Marijuana growing is not a green industry.
Done mostly indoors in Washington, pot production often uses hospital-intensity lamps, air conditioning, dehumidifiers, fans and carbon-dioxide generators to stimulate plants and boost their potency.
The power-hungry crops rival data centers and server farms in their intense use of electricity, according to a peer-reviewed study last year in the journal Energy Policy. One kilo, or 2.2 pounds, of pot grown indoors, the study says, leaves a carbon footprint equivalent to driving across the country seven times. Producing one joint is equivalent to leaving a light bulb on for 25 hours.
There’s little question that sun-grown pot is a cleaner alternative, even in Washington, which uses mostly hydropower, considered greener than most energy sources.
“It’s great we have relatively low-carbon electricity, but that’s not a license to waste it,” said KC Golden, policy director for Climate Solutions, a Northwest nonprofit working against global warming.
It doesn’t make sense to move agriculture indoors, Golden said, given the sun’s track record of “encouraging photosynthesis for some 4 billion years now, without an outage.”
But in this blue-green state, very few folks are lobbying for pot grown under the sun in Eastern Washington, where the climate is suitable, in part because of security concerns about outdoor grows. And absent a stronger push, it appears that state-regulated retail stores will open next year without sun-grown weed on their shelves.
Golden said he hasn’t studied the issue, particularly the implications of outdoor pot for law enforcement. Leaders at other environmental groups such as the Sierra Club and Conservation Northwest say they have other priorities. Even in Seattle, where the City Council is writing new zoning rules allowing large indoor grows, no one seems very concerned with the carbon footprint of indoor pot.
Instead, the chief advocates for outdoor pot in the state are Okanogan County activist Jeremy Moberg and state Rep. Joel Kretz, a Republican from Wauconda. They say outdoor pot should be grown in greenhouses that allow in natural sunlight, not expansive open fields.
“The waste of our clean hydropower, wind and solar electricity for a nonfood crop used primarily for recreation is simply unacceptable,” Kretz, a rancher, wrote the state Liquor Control Board, the agency charged with carrying out voter-approved Initiative 502. Sun-grown pot could also be an economic boon for his rural constituents, Kretz noted.
And it probably would be cheaper than indoor weed, Moberg said, helping the state achieve its goal of undercutting the black market.
Weed politics
The politics of producing pot are complicated, however, by the federal prohibition of marijuana looming over the state, and a state timeline for opening retail stores that seems to give the entrenched indoor industry a running start in competition with outdoor cultivators.
Gov. Jay Inslee won’t comment on pot growing, according to spokesman David Postman, even though the governor recently declared Washingtonians “are the people who are destined to defeat carbon pollution.” He doesn’t want to micromanage the Liquor Control Board, Postman said.
Inslee did address the subject on a radio show earlier this year. He said he assured U.S. Attorney General Eric Holder that Washington will keep its weed from leaking into other states, and there may be security reasons for keeping pot production under lights, behind locked warehouse doors.
Some at the liquor board question how the energy study, based on California research, translates to Washington. State pot consultant Mark Kleiman co-wrote a book that claimed the study overstated pot consumption.
Still, the board seems somewhat receptive to sun-grown weed.
Sharon Foster, the board’s chairwoman, recently said the state would license indoor and greenhouse growing, though not open-field production. Chris Marr, a board member from Eastern Washington, agreed the state agency is leaning in that direction, though no decisions have been made.
Outdoor growing can be made secure with razor-wire fences, surveillance cameras and other measures, according to Dan Williams, president of Canna Security America, a firm based in Colorado where outdoor cultivation is allowed. “It’s absolutely doable,” Williams said.
California pot activist Steve DeAngelo emphasizes that just an acre of weed can yield enough to sustain a family farm.
“People who care about our environment, who respect Mother Nature, need to make this a priority and demand that rule-makers and regulators allow cannabis to be grown like every other crop in the country,” said DeAngelo, while in Seattle recently for a meeting of investors hearing pitches from marijuana entrepreneurs, including Williams.
