Description
This 45 cell root trainer tray is purpose-built for raising seeds and young seedlings of vegetables, trees, and shrubs. The deep cell design provides extended growing space that supports the development of strong tap roots, making it especially well suited to crops such as beans and sweet peas.
Ideal for home gardeners, allotment growers, and professional nursery propagation, this tray keeps seeds organised and evenly spaced, helping ensure reliable early growth and healthy plant establishment.
Encourages Stronger Early Root Development
Traditional shallow seed trays can cause roots to spiral at the base, restricting growth and reducing performance after transplanting. This deep seed tray encourages roots to grow downward instead of circling, allowing plants to establish more quickly and confidently once planted out.
By promoting a natural root structure from the outset, young plants are better able to access water and nutrients as they continue to grow.
Deep Cells with Generous Compost Capacity
Each of the 45 cells holds 233ml (0.23 litres) of compost, providing ample room for larger seeds and developing seedlings before transplanting. The structured 5 × 9 cell layout ensures consistent spacing, making watering, inspection, and plant management simple in greenhouse, polytunnel, or outdoor growing environments.
This format is particularly effective for vegetable, tree, and shrub varieties that benefit from deeper rooting during propagation.
Efficient Drainage and Stable, Self-Supporting Design
Every cell features a 15mm drainage hole at the base, allowing excess water to drain freely and helping maintain balanced moisture levels around the root zone.
Manufactured from rigid PS polystyrene, the tray is fully self-supporting and sits securely on benches or staging without the need for additional support frames.
