Money is like any drug: first comes the high, then comes the crash. Last year, the iGrow hydroponics store in Oakland owned by Dhar Mann courted the media and Bay Area residents alike with the story of the “first out-of-the-closet marijuana hydroponics store.” Mann had big plans. His company started a college called UniCann. They launched a franchise WeGrow. But last week four small claims suits were filed against the Oakland company and its principles in what appears to be the first salvo in a series of legal actions this winter from a former partner, employees, and contractors.
