Boughton EX Light

Boughton EX Light, Extra lightweight Green Roof Substrate mixture makes it an ideal growing media for green roofs where weight loading is an issue. Its low bulk density, even at field capacity, allows it to be installed to a much deeper depth than conventional extensive substrates, improving the growing environment for plants. Its free draining nature prevents the substrate from becoming saturated, making it ideal for drought tolerant plants.
