Buying Guide: Key Considerations For Greenhouse Trays
- Drainage: Decide between trays with drainage holes (for automatic runoff) and no-drain options (for controlled watering). In greenhouses, no-hole trays work well with capillary mats or drip systems.
- Size and capacity: Match tray dimensions to your bench space and the number of cells or pots you plan to manage at once.
- Durability and reuse: Look for sturdy plastics that resist cracking and are easy to clean. Reusable trays save money over time.
- Compatibility: Consider whether trays fit standard pot sizes (like 24-cell configurations) and whether they support stackability or easy transport.
- Water management: For self-watering kits or humidity-controlled trays, verify features like mats, reservoirs, or domes that help regulate moisture.
- Maintenance: Favor trays that are easy to wash and dry to prevent disease and algae growth between seasons.
