Not an average greenhouse at NC State University

Published

on

It takes a minute to adjust your eyes to Joe Chierak and Mike Beddoe in hats through the greenhouse doors of NC State University’s Plant Sciences Building.

It’s so bright there’s a sunglasses case in the entryway.

“When the sun shines on the white floor, it’s like being blinded by snow,” says Beddoe.

But inside computer-controlled facilities, researchers work year-round to tackle the biggest challenges farmers face from disease, pests and extreme weather.

Plants for dozens of changing research projects are grown at any given time, all with different needs, requirements, growing seasons, and Chiera and Beddoe are tasked with overseeing them.

“We serve the entire campus,” says Chiera.

Increasing innovation

By editing specific genes in eucalyptus, NC State researchers like forestry professor Jack Wang and genome editing expert Rodolphe Barrangou are developing trees to make paper and other wood products, reducing emissions and promoting the sustainability of paper mills.

In another room, they set up chain-like runners of hanging strawberry plant racks, which can be used to root and grow more strawberries.

Associate Professor of Horticultural Sciences Mark Hoffmann is researching new ways to propagate strawberry plants to minimize the spread of pathogens before they are shipped from nurseries to growers.

Growing plants for this job requires precise control of light, humidity and other conditions.

Controlled environments for research accuracy

“This is the brains of the entire greenhouse,” Beddoe says, tapping into a control system that allows the researchers to adjust the environment in each room to their needs.

The facility includes 11 independently controlled greenhouse rooms spanning more than 10,000 square feet, as well as 25 plant growth chambers.

Sensors in each room continuously monitor temperature, soil moisture, CO2 concentration and more.

The data is then sent to a central computer, where it is analyzed and compared to optimal standards before issuing commands to the system, such as adjusting shade screens or turning on misters. Watering schedules are also programmed.

“We try to automate everything,” says Beddoe.

Safety first
Passing pots and earthenware, Chiera leads to one of the most unique rooms on the fifth floor.

The biocontainment greenhouse is one of the few facilities nationwide designed to safely screen for agricultural pests and pathogens.

Every year, farmers around the world lose up to 40% of their crops to pests and diseases.

As new threats continue to emerge that could threaten global food security, NC State is not taking any chances.

So they have converted one wing into a specialized high-capacity facility known as a biosafety level 3 laboratory.

Research here could be used to test treatments for crop diseases, for example, or to develop fruit and vegetables with greater resistance to insect pests.

The space itself is only accessible to credentialed staff, who work under the watchful eye of security cameras.

Chiera walks through the automatically closing doors and the researcher dons gowns, gloves, face shields and other protective gear before entering the lab.

What comes here, stays here
From air and water handling to waste disposal, it’s designed to ensure that what comes here stays here.

All water discharged from the BSL-3 greenhouse is run down pipes and boiled before leaving the facility.

Solid waste is treated in a special oven called an autoclave, which uses steam and pressure to ensure that any microbes are dead.

Air is also designed for safety.

A negative pressure ventilation system creates a flow of air in a direction to prevent anything in the air from escaping, and all the exhausted air is filtered out.

“So if we’re dealing with a pathogenic plant that produces spores, for example, it will trap them and not release them,” says Chiera.

Supporting diverse research in the face of tough challenges

In one room, tests are being done on the sweet potato. Electrical and Computer Engineering Professor Wenye Wang and his team are developing ways to help farmers monitor starchy and swollen roots as they grow underground, using low-cost Wi-Fi signals (PDF) instead of expensive buried sensors.

in another room, NC State Professor Dorith Rotenberg, Department of Entomology and Plant Pathology, is growing corn. Plants will eventually become dinner for insects, such as plant eaters and aphids, to better understand how these insects spread viruses that can stunt growth and reduce yield in one of the world’s largest crops.

A fan favorite
Beddoe stops in front of a room at the end of the corridor. “This is my favorite bay,” he says.

Inside, there are soybeans and banana plants basking in the sun, cotton plants with their hibiscus-like blooms, as well as a genetically engineered petunia that looks like an ordinary white flower during the day but glows at night using bioluminescent mushroom genes.

