Cork Substrate

Cork Substrate is made of ground cork bark and because of its light and hydrophobic nature, works perfectly as a substrate for orchids or other epiphytes. Cork bark can take 10-30 years to break down, meaning it will likely last the lifetime of your plant! Use in your own substrate mix recipe to make a great lightweight mix for aroids and other rare exotic plants. Choose from medium, course, or ungraded.Price is per Quart.
