Virginie Boivin enters the room out of breath. One of her employees let her know over the walkie-talkie that we were there. A firm handshake, a smile emerging despite the stress we can sense. Mushrooms may be known for their exponential growth, but the energy Virginie exudes as she welcomes us is equally impressive.
“I’ve been growing mushrooms for 10 years. I started in 2018 in a tiny space of about 50 square metres. Today, we have ten times that amount of space across our new production and food-processing areas and the laboratory. Big Bloc is a bit like a three-headed dog: we produce fresh mushrooms for distributors, restaurants and individuals; process food, including preserves, spices and dried mushrooms; and run a laboratory where we produce mushroom cultures and substrate blocks for other farms that may not have the necessary equipment. We produce around 400 to 500 blocks and 300 kg of mushrooms per week, including Lion’s Mane, Pioppino, Chestnut and blue oyster mushrooms…”
- How did you come to realize that your life would revolve around mushrooms?
“I worked in the restaurant industry for most of my adult life. Then, in 2016, I moved to Nova Scotia and worked at a school. It gave me time to take a step back and think about what I wanted for my future. My former partner Gabriel and I started taking an interest in mushrooms: we foraged for and identified them, and learned about how to grow them. We never went back to the restaurant industry. We started a small business in the basement of a house, with just one shelf, and sold our mushrooms to a single customer. We were hooked: once you start working with mushrooms, it’s very hard to change paths.”
With that, Virginie opens the door to the mutant nursery. It is an isolated room whose only window overlooks the workshop, misted every ten minutes. It quickly becomes clear that here, humans adapt to the mushrooms, not the other way around. Across dozens of shelves, mushrooms in a variety of shapes and colours climb over blocks of substrate.
“I’ll try to put it in simple terms, but basically, we start with a mushroom cell that we place in a Petri dish containing sweetened agar-agar (editor’s note: a type of gel base in which organisms can grow). The mycelium then colonizes the dish, and a beautiful white fuzz appears on top. We use it in the subsequent stages until it eventually grows on the grain we use to colonize our substrate blocks, where the mushroom will ultimately grow. The whole process takes several dozen days. Then we make an incision in the bag, and the mushrooms emerge through it. We’re a bit like shepherds: we hope they come out in the right place and try to guide them. Sometimes, they don’t listen to us.”
