Sostanza worked closely with our operations and management team, helping optimize our facilities, plan new projects, develop strategy, and train our team members. They supported planning and executing projects in Kelowna, BC and at our field site in Portugal. Juan, Philipp and Deron always make themselves available during production challenges and work closely with our team to solve problems. The nutrition program they implemented improved plant health and yield and lowered the cost of inputs, and they also helped with R&D projects, propagation, team structure, and cultivar selection. I wouldn’t hesitate to recommend Sostanza. They are highly professional, yet still very well-versed in cannabis culture and commercial production.
