WORCESTER – It was weekend heaven for cannabis enthusiasts at the DCU Center with pot product lines on display, ganja competitions and a nearly 120-foot joint wrapped in gold.

The Mass. Grower Advocacy Council, MassCann/NORML and the Mass. Patient Advocacy Alliance hosted the second annual Harvest Cup that was attended by thousands. Cannabis aficionados gathered at the two-day event to show off some of the best locally-sourced ganja and edibles, and to roll a world-record long joint.

Cannabis Control Commission Chairman Steven Hoffman delivered the keynote address at the 21-and-over event.

And all one had to do to find the event was follow their nose to more than 200 pot vendors from across the nation.

Caroline E. Frankel, owner of women-operated Caroline’s Cannabis opening soon in Uxbridge, and manager Molly A. Phillips, said it was their first year participating in the herb extravaganza.

Ms. Frankel, a 17-year cannabis enthusiast, said she is a graduate of the Northeastern Institute of Cannabis and attended Johnson & Wales University for business. She holds a provisional license to sell retail, and will offer flowers, concentrates, wooden signs and other products at her cannabis boutique.

“We want to spread the kind word of cannabis,” Ms. Frankel said. “That’s what it’s all about this weekend.”

Scott H. Brodsky, director of sales and marketing for The Harvest Cup that coordinated the event, said organizers want to grow the cannabis competition, trade show and expo each year.

“We have vendors from all across the industry,” Mr. Brodsky said. “We believe small and medium businesses are the lifeblood of the industry – the ‘mom-and-pop’ shops. That’s who we are and that’s who we believe will really make this industry flourish.”

There were 12 categories for a 60-judge weed competition, he said, including indoor and outdoor flowers, sweets and savory edibles, tinctures, syrups and sauces, and vape pens.

“The winner gets to take all the other competitors’ entries to do what they want with,” he explained. “That’s our motto: smoke the competition.”

Beantown-Greentown of Boston organized rolling the nearly 120-foot joint. They are planning to hold a smoking event on April 20, he said, at the private club, Summit Lounge, in Worcester – the only pot consumption club in Massachusetts.

“I wouldn’t miss it,” Mr. Brodsky said. “They plan to smoke a foot an hour for 24 hours.”

Steven J. Goldman, COO of QIC in Weymouth, partnering with GS Thermal Solutions, demonstrated spectral controls on a lighting system used to grow indoor pot plants. QIC was launching the brand at the event, their first trade show.

“You can change the parameters across four different light spectrums for different stages in plant development,” Mr. Goldman said. “It’s incredible. There are strict regulations on what you can feed the plants and … It is absolutely imperative to have a clean indoor grow and you can do it with this system with little trouble.”

Calvin N. Edith, manager of Headdies of Pennsylvania, demonstrated for Don Gill of Rhode Island how to use a 3-D printed nectar collector.

“I came last year for the VIP party,” Mr. Gill said. “On a scale of 1-to 10 it was a 10. This year is awesome still. It is much bigger and there is so much variety.”

Cecilia L. Howard of Brookline, N.Y., attending for the first time with one of the vendors, checked out the long joint.

“I love it,” Ms. Howard said of the event. “Everybody is so nice. It’s awesome and really cool.”

Matt D. Bergen, 25, known as “Coach” of Coach Bergen of Westfield, smiled as he held up a foot-long joint he rolled wrapped in gold.

“They taught me how to roll and we live-streamed it through Instagram,” Mr. Bergen said. “I learned how to roll today. As soon as I get out of here I am going to smoke it. I was scared of weed when I was younger. Now, weed is all I need.”

Rich P. Cahoon from Beantown-Greentown, said the group believes they broke a world record last year with their 106-foot joint, but Guinness Records were not accepting the entry because cannabis is still against federal law.

“This year, we rolled one 119½ feet long,” Mr. Cahoon said. “I would have gone to 120 feet, but I ran out of table.”

He said the event is a great way to connect with others in the industry and pot enthusiasts once a year in the area.

“We have similar events in Boston to come together to enjoy the fruits of our labor, so to speak” Mr. Cahoon said. “Worcester is very accommodating. There are plenty of nice people and parking and you have the only consumption lounge in the state.”
