The World's Premier Website for Cannabis Horticultural Science

 ecological & Organic solutions for high grade cannabis

We are the world's first horticultural association dedicated to the cultivation of cannabis.  Our goal is to share the latest, cutting edge science on sustainable practices for our brand of ecological horticulture. Our membership's digital resource center provides a clear platform for the sustainable production of clean, high grade cannabis. Members will have access to horticultural knowledge on the use of biological controls, integrated pest management, integrated nutrient management and support for understanding organic methodologies used in traditional agricultural practices. Our public site provides general information and horticultural blog on the latest topics related to cannabis horticultural science. The CHA is being built as the authoritative and first choice for people seeking research based, objective information and education on sustainable and regenerative management practices for cannabis. We encourage all industry professionals and hobbyists to join and take part in expanding our platform of ecologically sound horticulture.

Thank you for what you are doing! I very well could have lost my entire crop had it not been for your efforts. Keep up the great work!!
