Precise tuning of light wavelength will be a key factor for success in the cannabis industry. Therefore, it is critical to understand how cannabis use and respond to light. In addition to the fundamentals, this presentation will provide practical information and calculations that growers can use to determine light use efficiency (LUE) and productivity as it relates to energy usage. Together, this information gives the grower an understanding of the physiological uses of light while also considering efficiency and the bottom line.
