- Windows are sealed and covered or the curtains are permanently closed

“Officers have today discovered a substantial cannabis cultivation in a house which is solely being used for this purpose.
We would take this opportunity to appeal to the public to continue to report suspicious activity or information to stop those involved in the drugs trade."
Lancashire Police have discovered a "substantial" number of cannabis plants at a house in Ormskirk.
Police forces across our region have launched a crackdown on those who grow and sell the drug. They warn that the last few years have seen a big increase in small so-called cannabis farms springing up in our region - many run from rented properties in the heart of otherwise respectable areas.
In the last three years, police have found:
- 5,120 cannabis factories in the North West
- 345,000 cannabis plants.
- All that has a street value of £140 million
A huge crackdown on people growing cannabis has been launched across the North West.

It's not just happening in and confined to industrial units. It's happening in our communities, it's in peoples bedrooms and lofts. The result of that is its actually bringing that gun crime element into the heart of our communities.
