Alongside high quality peat containing RAL-certified substrat compost and RAL-certified wood fibers, Brill BIO substrates also contain Brill's unique coconut based renewable resource: our CocoSol supports the flow quality and improves air capacity, structure stability and rewetting. Our CocoDrain is a mix of coconut chips, coconut fibers and fine coconut material developed and produced by Brill. It increases the substrate's structural stability and improves water supply and drainage.
All BIO substrates contain an organic fertilizer and trace elements. They have an adjusted structure and an adequate pH value.
