Here is serendipity: I knew Four Star Greenhouse from a small fungus gnat project many years ago. So I contacted the owner when I wanted to shoot some stock photos of the horticulture industry. I allied with a couple of friends and we shot video at the site, for Getty Images stock footage. Management was looking for an Integrated Pest Management Coordinator; I worked there for a year and a half.
Plants are grown on traditional benches (photo right) or on the floor in an ebb and flow system (photo left). My job was to evaluate scouting data and to walk through the crop to identify insect and disease issues. The idea of "integrated pest management" is to maintain pests/diseases below the economic threshold, by adjusting growing conditions (e.g., better ventilation = less fungal disease) and spraying when necessary. This is not a very "green" business. We used a lot pesticides.
The job I had at Four Star was valuable professionally but awesome from a relationship standpoint. People worked hard and smart, for little money. I had to ask them to wear cumbersome PPE and work with toxic materials late into the night.
