Being Clean Green® certified means that we meet national and international organic, plant-based, regenerative, and sustainable standards. When you purchase a C4 product, you can feel confident that you’re getting the highest quality cannabis.
Extensive lab testing
and facility inspection through our annual Clean Green re-certification ensures that our customers are getting the best product grown with the best practices.
Innovative Integrated Pest Management (IPM) allows us to control pests at the microscopic level, eliminating the need for chemical pesticides.
We’re reducing our carbon footprint by decreasing single use plastics in cultivation, implementing regenerative agriculture practices through composting, and using more energy efficient methods in growing and harvesting.
We grow a finer flower, naturally. Our living soil is biologically active and nutrient-dense. Creating the cleanest product from soil, to seed, to sell.
The Clean Green Certified® Program uses a federally licensed agricultural lab, the same lab used for National Organic Program testing.
These labs ensure not only the highest standards for members, but the highest quality products for consumers.
From the start, C4 partnered with Bio 365 for our living soil. We believe the quality of soil determines the quality of cannabis. Through our living soil, zero-chemical pesticide control, and all natural nutrients, we grow a superior cannabis product.
Responsibly grown with the highest Clean Green® Certification standards, our cannabis tests 5%-6% higher in THC levels, on average, than comparable strains nationwide. This is a testament to our slow grow and curing methods.
C4’s light weight packaging reduces the weight of our products, reducing fuel use and our carbon footprint. Additionally, our pop top containers are fully recyclable.
From lights to cooling, C4 is committed to reducing our energy use. Part of our Clean Green® Certification, our dedication to reducing our carbon footprint is rare in an industry known to overuse and abuse energy resources.
Our soil gets recycled through community compost. All of our containers used for cultivation are re-used as many times as possible, reducing plastic waste.
C4 was the very first cultivator in Missouri to be Clean Green® Certified, and we’ve been certified since our very first harvest in 2020.
