America has real agricultural constraints: import dependence, record high diesel prices, water stress in many regions, extreme weather, labor pressure. But a constraint isn't automatically a controlled environment agriculture (CEA) opportunity, and CEA isn't one technology. CEA generally means growing crops in a protected and controlled environment, often indoors. It's a toolbox that runs from a simple shade house to a fully artificially lit vertical farm, and the right tool is generally whichever one is the least technologically intensive (and cheapest) system capable of solving a specific buyer's problem. For growers, developers and investors evaluating a project, the main question is: where does controlled production create enough additional value to outperform field production, imports, logistics improvements or a simpler protected system, and what does the evidence from projects already operating actually show?
The short answer: CEA makes sense in the U.S. where a specific buyer will pay for something field production or imports can't reliably deliver, such as disease-free plants, a steady local supply, year-round freshness or a distinct product. The four projects below each solve one of those problems, and our Oʻahu greenhouse model shows that the selling price, more than the technology, decides whether the numbers work.
Fresh produce imports have grown steadily: between 2007 and 2023, imports rose from roughly 50% to 59% of the fresh fruit and from roughly 20% to 35% of the fresh vegetables (excluding potatoes, sweet potatoes and mushrooms) available in the U.S. Mexico alone supplied more than 90% of U.S. fresh tomato imports and roughly nine in ten lettuce imports (92% by volume in 2024; 88% by value in 2022, per USDA data), even though imports cover only about 8% of U.S. lettuce availability.
That concentration became visible in 2026, when a Cyclospora outbreak that federal investigators linked, through traceback, to iceberg lettuce from Taylor Farms de México in central Mexico sickened 12,883 people across 21 states; CBS News reported that the FDA hadn't inspected the farm in seven years. Water and weather add further pressure: the U.S. recorded 27 weather and climate disasters that cost more than a billion dollars each, in 2024 alone, totaling roughly $182.7 billion. Labor availability adds a related pressure across specialty-crop production one that automation can ease but not eliminate, since it trades field labor for capital, energy and a different, more specialized workforce.
Each of the four examples below shows a different way controlled environment production creates value, for a specific buyer, at the level of control that the buyer's problem actually requires.
Florida's strawberry industry sources most of its transplants each fall from nurseries in California, Canada and the Appalachians, and that long, field-grown supply chain is how disease travels: a newly aggressive pathogen, Neopestalotiopsis, was first identified in Florida strawberry fields in the 2018-19 season and can destroy entire fields. The response so far has mostly been science, not commerce: the University of Florida's IFAS Extension runs a Strawberry Clean Plant Program supplying disease-tested starter plants to the out-of-state nurseries Florida depends on, but that's university-led research infrastructure, not yet a Florida-based commercial fix for the industry's own supply chain.
One company shows what that fix looks like once it's commercialized. Nourse Farms, a Massachusetts nursery backed by Solum Partners, an investment firm focused on food and agriculture, built a tissue-culture lab and a 7-acre greenhouse for foundation plants to produce virus-indexed strawberry, raspberry and blackberry plants for commercial fruit growers, and now names Neopestalotiopsis directly as a risk its propagation and testing program is built to manage, sending leaf samples to the University of Florida for ongoing disease monitoring. The buyers are nurseries and growers who need genetically uniform, disease-tested material that open-field propagation can't guarantee. It's a preview of what a Florida-specific fix might eventually look like, not proof that one exists yet.
