NextSource frass is a completely natural, premium soil improver. Born from our circular insect farming process, this frass is a by-product of recycling waste from local breweries & flour mills. Rich in chitin with a balanced 5-2-2 NPK, it provides all the essential nutrients for plant growth and development.
Alongside all the essential macronutrients, our frass is enhanced with additional chitin. This is a natural compound found in insect exoskeleton material. Research shows that chitin acts like a signal that triggers natural plant defence responses, prompting thicker stems and bigger leaves.
Our frass is sustainably made and sustainably packaged at Home Farm, offering a completely natural way to build a thriving growing environment in your garden.
