Root Trainer Seed Tray 45 Cell Deep Propagation Tray

This 45 cell root trainer is designed for raising seeds and seedling of vegetables, trees and shrubs, providing deeper growing space to support the development of tap roots, particularly beneficial when growing beans and sweet peas.

Suitable for home gardeners, allotment growers and nursery propagation, it offers organised trays for seeds where reliable early growth and healthy establishment are important.

Root Trainer For Stronger Early Root Development

Shallow containers often cause roots to circle at the base, which can restrict growth and affect performance after transplanting. This deep seed tray encourages roots to grow downward rather than spiral, helping plant settle more confidently once moved into soil.

By supporting natural root structure from the beginning, young plant are better positioned to access water and nutrients as they continue to develop.

Deep Seed Tray With Generous Cell Volume

Each of the 45 cells holds 233ml (0.23 litres) of compost, giving larger seed and young plant the space they need before planting out. The structured 5 x 9 cell layout keeps spacing consistent, making watering and monitoring straightforward in greenhouse or outdoor setups.

This format works particularly well for vegetable, tree and shrub varieties that benefit from deeper rooting during propagation.

Reliable Drainage And Standalone Stability

A 15mm drainage hole at the base of every cell allows excess water to drain freely, helping maintain balanced moisture levels around the root zone.

Made from rigid PS polystyrene, the tray is self supporting and sits securely on benches or staging without requiring additional frames.
