A 42 year old Kelowna man is facing a drug charge, even though he had a licence to grow.

Police investigating a possible grow-op Wednesday  in an apartment on the 2200 block of Benvoulin Road found about 170 plants and a half-pound of bud.

"After further investigation it was revealed that the tenant, a 42-year-old Kelowna man, had a medical marihuana licence, but not for the apartment," says Kelowna RCMP Const. Kris Clark.

"Not only was the licence for a different address but he had only been approved for just over half of the amount that was found growing."

No one was inside the residence at the time and no charges have been laid, but the investigation is ongoing.

The man faces potential charges related to production of a controlled substance.
