— Police dressed in protective suits found an estimated 200 mature marijuana plants and 100 seedling plants growing in an Edmond home Friday, calling it the largest grow house the department has seen.

Edmond police responded to a welfare check on a rented home in the 1300 block of Jamestown in the Copperfield housing addition after the owner could not reach the tenants, police spokeswoman Jennifer Monroe said.

The occupants, who were not at home when police arrived, apparently were getting their electricity from neighbors since at least mid-March, Monroe said. The electric company shut the house’s power off after suspecting the tenants were bypassing the meter boxes and pulling electricity from nearby homes.

The homeowner went to the house Friday morning to figure out what was happening and called police when nobody in the home responded to her, Monroe said.
