volume for robust root systems, which can improve plant resilience during transplanting. However, smaller cells save space in compact setups and may require more frequent watering.
- Tray compatibility: Ensure the tray fits standard 1020 flats if you plan to stack or move between setups. Height compatibility helps prevent crowding under lights or in racks.
- Watering system: Decide between bottom watering, self-watering inserts, or traditional top-watering trays. Self-watering options reduce risk of overwatering and simplify moisture management.
- Materials and durability: Reusable trays save costs over time but require proper cleaning to prevent disease buildup. Durable trays withstand repeated use in busy propagation spaces.
- Auxiliary tools: Dibbers, labels, domes, and grow lights can streamline germination and early growth. Kits that include these tools reduce shopping lists and setup time.
- Light integration: If starting indoors, options with built-in grow lights can accelerate growth but may require more electricity and space planning.
- Organization features: Programs or diagrams for seed labeling help keep varieties separated and tracked through germination and early growth phases.
Performance considerations across these options include moisture retention stability, ease of transplanting, and how well trays balance with common greenhouse or indoor setups. For beginners, all-in-one kits with clear moisture control and labeling support can reduce trial-and-error. For experienced growers, durable, reusable trays with modular add-ons (like dibbers and markers) offer long-term value. The right choice depends on your space, the crops you grow, and how hands-on you want to be during germination and early growth.
