Grassroots Science™


The Cannabis Horticultural Association (CHA) was formed early 2016 in Humboldt County, California.  It is peer network of earth scientists that study the fields of Botany, Plant Physiology, Plant Genetics, Soil Science, Chemistry, BioChemistry, Entomology and Plant Pathology. The CHA offers in depth horticultural knowledge covering management practices for Organic Farming, Biocontrols and Integrated Pest Management. We strive for the Cannabis Horticultural Association to be an authoritative and first choice for people seeking to learn how to cultivate clean, high grade cannabis through the objective information and education on sustainable and regenerative management practices. We are cultivating a new industry standard for ecological horticulture.



The mission of the CHA is to study the horticultural science of cannabis and to conduct, promote and encourage research and education for ecologically sound management practices and to facilitate cooperation and knowledge transfer on a global scale through its research, memberships and scientific structure. Another aspect is fostering symbiotic partnerships with the horticulture industry and other institutions, agencies, organizations, businesses and communities.

We are building an online horticultural research center. This resource center is the hub for which we disseminate pertinent research we collect through our memberships, experiments, case studies, research, reviews and publications. This research center houses a community forum which boasts the world's first cannabis forum to be hosted by scientists as administrators.

Through our peer network of scientists, advisors and industry experts, we provide feedback to our community and address their personal questions. This allows us to maintain the highest standards of cultivation with expert advice and personalized service. Our website offers a management tool towards a sustainable platform for the entire industry.   We strive to provide plant management data for the small home gardener all the way up to commercial farming.
