Our Extensive range of substrates are fully tested to FLL requirements.
Description
Extensive substrate is a low maintenance growing medium for green roofs and wildflower areas designed to support the growth of sedums, mosses, and wildflowers. This sustainable and hard wearing material comprises porous, natural pumice, for drainage as well as PAS100 compost for balanced nutrient content and water retention. This material can be blended to order with varying sizes of pumice (2-10mm or 8-15mm) and composted bark for wildflower growth.
