There are many successful grow operations in Denver and Aurora. The business models range from fully integrated companies to wholesale operations. Extraction and edibles (industrial kitchens) are big business too.
Investment property values are all about the zoning and separations requirements as defined by the local jurisdictions. Available power is also a major consideration. The vast majority of successful marijuana grow operations are in industrial warehouses in Denver and Aurora. 10,000 square feet warehouses with 1,200 amps are the most common, and most valuable operations. Although some of the major players have 80,000+ square foot operations, the current best practices opinions suggest a much smaller space for an efficient, and more controllable grow environment.
