A new resource was recently released to help licensed producers optimize their indoor cannabis production, and it looks to be a fantastic resource for growers and students looking to tackle any aspect of growing. The Handbook of Cannabis Production in Controlled Environments, edited by Dr. Youbin Zheng, professor at the University of Guelph, showcases fantastic research from experts within the cannabis sector. 

Here’s a brief breakdown:

Chapter 1: Introduction
An introduction to basic biology, phytochemical constituents, and controlled environment production of cannabis.

Chapter 2: Growing Facilities and Environmental Control
An overview of the science and technology behind the control of temperature, humidity, carbon dioxide, air distribution and lighting, and discusses how these key environment factors affect cannabis growth and development. 

Chapter 3: Genetics and Plant Breeding of Cannabis sativa for Controlled Environment Production
This section outlines cannabis genetics and breeding. 

Chapter 4: Cannabis Propagation
This section is about propagation by seeds, stem cuttings and in vitro technologies.

Chapter 5: Rootzone Management in Cannabis Production
Discusses water sources, water quality, water and nutrient solution treatments, nutrition and fertilization, growing media and their selection, different rootzones used in cannabis cultivation and integrated rootzone management for different cultivation systems.

Chapter 6: Lighting and CO2 in Cannabis Production
This chapter discusses how CO2 affects cannabis production and should be supplied during cultivation.

Chapter 7: Canopy Management
Reviews plant canopy management from the viewpoint of plant physiology, and describes how to manage canopies for stock plants for production of cuttings, and to manage vegetative and flowering plants. 

Chapter 8: Management of Diseases on Cannabis in Controlled Environment Production
This discusses general plant pathology, disease management principles and specific disease control practices for cannabis production.

Chapter 9: Management of Insect Pests on Cannabis in Controlled Environment Production
This introduces the basic concepts of IPM for controlled environment cannabis cultivation, and the biology and management strategies for major insect pests of

Chapter 10: Harvest and Post-Harvest
This covers when and how to harvest, post-harvest trimming, drying, curing and storage.
