Why Research on Vertical Farms Doesn't Translate to the Floor: A Structural Divide

2026-04-14

Vertical farming is an industry close to science. Lighting, HVAC, nutrient solution, environmental control — none of it works without a foundation in research.

And yet, when you bring the conditions described in a paper into a commercial facility, things often don’t work. The research lab’s “optimum” is not the same as the “optimum” for a facility shipping thousands of plants every day.

This article looks at why research findings are difficult to use directly on the floor, and how to read them in a way that turns them into practical knowledge.

Why What’s Written in the Papers Doesn’t Work

When I was working on the floor, I read a lot of specialist books and papers on cultivation techniques. Looking for any clue that might improve the operation. But when I actually tried to apply the growing methods described, they often didn’t fit.

There are three main reasons. First, the cost perspective of replicating conditions in a commercial facility is missing. A paper might say “yield improved 20% under these conditions,” but the cost of replicating those conditions in a commercial facility is never mentioned. Second is the scale problem: a lab experiment on a few to a few dozen plants and a commercial facility managing thousands of plants are operating under completely different conditions. A method that works in the lab often stops working the moment you try to scale it up. Third is the difference in growing environment. A research lab can precisely control temperature, humidity, and light. In a commercial facility, HVAC capacity has limits, the environment varies by shelf position, and outdoor conditions introduce seasonal variation. “Optimal conditions” as defined in a lab are hard to replicate in a real facility.

Why Research That Can’t Be Used in Commercial Facilities Gets Produced

This isn’t a case of researchers being at fault. It’s a structural problem.

University researchers are evaluated for publishing papers. Paper quality, citation count, impact factor. Whether a study was ever applied in a real facility almost never factors into the evaluation.

So the way research topics are selected prioritizes “academic novelty.” The starting point isn’t “can this solve a problem operators are struggling with?” it’s “has anyone studied this yet?”

The result is a steady output of research that is scientifically valuable but difficult to apply in commercial facilities. This isn’t specific to vertical farming — it’s a structural issue common to agricultural research broadly.

Researchers Moving Toward the Floor

In the middle of all this, there is a development worth paying attention to.

Ricardo Hernandez, Associate Professor at North Carolina State University (NC State), has articulated a research approach that prioritizes “actual impact for growers over academic interest” (Hortidaily, 2026).

The CEA Coalition led by Hernandez operates a system where growers submit their problems directly, suppliers vote on which problems have the biggest impact, and CEA Coalition uses those results to set research priorities. Rather than researchers deciding “what to study,” the floor decides “what to solve.”

Concrete results are emerging. Hernandez’s team collaborated with aerospace engineering experts to reduce the time it takes to model airflow in a greenhouse from “two to three days” down to minutes. This rapid airflow modeling technique is already being put to use in real greenhouse design work. Hernandez’s statement — “I want to shorten the time from research to practice. The best way to do that is to get direct feedback from industry” — is an unusual thing for a researcher to say, and it reflects exactly the stance the vertical farming industry needs.

How You Get Practical Knowledge

Going through papers and specialist books, identifying content that might be useful, actually testing it, and converting it into know-how — that takes time. Reading one book doesn’t change the floor overnight. You run trial and error over years, and only then does something earn the right to be called “this actually works.” That’s the know-how behind what I share on this site.

Researchers moving toward the floor is a welcome development. But the structural divide won’t close overnight. Operators also need the capability to “read research, test it, and make it their own” — and that capability links directly to long-term improvement and competitiveness. Try to use research as-is and you’ll fail. Ignore it and you’ll fall behind. Closing the gap between the two is something the floor side also has to work at.
