 Hey, it's been a year since Maryland legalized recreational weed. Since then, the industry has generated tens of millions of dollars in tax revenue for the state. WTOP's Nick Ionelli dropped by one of Maryland's facilities for an exclusive look at how weed is produced in large quantities. You'll notice it's warmer and more humid in here. There are so many moving parts to this cultivation facility in Timonium. It consists of multiple huge warehouses with rows and rows of marijuana plants, each plant guided through its entire life cycle.
