This is the proprietary blend of bedding / potting soil recommended for planting in a BioHaven. It is made up of peat, powdered bark and hydrophilic foam. The key properties of BioMix are: it is light and won’t cause negative buoyancy issues, and it will wick water up to 7 inches (peat will go to 5”). This allows the plants on a BioHaven to obtain all their water from below. (Additional benefits are: it is weed-free, it will not fall through the matrix).
