SOPRAFLOR X is a growing medium formulated for extensive non-irrigated and low-maintenance SOPRANATURE® systems. SOPRAFLOR X has a high percentage (70%) of mineral aggregates. This prevents the substrate from compacting in the long term while improving air porosity and plant anchoring. SOPRAFLOR I is a growing medium formulated for intensive and semi-intensive SOPRANATURE® green roofs and plaza deck/roof gardens. SOPRAFLOR I has a high percentage (55%) of mineral aggregates. This prevents the substrate from compacting in the long term while improving air porosity and plant anchoring.
