Buying Guide
- Cell size and depth: Deeper cells promote robust root systems, while shallower cells speed up germination. Consider the plant types you grow and transplant timing to pick the right depth.
- Material quality and durability: Thick, high-quality plastics resist cracking and warping. Reusable trays save money over time and reduce waste.
- Tray compatibility: Check if the plug trays fit common 1020 or shallow 1020 trays to ensure a smooth workflow and easy transplanting.
- Versatility: If you grow a mix of crops, choose trays with a variety of cell counts or a system that accommodates different seed sizes and transplant schedules.
- Mobility and storage: Consider stackability and weight. Lightweight trays save effort when moving seedlings, while sturdy trays withstand frequent use.
- Drainage and moisture control: Trays with effective drainage or moisture-balancing features help prevent overwatering and root rot, especially in hydroponic or warm environments.
- Repairability and repair options: Look for trays that are easy to clean and repair, and that offer replacement parts or spare inserts when needed.
- Cost and value: Higher initial cost may be justified by longer lifespan and lower replacement frequency. Weigh cost against expected seed-starting volume.
- Environmental impact: Reusable plastics and durable designs reduce waste. Consider products that are recyclable at end of life or come from brands with sustainable practices.
