Icopal Extensive Sedum Substrate is the ideal green roof growing medium for sedum species

BMI Canopia E Extensive Multi-Layer Substrate - For Extensive Green Roofs

Sedum species lend themselves very well to their use within extensive green roof systems. They are very drought tolerant, but do not thrive when the root zone is constantly wet. Therefore the BMI Canopia E Extensive Multi Layer Substrate is the ideal growing medium for sedum species, as it is able to hold sufficient water to enable healthy growth, yet it is free-draining.


Canopia E Extensive Multi Layer substrate is a vegetation base layer for extensive multi-layer green roofs and is also suitable for green roof areas with a pitch of 5 degrees or less.
