Welcome to your site! This is your homepage, which is what most visitors will see when they come to your site for the first time.


We supply the products and techniques to help you increase yields, improve quality and reduce cost while transitioning to biological management. Contact us about consultations and microbe assessments. Through microscopy we analyze the biology in your soil and assess your specific needs to allow your plants to express their full genetic potential.


We offer a complete line of biological amendments.  Our ingredients are obsessively sourced in small batches,  to insure a quality product we check every batch microscopically for the balance of microbes we strive to achieve.

Contact us about our local beneficial nematodes, protozoan infusion kits, and other amendments.
