During propagation
Matching individual components and accessories: STP QP 54R Propagation Tray – 54 Cells · Tall STP Propagation Cover – 12 cm Usable Height.
Match light, temperature and sowing depth to the species. Cell size and root development determine the appropriate transplanting stage.
If water is urgently needed, water the cell tray gently from above. For crops with low water demand, removing the mat can reduce capillary supply; continue checking moisture.
Choose water quality and nutrient supply according to the species and growing medium. Fertiliser is not included; follow the instructions of the specific product used.
Handling guidance
- Keep water-bearing parts away from electrical and electronic equipment; escaping water can cause electric shock or damage.
- Always carry filled cell trays with their base tray underneath to prevent bending or breakage.
- Monitor water level and growing-medium moisture. Excessive water levels can cause waterlogging and root damage.
- Strong sunlight can deform black components.
Cleaning and storage
Clean the base tray and capillary filter mat according to dirt and temperature, at least every three weeks, using clear water or neutral soap. Warm standing water can encourage algae, fungi and germs.
Remove plant and growing-medium residues. Clean and dry before longer storage; check for damage and clear bottom openings before reuse.
