GET A "GROWER'S GUIDE"
Get the book that launched the Website! In August 2018, Green Harvest Press published Dr. MJ Coco’s book, Coco for Cannabis: A Grower’s Guide. On September 1st, 2018, we first launched this site.
We believe that knowledge should be shared freely, so we made the information in the book available in articles and tutorials on the site. The book is a consolidated guide, but it is not required. You can learn all the keys of growing cannabis in coco here on the website.
