Director of Horticulture Science
Session Title: Lighting Strategy for Higher Yield, Better Quality and Reduction of Powdery Mildew
Time: April 3rd, 5:00 – 6:00 PM
Location: Seminar Room #2
Yan Ren-Butcher, Ph.D., is the Director of Horticulture Science at Illumitex. Her job is focused on providing Plant & Light educational trainings and scientific contents for marketing materials (such as white paper, grower guides, infographics), leading product trials, collaborating with research institutions and universities, as well as providing sales support to customers/growers. She also represents Illumitex as a member of the standard development committee of Electromagnetic Radiation Application for Plants of ASABE (American Society of Agricultural and Biological Engineers). After earning her Ph.D. degree in Horticulture Science from Texas A&M University, she started career as a Plant Scientist at Phillips Research. In addition to managing research projects with universities, she co-published the results of multiple studies in peer-reviewed journals. Later, she became a Product Manager at Hubbell Lighting to develop LED horticulture lighting products. Yan has many years of experience, focusing largely on helping to bridge the knowledge gap between lighting and horticulture to ensure her consumers understand the value of the lighting technology and find the right lighting solutions for their applications. She recently published white paper “Ultraviolet Supplement for Cannabis Production” and made a major contribution to Illumitex’s Cannabis Grower Guide as well as Vine Crop Grower Guide.

As a very high light plant, Cannabis growth and production is heavily influenced by its light environment. Although HID lamps were and probably is still currently prevalent in indoor/greenhouse Cannabis growth, for a decade, LED lighting technology has been rapidly developed for high light plants including Cannabis, and the technology continues to improve. When choosing a lighting solution for a Cannabis growth, several things need to be considered as a whole: light intensity, quality and uniformity.
Plants require a dynamic environment to optimize growth and development. Except light, the other environmental factors such as CO 2 , relative humidity, temperature, interact with light to impact photosynthesis and thus influence yield. Therefore, after switching to LED, the settings of these environmental variables also need to be updated accordingly to optimize your plant growths. This session aims to help you understand how lighting works together with the other environmental factors to maximize photosynthesis and how a tailored spectrum could possibly increase yield and quality (disease resistance, cannabinoids and terpene productions).
