I n the course of making a film about Britain’s cannabis industry, I have learned a lot about how to spot a cannabis farm. I have been schooled by policemen who raid them, gangsters who rob them and growers who set them up and produce more than 80% of the cannabis smoked in the UK today.

The latest Independent Drug Monitoring Unit report suggests there are now as many as half a million people growing cannabis in the UK, which equates to roughly one on every street. So how can you spot the cannabis farm next door to you?

Smell Follow your nose. A cannabis crop takes about three months to produce. During the final four weeks, the plants stink. Earlier this year, Crimestoppers helpfully issued cannabis-farm scratch-and-sniff cards to 210,000 homes in the UK to help you identify the exact bouquet.

Light Growers can’t get away from the fact that internal farming requires a lot of it: 2,000 watts running 12 hours a day in a small bedroom looks a lot like the sun, so look out for windows that are constantly blacked out to cover that up. Cannabis farms in spare rooms will have the tell-tale sign of curtains that never open.

Heat Those lights also give off a lot of heat, so the old theory was that the house growing cannabis in the loft would be the one with no snow on the roof in winter. But nowadays growers use internal tents, that isolate a lot of the heat. This makes farms harder for police to spot using their infra-red cameras.

Ventilation Growers need to ventilate the plants with large extractor fans, which generally emit a low hum. If every morning, at exactly the same time, it sounds as if someone next door is starting up their hovercraft, then it’s probably a cannabis farm warming up for the day.

Security Growers live in a paranoid world, always wondering when their door is going to get kicked in – not only by the police but by “enforcers”, violent criminals who make their living by stealing cannabis crops. For that reason many of them adopt Fort Knox-like security. Portcullises on the doors, bars on the windows and even CCTV cameras are not uncommon.

Activity Not all farms are inhabited by the grower so watch out for signs that there is no one actually living there: unkempt front gardens, or if your neighbour never leaves out any bin bags on collection day.

Good neighbourliness If the grower is in residence then it can go the opposite way. Perhaps the most surprising tell for having a grower next door might be their over-the-top neighbourliness as they overcompensate in their efforts not to annoy you or make you suspicious as to what they’re up to. As one grower told me: “I’m the nicest, most law-abiding citizen on my street, because the last thing I ever want is to give someone a reason to want to call the police to complain about me.”

But you may not be the only person trying to spot a cannabis farm on your street. The sinister side to these booming businesses is that they have become lucrative targets for harder and more violent criminals looking to rob them. These people are constantly on the look out for farms within our communities, which in turn exposes the rest of us to potential violence. What’s the solution? The dealers and criminals I spoke with all said that legalisation would put them out of business.

Roger Bertsch can’t stand the smell that wafts from his neighbor’s property. Sometimes it’s barely detectable in the afternoon breeze. But sometimes, he said, the skunky aroma is so penetrating he can’t keep the windows open, let alone enjoy a meal on his patio.

And because of the smell of his neighbor’s marijuana farm, the Spokane County Assessor’s Office recently took 10 percent off the value of Bertsch’s property on the outskirts of Cheney, the office of the Board of Equalization confirmed this week.

“Ever since they started growing cannabis, we’ve been getting a pretty intense skunk smell,” said Bertsch, who has lived in a house on West Washington Road with his wife for nearly a decade. Neither of them opposes marijuana on moral grounds – it just stinks, he said.

Their situation is one reason the Spokane County Commission voted unanimously on Nov. 29 to ban new outdoor pot farms – a move that drew the ire of local industry advocates. The ordinance is scheduled to last six months as the commissioners gather public feedback and consider making it permanent.

Commissioner Al French, who introduced the policy unexpectedly during a public meeting, said local officials have been “inundated” with complaints about smelly grow operations. He also sits on the board of directors of the Spokane Regional Clean Air Agency, which has fielded more than 200 such complaints since July 2014.

Bang’s Cannabis has been hit the hardest, with nearly 60 formal complaints from the Bertsches and other neighbors. The business also has been fined on at least two occasions for violating Clean Air Agency standards. Other pot grows have prompted few, if any, complaints.

Patrick and Lacey Bang, and their new business partner, Scott Kramer, insist they’re making good-faith efforts to mitigate odor. For example, they’ve installed several air purifiers in their greenhouses at a cost of more than $10,000.

