Packaging consists of > 80% PCR recycled plastic with Blue Angel ecolabel. Instructions for use: As a drainage layer. We recommend filling the plant container with COMPO BIO GRANUPLANT® drainage and planting granules to a volume of one-quarter to one-third as the bottom layer. Fill the remaining space in the container with COMPO BIO or COMPO SANA® potting soil, depending on the plant type. Suitable as a planting medium for hydroponics and semi-hydroponics. Suitable for plants that have grown beyond the seedling stage. Preparation: For plants grown in soil, gently shake off the loose soil. Leave the densely rooted root ball intact to avoid damaging the roots. If the plant was grown hydroponically, first carefully remove the roots from the old substrate. Thoroughly clean any previously used pot before planting. Planting: Fill the pot one-quarter full with COMPO BIO GRANUPLANT® drainage and planting granules. Place the plant in the pot and add more granules around the plant for stabilization. Fertilizing: Water the plant with a diluted nutrient solution. Use COMPO COMPLETE plant fertilizer at half the recommended dose, but twice as often. Note: Ensure that the root ball is not submerged when the water level is at maximum. The use of a water level indicator is recommended. As a cover for the top layer of soil in the planter: As the top layer in the planter, we recommend evenly distributing a 2-3 cm thick layer of COMPO BIO GRANUPLANT® drainage and planting granules over the soil. As a soil mix: For plants that are sensitive to waterlogging, we recommend mixing up to 25% of COMPO BIO GRANUPLANT® drainage and planting granules into the soil. Application period: February to November. Active ingredients: high-quality, 100% natural pumice granules. Store in a cool, dry place. Reseal opened packages tightly. Do not expose to direct sunlight.
