- Drainage and water management: Drain holes and raised channels help prevent root rot and ensure even moisture distribution.
- Durability and reuse: Reusable plastic trays reduce waste and costs over time. Check for warp resistance in sun exposure.
- Ease of transplanting: Pop-out or flexible cells minimize root disturbance during transplanting.
- Ventilation and humidity control: Humidity domes or adjustable vents help stabilize germination conditions for sensitive seeds.
- Cleaning and maintenance: Dishwasher-safe or easy-to-clean trays simplify seasonal reuse.
