Blue Mau Mau:  “Franchising has now officially gone to pot. A marijuana hydroponics franchisor, weGrow, opened its first franchise Wednesday. It anticipates its new 21,000 square foot medical cannabis franchise will sell products to an estimated 100,000 medical marijuana growers who reside in the Phoenix area.  ‘We’re not talking tomatoes,’ whimsically says Arizona’s first weGrow franchisee Sunny Singh.   The superstore is weGrow’s third. It has two California stores: one store in Oakland opened its doors in January of 2010 and the Sacramento location launched in February of this year. While not selling pot itself, the franchise aims to be a one-stop shop for cannabis cultivators.”
