GTI’s Marijuana-cultivation Facility in Holyoke Is a Budding Enterprise

Growth Industry

Matt Yee stands outside a room equipped to simulate ‘summer.’ Access inside is extremely limited.

Green Thumb Industries’ marijuana-cultivation facility in Holyoke is not like most other businesses — or any other business, for that matter. There is no sign over the door, there was no elaborate ribbon-cutting ceremony when it opened, and, with a few minor exceptions, no one will visit this place. It is like all other businesses, though, in keeping the focus on innovation and putting out a quality product.

The ‘flowering room,’ as it’s called, is climate-controlled to simulate early fall.

And it does that so well that when Matt Yee, president of the Massachusetts market for Green Thumb Industries (GTI), walks inside … he has flashbacks of a sort.

“This is perpetual September. I always feel like I’m walking through the Holyoke Community College parking lot at the beginning of school — it always reminds me of that.”

“This is perpetual September,” he told BusinessWest, referencing the temperature, the warmth of the sun, and a slight, cool breeze. “I always feel like I’m walking through the Holyoke Community College parking lot at the beginning of school — it always reminds me of that.”

Perpetual September? Welcome to GTI’s 45,000-square-foot marijuana-cultivation facility in Holyoke, a recently opened venture that is, in just about every way you can imagine, not like any other business in this region.

That much becomes abundantly clear after one short visit — only, you really shouldn’t expect to visit this place anytime soon. They don’t exactly roll out the welcome mat — not because they’re not friendly, but because they don’t want or need company.

For starters, there’s no signage on the property, at least for GTI (there are other tenants in this old paper mill), and for a reason. The company doesn’t exactly want to broadcast its location, although its address, 28 Appleton St., in the so-called Flats section of the city, is commonly known.

Also, there is no front door, really. You enter through the back, and only after using a coded key to get through a tall gate and passing under several surveillance cameras. Once inside — again, if you get that far — you can’t go any further without checking in with security, leaving a copy of your driver’s license behind, getting a badge with a recorded number on it, and being escorted by an employee through some more locked doors.

But before going through — and unless you’re an employee, an elected official on business, some other sort of VIP, or a business writer on assignment, you probably won’t be going through — one must step onto a large mat of sorts covered by about an inch of water.

That’s because marijuana plants are somewhat fragile and susceptible to contamination that might be brought into their home on the soles of one’s shoes. For the same reason, no one gets further than the security desk without donning a white lab coat.

“Contamination of the system can cause millions of dollars in damage,” said Yee. “Even walking across the parking lot, people can pick up some powdery mildew — one of the biggest issues we have — or various aphids and bugs, and those can be issues as well.”

To help keep these plants — which give new meaning to the phrase ‘cash crop’ — safe, GTI has enlisted the help of what are known as “beneficials” — tiny mites that feast on many of the known enemies of marijuana plants. There are hundreds of them in small packets placed next to each plant.

“If there’s an invasion of aggressive bugs, they’ll eat those little guys,” Yee said of the mites. “It’s an interesting process — signing the invoice for 25,000 bugs was kind of interesting; they’re very, very, very small, but you can see them, although it’s like looking for a needle in a haystack.”

These are just some of the steps (ladybugs and other beneficials are also deployed) being taken to ensure that the first crop, and all those to follow — the business plan calls for cultivating 120 pounds per month — will be as healthy and profitable as possible, said Yee, who came to this job and this industry thanks to a chance encounter with Pete Kadens, president of Chicago-based GTI at the restaurant Yee was managing (more on that later).

The flowering room he showed BusinessWest was empty, but by the time this magazine went to the printer, it was full of plants enjoying those cool fall breezes. From there, it’s only a few more steps until the fruit of the plant is processed into product, such as the small joints called ‘dog walkers’ — because you can start and finish one in about the time it takes to walk the dog — to be placed in tins already stored in the so-called trim room.

“It’s a great little product — everybody really loves these all across the nation,” he said, adding that, starting in several weeks, these dog walkers and other products will be shipped to GTI’s recently opened dispensary in Amherst and other locations across the state.

For this issue, BusinessWest takes an in-depth look inside GTI’s facility in Holyoke, and also inside a business that is new to Massachusetts and this region, but appears to have a future that might be as bright as the high-pressure sodium lights inside the flowering room.

Branch Office

Those are 1,000-watt units, and there are 88 of them in the room, Yee explained, adding quickly that it gets so bright in those rooms that employees wear protective sunglasses when inside.

That was one of many bits of information Yee passed along while serving as tour guide, one of many functions he’s taken on (although, now that growing has started, the volume of tours has subsided) while carrying out a role he probably couldn’t have imagined for himself a few years ago.

But the picture changed quickly and profoundly after Kadens ventured into Johnny’s Tavern in South Hadley for dinner back in 2016. Yee, as noted, was general manager of that eatery (one of many owned and operated by his family), with the emphasis on was. Indeed, the two started talking, and the more Kadens talked about the cannabis industry and its potential in the Bay State, the more Yee wanted to be part of it.

To make a long story somewhat shorter, Yee joined GTI and has taken a lead role in opening the Holyoke facility and getting the first plants in the ground, if you will.

