The houses are typically outfitted with extensive hydroponic equipment to provide water, food, and light to the plants, and the houses themselves are usually kept in good condition to blend in with the neighbourhood. 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.{{cite web | url=http://realtytimes.com/rtpages/20020806_caneighborhoods.htm | publisher=Realty Times | work=Realty Times | title=Canadian Neighborhoods Threatened by Illegal "Grow Houses" | author=PJ Wade | access-date=2002-08-06 | archive-url=https://web.archive.org/web/20071220032648/http://realtytimes.com/rtpages/20020806_caneighborhoods.htm | archive-date=2007-12-20 | url-status=dead }}{{cite news | url=https://www.npr.org/templates/story/story.php?storyId=16628918 | publisher=National Public Radio | work=NPR News | title=Pot 'Grow Houses' Flourish in Pacific Northwest | author=Martin Kaste | access-date=2007-11-26}}{{cite web | url=http://www.dea.gov/pubs/states/newsrel/mia092006.html | publisher=Drug Enforcement Administration | work=DEA News Releases | title=35 Charged, 28 Arrested in Connection with Port St. Lucie Marijuana Grow Houses | access-date=2006-09-20 | archive-url=https://web.archive.org/web/20060923020710/http://www.dea.gov/pubs/states/newsrel/mia092006.html | archive-date=2006-09-23 | url-status=dead }}{{cite web | url=http://www.floridatoday.com/apps/pbcs.dll/article?AID=/20080319/NEWS01/803190331/1006/news01 | publisher=Florida Today | work=Florida Today | author=Susanne Cervenka | title=Titusville police bust grow house | access-date=2008-03-19}} {{Dead link|date=October 2010|bot=H3llBot}}
Law enforcement response
In the United Kingdom illegal cannabis growers usually bypass electric meter readers and "abstract" the electricity which is an offence in its own right. In the last ten years{{when|date=December 2022}} 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. Local media run regular stories advising local people on what to look out for including rarely visited properties with blacked out windows or with high levels of humidity on the inside. However, professional criminals are often able to defeat these efforts with the use of low-power lighting, activated charcoal filters, tube or inline fans, cooling systems and hydroponic systems.
In popular culture
In Tigerlily's Orchids, a 2010 novel by British crime-writer Ruth Rendell, a central plot theme is the operation of a grow house. A neighbour assumes his own house is so warm in winter because he has good insulation. However, his house is actually kept warm by the high heat from the grow house.{{Cite news|url=https://www.theglobeandmail.com/arts/books-and-media/tigerlilys-orchids-by-ruth-rendell/article561913/|title=Tigerlily's Orchids, by Ruth Rendell|newspaper=The Globe and Mail|date=13 January 2011|last1=Olson|first1=Sheree-Lee}}
