Buying Guide
Key considerations when selecting plastic seed starting cells:
- Cell size and depth: Larger cells (about 1.5″ x 2.0″ or similar) support robust root systems. Smaller cells save space but may require transplanting sooner.
- Drainage and moisture control: Look for drain holes and built-in moisture management features to prevent overwatering and fungal issues.
- Durability and reuse: Polypropylene or sturdy plastic trays withstand repeated seasons. Consider whether the kit includes a reusable dome or base.
- Visibility: Clear trays or observation-friendly designs help monitor germination and root health without disturbing seedlings.
- Expansion potential: For larger projects, high-capacity trays (e.g., 216 cells) can streamline cultivation but require more space.
- Transplant ease: Flexible or soft-cell designs reduce root disturbance during transplantation, supporting seedling survival.
- Maintenance: Dishwasher-safe components simplify cleaning between seasons for certain Burpee models.
- Compatibility with seeds: Ensure tray size accommodates the seeds you plan to start, from microgreens to larger herbs and vegetables.
In summary, choose a seed starting system that aligns with your space, seed variety, and transplant goals. For beginners, a compact 6- or 16-cell tray with clear visibility and straightforward drainage can be ideal. For larger projects or classrooms, high-capacity options provide efficiency and versatility, while premium reusable trays emphasize longevity and sustainability.