“We’re not required to do it, but we’re doing it because we want to be good stewards,” said Kramer, an accountant who’s working to bring Bang’s into the black.

They also insist the smell is nonexistent beyond Bang’s property line.

“Everybody that comes here, we ask them, ‘Do you smell anything?’ And they always say no,” Kramer said. “Out at the street, you absolutely can’t smell it.”

That rang true when a reporter and photographer visited the farm on a brisk afternoon last week. Neighbors and Clean Air Agency officials say that’s part of the dilemma: The smell can be overpowering when a complaint is filed but vanish by the time an inspector arrives, making enforcement difficult.

“We are not a 24/7 agency, and odors can be very transient,” said Julie Oliver, the agency’s executive director.

The right place to grow pot?

Patrick Bang was a landscaper, and Lacey Bang worked for Providence Health and Services when voters approved Initiative 502 in 2012. Two years later, the couple was granted a license to grow recreational marijuana, and they set to work cultivating plants in their backyard.

Now they produce about 500 pounds per year. They say their plants are all organic, they reuse soil and other materials, and they plan to install windmills to power the grow lights.

“We’re a really sustainable brand, and I think a lot of people appreciate that,” Patrick Bang said.

Some neighbors would appreciate stricter zoning rules that keep pot farms out of residential areas, even rural ones where homes are farther apart.

“These things don’t belong anywhere near houses,” said Carl Caughran, who lives across from Bang’s on South Short Road. “I was there first for seven years. We try to get away from there now as much as we can. It’s just not enjoyable.”

Caughran and his wife have filed the majority of the complaints against Bang’s, but they insist they aren’t feuding. He said Patrick Bang “is not a bad neighbor, other than the smell.”

Kramer said Bang’s is in an appropriate location.

“One of our arguments is that we’re agriculture, and we’re in an agricultural zone,” he said. “It’s a crop. It’s a farm.”

Commissioner French has called the pot problem “a property rights issue.” He compared it to the stench that sometimes torments neighbors of the Baker Commodities rendering plant in east Spokane, where animal carcasses are processed into ingredients for cosmetics and pet food.

Flowering marijuana may reek less than simmering butcher scraps, but French said they both can infringe on a neighbor’s right to clean, odorless air. In 2003, when he was a Spokane City Council member, French pushed the city to sue Baker Commodities over odor violations, resulting in a settlement that officials said would mitigate the problem.

Tony Birch lives a half-mile north of Bang’s and said he still can’t escape the odor.

“In the summer, we have to keep the windows closed because the skunk smell just permeates the house,” he said.

Meanwhile, Laura Gardner lives just across the street from the farm and never catches more than a whiff.

“I don’t like it,” she said, “but it doesn’t bother me any.”

‘It’s not a toxic smell’

Some say the fragrance of unsmoked marijuana makes them nauseated, but Brian Smith, a spokesman for the state Liquor and Cannabis Board, said, “It’s not a toxic smell.”

The board handles permitting and ensures pot farms are up to code, but no state agency responds to odor complaints. Instead, they are forwarded to local entities such as the Clean Air Agency.

“It really is a patchwork across the state,” Smith said.

Julie Oliver, the Clean Air Agency director, said, “Under state law, odors are considered air contaminants.”

But some say the agency shouldn’t bother with marijuana producers.

“I would prefer that the Clean Air Agency would be spending their time with pollutants that cause global warming, and not worrying about how to stifle a new industry,” City Council President Ben Stuckart said last month.

This year, the agency organized a Marijuana Advisory Committee, but the agency doesn’t target pot farms. Oliver said inspectors also respond to complaints about more traditional farm odors, such as manure.

The county’s moratorium does not affect existing farms or those with pending applications. Currently, 39 producers in the county operate at least partly outdoors, according to Liquor and Cannabis Board data. Greenhouses without rigid walls don’t count as indoor facilities.

Patrick Bang believes his farm has been unfairly targeted and said the county commissioners likely received “bad information.”

“To hinder all the outdoor grows that don’t have any issues seems very unfair,” he said. “I think if you had any of the commissioners come out here and walk the property line, they might think differently about the problem they’ve got here.”
