ORCA uses a new production method to create healthy, viable spores. Once germinated this beneficial fungus will increase your plants’ uptake of nutrients and water resulting in a higher yield and more flowering sites. With ORCA mycorrhizal fungus you will also offers protection for plants from transplant shock and drought stress. Most of the top nurseries and farms now use mycorrhizal fungus to increase yields and decrease fertilizer and water costs. This symbiotic relationship between host plant and fungus has existed since plants first colonized land 450 million years ago.
