THE ‘ECU’ ADVANTAGE

We are not just another “worm farm”. Our affiliates have a very unique and clean production process for creating earthworm castings.  We are not in the business of breeding worms for production, far from it!

WE ARE A GREEN GROUP

Through a recycling initiative to the world’s largest worm wholesaler, we recycle, process and package what was a wasted product now available for use. We invite you to protect and enhance our environment by growing organically with our product.
