I had the pleasure of working with Drew on a cannabis cultivation project in Missouri. His knowledge and expertise with growing and the importance of temperature and humidity and its affect on plant health and yield was impressive. His insights were invaluable to the success of the project, and I learned a great deal from his experience. I look forward to working on future projects with Drew.

We have worked with Drew for many years. His ability to diagnose and to control environments under any circumstance has been spectacular. He leads from the front and would never ask anything from his team members that he isn’t willing to do himself. “He’s a top pick in any draft.”

I first met Drew Greco on a project in Massachusetts in 2019. AGS provided the climate control system for a 40,000 square foot facility and Drew was a grower there. Out of the entire staff he was by far the most engaging and inquisitive member. I came to know him as the person who had the most complete and holistic knowledge of the facility’s operation. He understood the horticultural facet of the grow but also made it his business to understand the mechanics of the facility itself, it’s controls, scheduling, maintenance SOP’s, everything there was to know. I have been in this business for a long time and it’s exceedingly rare to find an individual who understands the workings of a cultivation facility so assiduously. His knowledge and energy are critical to the success of any cultivation project.
