How does your cannabis grow?
From our UK edition
Pot plants A 65-year-old Devon woman rang a BBC gardening show to enquire about a mystery plant only to be told it was a cannabis plant. Some other places cannabis plants have been found: — In 2012/13 British Transport Police found 500 plants growing across the rail network, including one at Hounslow station. — Under lights in the boiler room of a Streatham primary school, which was alerted by an electricity company concerned at excessive power consumption. — Outside the Tower of London, apparently planted by pro-drugs activists. Police decided that the campaigners had committed no crime because they had only scattered seeds, not cultivated the plants. — At Kew Gardens, which has an exhibition this autumn featuring illegal plants.
