Cannabis Lighting Research Reveals Cultivation Practices Improving

<![CDATA[For the past five years, Cannabis Business Times has conducted research to determine how growers are using lighting in their indoor and greenhouse facilities. With five years of data, the 2020 State of the Lighting Market Report revealed interesting insights about the cannabis cultivation market, specifically which lighting types growers are using for different stages of growth, which cultivation metrics they’re tracking and more. One noteworthy finding from the research, conducted by third-party firm Readex Research and made possible with support from Fluence by OSRAM, was that cultivators are increasingly using LED lighting in all stages of plant growth. From 2016 to 2020, LED usage increased by 42 percentage points in propagation, 41 percentage points in veg, and 37 percentage points in flowering, which represented the strongest growth when compared with other lighting types.James Eaves, director of indoor agriculture at digital electricity company VoltServer and professor at Université Laval in Quebec, Canada, said this struck him when he was reading the 2020 State of the Lighting Market Report. “From my own interaction with growers, I see people adopting LEDs, but it’s still a lot of HPS, which especially in flower, is still strongly embraced by growers,” Eaves said. “I think if they are high enough intensity that LEDs are a good replacement for HPS.” More than half (52%) of participants in CBT’s 2020 lighting research said they use LEDs in the flowering stage, and 40% said they use HPS in that growth stage. RELATED: Cannabis Cultivation Lighting Research Shows Shifts in Technology, Grower PracticesEaves said one of the best applications for LEDs is the vegetative stage, as LEDs don’t produce as much heat as traditional grow lights, giving cultivators the option to grow vertically. And there are large subsidies available in many U.S. states and Canadian provinces for those who use LED technology,…
