D'IBERVILLE, Miss.--A marijuana grow house has been busted in a D'Iberville neighborhood and narcotics agents say it was a sophisticated operation. About 200 pot plants were taken by the Coastal Narcotics Enforcement Team shortly before 9 Thursday night.   Also inside the home, which was in an all-residential neighborhood, according to WLOX, were lights and computers and all the chemicals used to properly grow that type of garden. Agents told media this is the ninth such operation busted since October. They had backed a trailer up to the house and were still working on getting all of the pot and equipment out of the house early Friday.
