By the time his cannabis plants begin to flower later this year, Jon Piasecki plans to have in place a system that will spare his neighbors — at least mostly — from the powerful stench many endured last fall.

Piasecki, co-owner and proprietor of Wiseacre Farm, this week unveiled a $250,000 eight-point "odor mitigation" action plan, starting by regrading a hill to create a bowl with trees and a 75-foot wall to help block odors.

At Monday night's hybrid Select Board meeting, he acknowledged the smell of the flowering cannabis plants was stronger than anticipated when he initially came before the board for approval last year.

"We didn't know the intensity it would be [during the first cultivation season]," he told the Select Board members. "There is a problem. I get it; cannabis smells bad, [people] don't like it."
