Modern agriculture and controlled environment agriculture (CEA) are advancing at an incredible pace. New sensors, robotics, artificial intelligence, automation systems, digital twins, and data platforms seem to emerge every week. The promise is compelling: greater precision, higher yields, reduced labour, and more efficient food production. But amidst this rapid technological progress, an important question is often overlooked: Are we solving problems, or are we creating new ones? Technology...

In modern hydroponic farming, we optimise what we can see — leaves, fruits, stems, flowers. But beneath every crop lies something largely ignored: The root system. In most commercial operations, roots are treated as waste. At harvest, they are removed together with rockwool, coco coir, peat plugs, or other disposable growing media. They are composted, sent to landfill, or diverted into anaerobic digesters to generate biogas. That is often described as “circular”. But is it truly...

For years, vertical farming has been framed as a breakthrough: climate-proof, efficient, local, and endlessly scalable. And to a point, that optimism was justified. Controlled-environment agriculture has delivered consistent crops in places where traditional agriculture struggles. It has shown what’s possible when growing conditions can be engineered rather than left to weather patterns and seasons. But before diving in, it’s worth clarifying what we mean by vertical farming . It’s easy to...
