Lytton RCMP found 742 marijuana plants on crown land near Goldpan Provincial Park south of Spences Bridge.
The grow op was dismantled Saturday but no charges have been laid, Cpl. Dan Moskaluk said.
The discovery came one week after Lytton RCMP raided a home in the 3000 block of Riverview Avenue in Spences Bridge.
Officers seized 158 plants and 15 pounds of processed and packaged marijuana.
A 45-year-old Spences Bridge man faces a charge of production and possession for the purpose of trafficking.
