Grow house

A grow house is a property, usually located in a suburban residential neighbourhood, that is primarily used for the black market production of marijuana, it may be used for the cultivation of other drugs such as psilocybin mushrooms.

Illegal electrical hookups are a common feature of grow houses, to both save money and to make it harder for authorities to identify them due to their unusually high electrical usage.

authorities in both the United Kingdom and the United States of America have become more aware of grow houses and have introduced policies focusing law enforcement, local government authorities, energy providers and landlords on disruption and detection of illegal grow houses.

In the United Kingdom the Proceeds of Crime Bill targets criminal profits and unevidenced sources of income from convicted drug producers.

In Tigerlily's Orchids, a 2010 novel by British crime-writer Ruth Rendell, a central plot theme is the operation of a grow house.
