Fill the cells evenly with a propagation medium suited to the plant species. Keep the base openings unobstructed.
- Sow or insert cuttings
Add seed or prepared cuttings. Choose sowing depth, covering and spacing according to the species.
- Water in
Moisten the medium evenly and allow excess water to drain. Do not leave the tray permanently standing in water.
- Monitor the plants

Choose the right BTP model
Within the same tray footprint, the models differ in cell count, width and depth. Choose according to the species and time until potting on. Base openings, spacing feet and the angled perforated base support drainage; the supporting surface must allow water to escape.
Handling guidance
- Support filled trays securely and do not pull individual cells.
- Keep drainage clear and avoid standing water.
Cleaning and storage
After growing, remove medium and root residues, clean with water and store dry. Check for cracks before reuse.
