With no soil or growing seasons, this Ontario startup is working to feed a hotter world

Born in the pandemic, London-based Farmia has left its old home and is set to expand its business A London, Ont., agriculture technology company has announced an ambitious new plan that will see its operations move from a former cereal factory to a local mushroom farm, where it will expand production and create a zero-waste farm system it says will help feed an increasingly hotter world. 

Farmia first moved to London in the fall of 2021, taking up residence inside the cavernous warehouse of the city's former Kellogg's cereal plant — enough space for Farmia's soaring towers of hydroponic greenery to stretch to the ceiling, filling the otherwise dark space with vertical rows of bright leafy greens, nurtured under the glow of high tech grow lights.

"We chose Kellogg because its the biggest indoor entertainment area in Canada," Mohamed Zayed, Farmia's co-founder and chief operating officer told CBC News, noting the large windows overlooking the huge room allowed the public to get a peek under the hood of a technology Zayed hopes will help change the planet for the better.

"It is very sustainable. We use a lot less space and a lot fewer resources to create a lot more product consistently and year-round."

Locally-grown food for a hotter world

With no soil and no growing seasons, Zayed's technology can reliably produce 640 edible plants in less time than it takes to grow a similar crop outdoors, using the same amount of water it takes for a 10-minute shower — a technology Zayed said can eliminate the wild price fluctuations and e. coli outbreaks that come with the way we farm now.

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
