Allison Justice presents "The Effect of Air Velocity in Cannabis CEA" at CannMed 2026, covering cannabis CEA, airflow management, and canopy uniformity.
Airflow is a critical yet under-characterized factor in controlled environment cannabis production. This study evaluated the effects of targeted airflow manipulation on canopy uniformity, yield, and water use efficiency within an indoor cultivation system. Environmental parameters (temperature, relative humidity, and VPD) and plant responses were assessed across zones with differing airflow patterns. Optimized airflow reduced microclimate variability, resulting in improved canopy uniformity, increased yield, and more efficient water use. In contrast, excessive airflow increased the risk of mechanical damage, particularly in lignified tissues. These findings identify airflow management as a key driver of both productivity and resource efficiency in cannabis cultivation.
Learning Objectives:
⦿ Assess how different airflow velocities influence canopy uniformity, yield, and water use efficiency in controlled environment cultivation systems
⦿ Identify how air velocity can be used as a crop steering tool
Allison Justice, PhD is the Founder and CEO of The Hemp Mine and the Cannabis Research Center and Coalition (CRC), and a leading expert in cannabis cultivation and research. She holds a PhD in Plant and Environmental Science from Clemson University and has advanced the field through her research on lighting, drying, and curing. At The Hemp Mine she oversees a 20-acre hemp farm and product manufacturing operation where her cultivation research is applied directly. As a fourth generation farmer, Dr. Justice focuses on making science practical for improved sustainability and efficiency.
This presentation was given at the CannMed 2026 Innovation & Collaboration Summit, held June 15-18 at the Hyatt Regency Lake Tahoe Resort. Visit cannmedevents.com to learn more.