“These plants are mostly for our students,” explained Beddoe. “So they can learn different ways to water and breed and things like that.”

Always called
Beddoe will return here before heading home as part of his twice-daily inspections.

Because keeping the greenhouse running requires a lot of hands-on work.

“One of us is always on call,” says Beddoe, whose phone buzzes on evenings and weekends if something needs attention.

“Plants don’t take vacations,” he added.

“UK medical cannabis is maturing”

Published

on

By

The UK cannabis market has grown steadily over the past five years, although not always in the way operators had hoped. New brands and imported products have driven much of the expansion, while domestic cultivation has slowed. Alexander Mountain has seen this from the inside long before most people in the industry knew it existed. “I’ve been waiting for this since 2009,” says the founder of growing consultancy Trichome Solutions.

Regulations, compliance, EU-GMP requirements, all of which have made getting a facility off the ground a multi-year exercise. “I’ve worked with organizations and seen firsthand that it takes three, four, even five years to get going,” says Alexander. “It’s a tough market to break into in the UK, which in itself slows down the overall maturation.” The last six months, however, have brought about a change. “There are now clear goals and programs for business. An almost militant approach to protocols. It’s starting to feel like the rest of the EU and Canada.”

Capitalization and cultivation
Early investment in cannabis in the UK came largely from private capital, and the gap between capitalization and cultivation know-how cost many operators dearly. Consultants were brought in to design and build the facilities, but rarely stayed to operate them. The result was a facility that had to be rebuilt almost as soon as it opened. “A lot of adjustments, changes in workflows, logistical expansion,” says Alexander. “This, of course, requires more capital. This delays profitability and, in some cases, leads to employee burnout.” The model he believes in is the owner-operator structure that has worked in markets such as the US, Canada and Thailand.

In terms of cultivation, genetic selection and post-harvest are where Alexander gives most of his attention. Seasonal changes in the UK favor indoor parameters where possible, although low-light greenhouses have worked for some operators with adequate supplementary lighting. Getting the right genetics for the specific market drives early success and patient retention. Post-harvest, however, he believes the sector is constantly underestimating. “I focus a lot on preserving the plant material and maintaining its chemical profile, particularly cannabinoids, terpenes and volatile sulfur,” he says. “Even simple things, like having enough space to dry properly, seem like common sense. But unless you’ve actually done it, you don’t always realize how important those details are to the quality of the final product.”

UK cannabis demand
Patient demand in the UK has been shaped by the equity market, and licensed operators are working to close this gap. The dynamics here are different from other markets. In Germany and Canada, THC content drives purchasing decisions. In the UK, Alexander is seeing more focus on taste, aromas and the overall experience. “With the amount of choices coming in through imports, people are finding their own strains and becoming more selective,” he says. Closing this gap, in his opinion, involves the farmers as much as the prescribers. “Patient education and support should come from doctors. Producers should teach them about their products. I think growers should invite prescribers more often.”

Over the next three to five years, Alexander expects reliance on imports to ease as domestic supply chains develop and the market stabilizes. He says that there will be operators who come out from the other side, specialized ones. R&D, heritage genetics, premium indoor and post-harvest optimization. “We are now working in the international cannabis industry,” he says. “With comparisons, going on a flight, there is no room for complacency. The operators who find their niche and really excel in it will be the ones who build a strong identity and remain competitive in the cannabis space.”

DC Mayor Proposes To Let Medical Marijuana And Alcohol Companies Partner On THC Drinks

Published

on

By

The mayor of Washington DC is proposing medical marijuana companies partner with local breweries and distilleries to produce cannabis-infused and non-alcoholic beverages for sale in the nation’s capital.

Under the partnership envisioned by Mayor Muriel Bowser’s (D) Medical Cannabis Beverage Products Amendment Act of 2026, alcohol companies can apply for a medical cannabis production endorsement at a cost of $500 per year to manufacture cannabis beverages, and medical marijuana companies can apply for a $1,000 annual endorsement to import cannabinoids for production.

All beverages would have to be tested by a locally licensed laboratory, and there would be a six percent sales tax on beverages.

