Key Features
1. Deep Cells for Strong, Vertical Root Growth
Most 60‑cell trays feature 13–15 cm deep cells designed to drive roots downward rather than outward. This prevents root circling and promotes healthier, transplant‑ready plants.

Benefits of Using a Root Trainer Tray
1. Higher Germination & Better Early Growth
The deep cell format ensures seedlings have the moisture, oxygen and space they need for fast, even germination.
2. Stronger Plants & Reduced Transplant Shock
Vertical root growth and air-pruned root tips create robust root systems that transplant exceptionally well.
3. More Plants in Less Space
Its compact footprint maximises propagation output without requiring a large greenhouse or bench area.
4. Cost‑Effective & Long‑Lasting
Reusable trays save money over time. Many users get years of propagation from a single unit.

How to Use the Root Trainer 60 Cell Tray
1. Fill the Cells
Use a fine-textured seed‑starting mix. Gently tamp so each cell is evenly filled.
2. Sow Seeds
Follow the seed packet’s recommended depth. Larger seeds (beans, sweet peas, sunflowers) particularly benefit from deeper cells.
3. Water Carefully
Use a spray mister or bottom‑watering to prevent soil compaction.
4. Provide Adequate Light
A bright windowsill, greenhouse bench or LED grow light setup works well.
5. Transplant Gently
Push up from the bottom drainage hole to pop out each plug. This avoids root trauma and ensures excellent establishment.
