Design Partner and Crop Advisor of Whipple Effect, Partner and Co-Author of The CCI Book
Marielle Taft has been working in the horticulture and root zone management field since her time at UC Berkeley where she studied and researched crop physiology and soil microbial ecology. Focusing on the rhizosphere’s impact on crop development, Marielle’s expertise spans soil, soilless, and hydroponic cultural methods. Marielle entered the Cannabis industry ten years ago and has extensive experience in multiple areas of commercial production including cultivation facility management, large-scale CEA design/build (indoor and greenhouse), integrative pest management, irrigation and fertigation design, and water quality management. Her background in soil and IPM laboratory and field research coupled with her passion for data-driven cultivation has brought her all over North America to consult with controlled environment agriculture operators seeking to produce the highest quality Cannabis with unrivaled efficiency and sustainability. Prior to crop consulting at Grodan, Marielle acted as the director of cultivation for licensed indoor and greenhouse operations in multiple states. Internally, within Grodan, Marielle works with the technical teams to design and assist substrate trials at Wageningen University focused on precision irrigation and crop steering strategies. She is an international speaker delivering seminars on precision irrigation, crop steering, and data-driven growing strategies to a broad array of Cannabis stakeholders and industry leaders. As a technical crop advisor for Grodan North America she provides horticultural and operational insight to growers and MSOs all around the United States while spreading her passion for precision irrigation and root-zone management. In recent years Marielle’s enthusiasm for closed-loop water systems and her dedication to water conservation has brought her in close contact with the Resource Innovation Institute where she continues to foster her core values of efficiency and sustainability in CEA production, helping producers grow more with less each and every day.
