Buying Guide
- Drainage considerations: No-drain-hole trays are great for drip systems and humidity control, but you may want some with drainage for certain crops. Consider your watering approach and whether you use drip mats or saucers.
- Size compatibility: Ensure the outer dimensions fit your benches, racks, or greenhouse shelves. Standard 1020 trays are common, but some sets use wider or deeper designs.
- Durability and reuse: Look for sturdy PS or high-quality plastic that resists bending, cracking, and warping under temperature fluctuations.
- Ventilation options: Trays with adjustable vents help regulate humidity and temperature during germination. If using humidity domes, check dome compatibility and fit.
- Modularity: Sets with stackable bases or modular components help maximize space and simplify storage between seasons.
- Content and accessories: Some kits include dibbers, dividers, or humidity domes that add value for seed starting and microgreens propagation.
- Environmental impact: Reusable trays reduce waste. Consider trays made from recyclable plastics and their overall lifecycle.
