Buying Guide
What to consider when choosing cardboard trays for plants
- Tray size and cell count: Match tray dimensions to the available space and the number of plants you intend to start or move at once. Larger flats support more plants but require more space.
- Durability and weight handling: Heavier-duty corrugated trays resist bending when holding soil or pots and are better for transport. Consider edge-crush resistance and overall stiffness for stability during moving.
- Biodegradability and transplant ease: Seed-start kits with peat pots simplify transplanting by providing pots that can go directly into the ground. This reduces root disturbance and transplant shock.
- Moisture management: Drying versus moisture retention matters. Some trays are designed for quick drainage, while others tolerate moisture longer. Choose based on whether you start seeds indoors or move seedlings outdoors quickly.
- Compatibility with accessories: Look for trays that accommodate seedling cells, plant tags, and labeling to maintain organization during propagation.
Practical tips for use
- Label each tray or cell with a durable marker to track varieties and sowing dates.
- Line trays with a layer of waterproof barrier if you expect frequent watering to minimize leakage.
- For peat pots, consider pre-wetting the substrate to promote even moisture uptake.
