Discription

Ed Rosenthal's legacy handbook contains the foundational knowledge, tools, and methods to enable you to grow great marijuana—inside and out.  All aspects of cultivation are covered, from the selection of varieties, setting up of the garden, through each stage of plant growth all the way to harvesting. Use efficient technology and save time, labor, and energy. Photographs throughout clarify instructions and show the stunning results possible by following Ed's growing advice. This classic guide was groundbreaking when it was first released in 2010. For the very latest in technologies, tips, and techniques, including advances in LED lighting, garden design, genetics, and sustainability, the author recommends his new title: Cannabis Grower's Handbook, just released in October 2021.
