JR Loza
US Consulting Lead, Commercial Cultivation
Over twenty years running large-scale commercial cultivation in California. JR is a pioneer in high-quality production at scale and one of the most experienced operators in the industry.
Quality and quantity.
No compromise.
JR has been running large commercial cultivation facilities in California since the early 2000s. He is one of the industry's earliest pioneers in producing consistently high-quality cannabis at commercial scale, long before the current generation of licensed operations existed.
His approach draws on Israeli agronomy principles and large-scale controlled environment agriculture, adapted to the specific demands of cannabis production. JR's cultivation philosophy centers on Total Crop Steering: precision control over every input to maximize both quality and yield without sacrificing either.
As Grownetics' US consulting lead, JR brings this operational depth to facility design, system selection, SOP development, and team training. He has helped turn around underperforming facilities for major brands across California, delivering measurable improvements in consistency, throughput, and product quality.