“This is an opportunity to support two local industries and keep businesses in DC,” Bowser said in a press release. “We have great local brewers and distillers in our city, we have a strong medical cannabis market, and this is a new opportunity for those two markets to collaborate and create a safe, smoke-free alternative for DC patients”

Breweries and distilleries would not be able to sell cannabis beverages directly to consumers, and the finished products would instead go to medical marijuana manufacturers for testing and distribution.

Sales would be limited to registered medical cannabis patients through dispensaries, and drinks could not be purchased at bars, restaurants, liquor stores and grocery stores.

“It makes sense for the District’s medical cannabis and alcohol manufacturing industries to collaborate to produce medicinal cannabis beverages,” said Fred Moosally, director of the Alcoholic Beverages and Cannabis Administration. he said. “Providing a legal way for our local breweries and distilleries to use their expertise in beverage production is the next step in reaching DC’s medical cannabis market and supporting our local business ecosystem.”

A press release from the mayor’s office said the proposal “works to solve the manufacturing challenges of the medical cannabis industry while providing additional revenue for DC’s local craft beverage producers.”

“Using the existing local bottling infrastructure, DC will expand smokeless therapeutic options for medical cannabis patients, provide additional revenue for the local industry and continue to grow the District’s economy,” he said.

The legislation is now before the District of Columbia Council for consideration.

Although Congress has consistently blocked DC’s legalization of recreational marijuana sales with a pilot approved each year, local officials have worked. expand access through the existing cannabis market for example, allowing residents and even visiting tourists to self-certify without the need for a medical recommendation.

We’re a small grow, which means we can control things very well

Published

At 5,000 square feet, Flora Arbor is about as small as a licensed cannabis grower can legally get. That’s not the problem the company is trying to solve. “We’re a very small breed, which means we can control things very well.” he says David Myrowitz, director of cultivation. “It also means that we have to be successful in every round.” Three flower cells, collected in three weeks. There is no such thing as a bad lot to disappear into a larger average. Every shift counts, and the operation is built around that reality.

It starts in the pump room
Reverse osmosis water is fed into holding tanks, nutrients are mixed by an Agrowtek fertigation machine, and the entire system runs from a GCX controller that monitors moisture sensors, dissolved solids, and soil temperature in every room. Canopy sensors feed directly into HVAC, which Flora Arbor runs on Cultiva units. “If you talk to any grower, any grower, they’ll tell you the number one thing for successful growing is having a good HVAC system,” says David. “There is somewhere that we don’t have expenses.”

Genetics and cells
Mother plants are removed every three to six months, so cuttings are always taken from young stock. The clones move from the humidity domes to a humidity-controlled room, then to the vegetables, where a crop-correction protocol runs several irrigation streams per day to encourage growth. Moisture sensors in the grow bags track each drying cycle, and daily watering patterns are revised based on the goals of the grow system.

The flower rooms have a double-level system, with taller plants at the bottom, shorter ones at the top, grouped to keep microclimates outside and an even distribution of light. The second mesh is lowered as the plants develop to give each bud site its own square and keep airflow moving through the canopy.

In a recent route, rooms from different phases of the cycle were working at the same time. Hawaiian Rain has been crossed with permanent marker, disk chips, cereal milk. David pointed to the development of crystals in the Hawaiian Rain cross, the citrus resin charge of Disco Fries, the height management challenge of pushing a cultivar as high as possible without burning them in the lights. “We try to have a nice spread of genetics, a nice representative of each flavor profile and effect, to make sure everyone can get something they like,” he says.

Crossing the finish line
Post-harvest is managed at home, by hand. The product is sorted on the cutting table A-Bd, B-Bud and cutting table, strictly separated, the grade on the label means something. The tiered structure also serves a second purpose. “We think it’s really important to make sure quality flowers are available to people of all means, not just people who can afford the premium,” says David. The three-week harvest cycle is Flora Arbor’s main argument for the consumer. Small batches, constant rotation, nothing stored.

“Every time you get a bag, it’s going to be fresh, freshly picked grass,” says David. “It’s not something that’s been sitting in some MSO’s vault for six months because they’ve collected 2,000 pounds and can’t sell it.” The bet is that in a market where no one has solved the consistency complaint, being small enough to catch all the cattle is more valuable than the economies of scale you allow to get there.