Undercover grows
The director of California’s largest dispensary, DeAngelo said the best pot he’s ever seen came from northern California outdoor grows in the 1970s. But federal flyovers and crackdowns on outdoor plants in the 1980s pushed many growers indoors.
By bombarding plants with light and nutrients, indoor growers were able to produce higher-potency weed, said Scott Zeramby, technical consultant on the carbon-footprint study by scientist Evan Mills.
A generation or two of consumers have grown up with the misperception, DeAngelo said, that sun-grown is inferior.
As with grapes, outdoor pot can exhibit traits of the environment it’s grown in — what wine aficionados call “terroir.”
“Think about it,” DeAngelo said. “Do you want to eat tomatoes grown in a hydroponic solution under high-intensity lamps, or do you want tomatoes grown organically under the sun?”
No one knows how much weed is now grown in Washington, not to mention where and how. But state officials have roughly estimated annual consumption at 186,000 pounds.
According to the carbon-footprint study, the energy used to produce one joint would produce 18 pints of beer. That means growing the state’s supply indoors for a year would require the same energy as producing 3 billion pints of beer.
No one was making that case in Washington, though, until Moberg of the Okanogan Cannabis Association started agitating a few months ago.
A wildlife biologist by profession, Moberg, 38, grows for medical patients in a greenhouse with fabric roof and walls.
Washington’s northern latitude doesn’t allow the kind of unfettered outdoor gardens that thrive in California, he explains. He augments his growing with lights early in the plants’ lives — although he figures he uses only 1.4 percent of the electricity that an all-indoor operation requires. In the hottest days of summer, he peels back the greenhouse roof and walls to cool plants.
When Moberg made a pitch to the Liquor Control Board, replete with PowerPoint photos of large greenhouses in the Netherlands, Marr said state officials had an “aha” moment realizing that sun-grown did not necessarily mean open fields of pot next to amber waves of grain.
Granted, Moberg has an interest in outdoor growing, but he and others see the security argument as a red herring. “That’s the fear-based argument the feds like to talk about to have some control of this,” said Zeramby, the study consultant.
Moberg acknowledges that illegal outdoor growers in California have damaged the environment by diverting water from salmon-spawning creeks, deforesting areas and eroding hillsides. But legal growing, in theory, would adhere to strict rules and avoid such problems.
And stored under the right conditions, Moberg said, sun-grown weed could last through a year, for a sustainable supply.
Green marijuana
The state’s new regulated seed-to-store system aims to cripple the black market. Prices are key to that goal. Moberg believes greenhouse production could be considerably less expensive than indoor growing, even with Washington’s relatively inexpensive electricity.
Despite all the apparent arguments in his favor, Moberg wasn’t able to find allies in the environmental movement.
He turned to Kretz, a lawmaker with a contrarian streak. During a recent debate about wolves, Kretz sponsored a bill that would move wild wolves to the west side of the Cascades. He figured west-side lawmakers loved wolves so much they should have some in their own backyards.
Moberg wrote Kretz a letter saying sun-grown pot was an issue where the socio-economic and environmental arguments favored the east side.
Kretz jumped on it. “I want green marijuana,” he said in an interview. “The land here is cheap, we have good soils and lots of sun.” Not to mention unemployment of 15 percent in Ferry County, which he represents.
Now that recreational pot is legal, he said his attitude is “let’s make the best of the situation, whether you agree or not” with its use.
December licenses
The state liquor board expects to release draft rules next month.
While board members are leaning toward allowing greenhouses, key details such as the number of licenses, the size of operations and how they might be dispersed geographically all remain to be determined.
Right now, the board’s timeline calls for issuing licenses in December. With the four months required for growing and curing, that would allow stores to open next spring.
That schedule would seemingly put sun-grown weed at a competitive disadvantage, playing catch-up. Moberg said he could have his harvest ready by July Fourth. He’d like to see the licensing schedule pushed back several months to give outdoor growers a chance to supply retail stores when they open.
“My hope is they’ll get settled on security issues and at least put some solar people in the mix,” Kretz said of the board’s rule-making.
