Depending on the plant species, fill the remaining container with a COMPO BIO or COMPO SANA® potting soil. As a planting medium for hydroculture and semiculture, suitable for plants that have grown beyond the young plant stage. Preparation: For a plant that has been grown in soil, carefully shake off the loose soil. Leave the densely rooted soil ball as it is to avoid injury to the roots. If the plant has been grown in a hydroponic system, first carefully free the roots from the old substrate. Clean a previously used pot thoroughly before planting. Planting: Fill a quarter of the pot with the COMPO BIO GRANUPLANT® drainage and plant granules. Place the plant in the pot and add more granules around the plant to stabilize it. Fertilize: Water the plant with a low-dose nutrient solution. Use the COMPO COMPLETE plant fertiliser with half the dose, but twice as often. Note: It is important to make sure that the root ball is not in water at maximum water level. It is advisable to use a water level indicator.To cover the top layer of soil in the planterAs the top layer of the planter, we recommend spreading a 2-3 cm thick layer of COMPO BIO GRANUPLANT® drainage and planting granules evenly over the soil. For plants that are sensitive to waterlogging, we recommend adding up to 25% of the COMPO BIO GRANUPLANT® drainage and plant granules to the soil.
