The Cost of a Cucumber: When Technology Replaces Common Sense

I've been thinking a lot about greenhouses and the cost of producing food, especially as we head into another Canadian winter.

We've become so accustomed to having everything available all year long that we rarely stop to consider what it actually takes to make that possible.

Tomatoes in January. Cucumbers in February. Fresh strawberries whenever we want them.

And while greenhouse technology has made some incredible things possible, I think there's a much bigger conversation we should be having.

Are we building a food system that works with nature, or one that becomes increasingly expensive because we're constantly trying to control it?

A greenhouse allows us to manipulate growing conditions. We can add heat, artificial lighting, irrigation, ventilation and climate controls to produce food when the natural environment wouldn't otherwise allow it.

But every one of those systems has a cost.

There's the infrastructure itself, the energy required to operate it, the maintenance, the technology and the resources needed to keep everything functioning.

And eventually, those costs have to be recovered through the price of food.

Now, I'm not suggesting greenhouses don't have a place. They absolutely do. In fact, simple greenhouses, hoop houses, cold frames and other season-extension methods can be incredibly valuable.

But there's a difference between extending a natural growing season and attempting to recreate summer in the middle of winter.

And I think that distinction matters.

What if we focused on extending the season instead?

Imagine a food system built around growing as much as possible during our natural growing season, extending production into the colder months using practical, low-energy methods, and preserving the abundance for the months when fresh production becomes more difficult.

Instead of relying entirely on expensive infrastructure to produce the same crops twelve months a year, we could be growing a greater variety of crops suited to our climate and the changing seasons.

Cold-hardy greens, root vegetables, squash, cabbage, potatoes, onions and countless other crops can be grown, harvested or stored in ways that extend their availability well beyond the summer.

We could be using unheated hoop houses, row covers, cold frames, root cellars, succession planting and better storage practices.

And we could be teaching people how to do it.

This is the kind of practical knowledge I believe we've lost, and the kind of education I want to bring back through Red Maple Farm School.

There's more at stake than the price of food

When we design growing systems around the natural environment, there are opportunities to reduce energy consumption, limit unnecessary inputs and make better use of the resources already available to us.

We can build healthier soils, encourage biodiversity, use integrated pest management and reduce our dependence on chemical inputs where appropriate.

That doesn't mean greenhouse food is automatically less healthy or uses more chemicals. Some controlled growing environments are extremely efficient and use fewer pesticides than outdoor production.

But it does mean we should be asking whether the technology we're investing in is actually reducing our dependence on resources, or simply replacing one dependency with another.

Because efficiency isn't just about how much food we can produce in a square foot. It's also about how much energy, infrastructure and money it takes to produce it.

And when we consider the entire food system, we also need to look at transportation, refrigeration, storage, packaging and food waste.

A food system should be measured by more than production volume alone.

What about the farmers?

This is where I think we have an enormous opportunity.

Rather than expecting every farmer to invest in expensive year-round production infrastructure, why aren't we putting more effort into creating a distribution system that connects seasonal producers with customers throughout the year?

One farm grows early greens. Another specializes in storage crops. Another produces fruit. Another raises livestock. Another uses season-extension techniques to keep fresh produce available later into the year.

And a shared distribution network brings those products together.

That's exactly the kind of infrastructure I've been building through Small Scale Farms.

Instead of every farmer needing to produce everything, every season, we create a system where farmers can specialize, cooperate through commerce and collectively provide a more consistent food supply.

We don't need every farm to become a year-round greenhouse. We need a food system that knows how to work with what our farms can naturally produce.

And what does that mean for consumers?

It means understanding that food has seasons.

It means recognizing the value of produce when it's abundant, learning how to preserve it, and making better use of crops that store naturally.

It means reconnecting people with the realities of growing food rather than expecting the same selection every day of the year.

And it means investing in the infrastructure that makes seasonal food accessible, affordable and practical for families.

I believe there's a tremendous economic opportunity in this approach.

More small farms. More diversified production. More education. More food preservation. More shared storage and distribution. And more money circulating between farmers, businesses and the communities they serve.

Not because we've eliminated technology, but because we've learned to use it where it makes the most sense.

I don't think the future of food should depend entirely on our ability to control nature.

I think it should depend on how well we understand it, how intelligently we work with it, and how effectively we connect the people producing food with the people who need it.

Because perhaps the greatest innovation we need isn't another way to grow tomatoes in January.

Perhaps it's a food system that makes better use of everything we can grow from March through November, and knows how to feed us through the months in between.