First, though, there was a lengthy learning curve for Yee, who said his education in cannabis and the business of cultivating and distributing marijuana took him to GTI facilities across the country, including those in Colorado, Nevada, Illinois, and Virginia.

“It was a really intense drop into the cannabis world,” he recalled, adding that GTI has facilities similar to the one in Holyoke operating in several states.

The operation on Appleton actually represents what Yee called the third iteration of a GTI growth facility. Lessons have been learned over the years, he said, in everything from production to automated systems to air handling, and they’ve all been applied to the Holyoke plant, which came to be after a lengthy review of options regarding what to build and where.

“It came down to ‘should we do this in an open field somewhere for cheaper or do the socially responsible thing and breathe new life into a vacant space?’ And we decided to do this — and it was a project.”

Indeed, as Yee walked through the facility, he noted that, while it provided one key ingredient in the form of wide-open spaces and high ceilings, the old mill required quite a bit of expensive work to be retrofitted into a marijuana-cultivation facility.

But in the end, GTI determined that rehabbing such a facility is a better alternative to building new, even it is the more expensive alternative.

“It came down to ‘should we do this in an open field somewhere for cheaper or do the socially responsible thing and breathe new life into a vacant space?’” he recalled of the decision-making process. “And we decided to do this — and it was a project.”

‘This’ was a retrofit in the middle of an urban setting, granted one that has embraced the cannabis industry with open arms.

Thus, security is extremely tight, he said, noting the facility is outfitted with cameras, motion detectors, glass-break sensors, and more.

“Visitation is very, very restricted,” he said, adding that the state has access to the facility’s camera systems and monitors what goes on. If someone watching sees someone in the building without a badge, inquiries are made.

Joint Venture

Yee’s ability to learn quickly about the industry he joined was in evidence on the tour, as he talked about marijuana and, more specifically, how it will be cultivated in this old mill.

“Marijuana is an annual,” said Yee, who walked while he talked. “Typically, the seeds will pop in the spring, it will grow through the summer, and then, come the shorter days of late summer and fall, its flowering process is triggered — and it’s those flowers that we’re harvesting; it’s the fruit of the plant.”

Matt Yee says it will be a few more months before GTI is able to fill tins of ‘dog walkers’ it will ship out the doors of the Holyoke plant.

There are no seasons, per se, indoors, so cultivators like GTI have to replicate them, he went on, as he stopped at a room simulating early- to mid-summer. Through a large, thick window, Yee pointed to and talked about the already-tall plants inside.

Taking visitors in that room, even after they’ve put on a lab coat and stepped on a few of those water-covered mats, constitutes far more risk than the company is willing to take on, he said, adding that these plants are much too valuable to risk contamination.

The sign on the door gets this point across. “Do Not Enter — Limited Access Area,” it reads. “Access Limited to Authorized Personnel Only.”

“There are about 18 hours of light in this room,” said Yee, returning to the subject at hand and the process of simulating summer-like conditions. “We’re really just pushing the plants to get to a proper size, and then we stimulate them to get to their flowering stage.”

Actually, the ‘summer’ room is the second stop for the plants, which start off as cuttings from other plants, known as ‘mothers,’ and take up residency in the ‘cloning room.’

Their third stop will be in that room that simulates September, where it is a constant 72 degrees, Yee went on, adding that the first plants were due to arrive there in early June.

In that setting, a shorter day, with the lights on for maybe 12 hours, is created. That difference in the amount of light is what actually triggers the plant to move into its reproductive cycle, he explained.

“The male plants will develop pollinating elements, and the female plants develop the flowers,” he noted. “We only have females here; there are no males on site.”

The plants will double or triple in size in the flowering room, he went on, adding that, when they’re ready for harvesting, they’re removed from their pots, the iconic fan leaves are removed, and the flowers are put into a drying room, to be hung on what are known as ‘Z racks.’

Once the flowers reach a certain level of dryness, they can be processed, said Yee, adding that the product is weighed and then moved into the ‘trim room,’ a space where the flowers are “manicured” (Yee’s word) into their final, saleable form, such as those aforementioned dog walkers.

From beginning to end — from the nursery to that tin of dog walkers — the process covers about three months, and, starting with the second batch, there will be continuous yield at this facility, which will be needed to recover the significant investment (nearly $10 million) in this facility.

“We’ll be harvesting about half a room a day,” he projected, adding, again, that the overriding goal is to keep the crops safe — from invading insects and anything else — until they’re harvested.

Yield Signs

Getting back to those packets of beneficials, Yee said the mites are really small and quite hard to see, and he’s essentially taking the distributor’s word that there were 25,000 of them in that last order.

“If you crack one of the packets open and pour the contents in your hand, there’s sawdust or whatever it is … and if you look hard, you can spot these little critters rolling around.”

What’s somewhat easier to see is the vast potential for the cannabis industry in Massachusetts, although that picture is still coming into focus, on both the medicinal and recreational sides of the spectrum.

GTI intends to be well-positioned to capitalize on whatever market eventually develops, and the Holyoke facility will play a huge role in those efforts.

It is really unlike any business you’ve ever visited — only, you won’t know, because you probably won’t be visiting.