Hawaiʻi imports an estimated 80–90% of its food, and shipping disruptions aren't hypothetical: over three weeks in May and June 2026, interisland carrier Young Brothers missed three of its twice-weekly barge runs to Molokaʻi, emptying grocery shelves and leading at least one Molokaʻi farmer to pay roughly double to airfreight his cucumbers to Oʻahu customers. Molokaʻi's produce itself arrives from the U.S. mainland via Honolulu, and Oʻahu sits on the same long supply chain. On Oʻahu's North Shore, the resort now known as The Ritz-Carlton Oʻahu, Turtle Bay (rebranded in August 2024) owns Kuilima Farm, across Kamehameha Highway from the resort. The farm combines a solar-powered hydroponic greenhouse with about 25 acres in active production. As of 2023–24, it produced about 2,000 pounds of produce a week, with roughly 800 pounds going directly to the resort and its restaurants, including its signature restaurant, Alaia. The hydroponic greenhouse alone was harvesting more than 350 pounds of lettuce a week in 2023. The rest of the farm's output is sold to wholesalers and retailers, with some greens bagged for the farm stand. The resort is the anchor buyer, and the value isn't lower cost; it's freshness and supply continuity that a supply chain stretching thousands of miles across the Pacific can't guarantee.
New England's winter produce still comes largely from California, Arizona, Mexico or imported greenhouse supply, and Little Leaf Farms, a Massachusetts hydroponic greenhouse company, has built a retail business around closing part of that gap. Its baby lettuce, romaine and spring mixes, grown hydroponically and marketed as delivered to stores in as little as a day, now reach more than 8,000 grocery stores, and Baldor Specialty Foods lists Little Leaf among its farm partners. The company has expanded aggressively, building a 40-acre greenhouse campus in McAdoo, Pennsylvania, and in August 2026 began commissioning a new campus in Manchester, Tennessee. The buyer here is the grocery retailer and its distributor, not an individual institution, and the value is consistency: a shorter, more predictable supply chain than long-distance winter shipping, at a volume large enough to hold shelf space against imported alternatives year-round.

Oishii, based in Jersey City, New Jersey, grows Japanese-varietal strawberries indoors year-round in the U.S., with its main production in a 237,000-square-foot solar-powered vertical farm in Phillipsburg, N.J. Its berries are pesticide-free, non-GMO and harvested at peak ripeness. CEO Hiroki Koga said in 2023 that he chose strawberries over leafy greens because they are a high-value crop that is hard to grow consistently, the opposite of the commodity lettuce business where many vertical farms have struggled.
The buyer here isn't a resort or a distributor; it's the shopper willing to pay for a premium product. Even Oishii's lowest price point, introduced in April 2026, is a 3-ounce box at $4.99 (about $26.60 per pound), and a 7.5-ounce pack of its Nikko berries retails at $7.99 (about $17 per pound). The company was in more than 300 retail locations and aiming to double that by the end of 2026, and in May 2026 it closed the first $150 million of a Series C round, bringing its total funding to more than $370 million.
It's worth being direct about what this example does and doesn't prove. Oishii is privately held, so its profitability can't be verified from public financials, and it has needed substantial outside capital to get here. What it does show is the mechanism: the most technologically intensive form of CEA is easiest to justify when it produces something buyers can't get any other way, at a price that can carry the cost of control.
Together they show that successful CEA projects don't start with a technology looking for somewhere to deploy it. They start with a constraint, a crop or product, and a buyer, then choose the level of environmental control capable of creating enough additional value to justify its cost.
Nourse Farms' value is control: pathogen-free genetics that protect downstream growers in a way a shipped, field-grown transplant can't guarantee. Kuilima Farm's value is proximity and dependability: freshness and hospitality integration that no import schedule can replicate. Little Leaf Farms' value is regional consistency: a shorter, more reliable supply chain that earns retail shelf space year-round. Oishii's value is differentiation: a premium product that shoppers pay for because they can't get it from the conventional field supply chain. Four different problems, four different buyers, four different levels of control, and in each case the system was sized to the value it needed to create, not the other way around. For anyone evaluating a new project, the lesson isn't which of these four categories to copy. It's to identify which specific mechanism (control, proximity, consistency or differentiation) a real buyer will actually pay for, before choosing a system to deliver it.
Real projects like these show where controlled production can create value. They don't prove that a new project, on a new site, with a new buyer, will be financially viable. That takes a model: crop, system, location, CAPEX, OPEX, yield, selling price and buyer commitment, tested together rather than assumed.
To see that in numbers, we built an illustrative scenario in Agritecture Designer: a small hydroponic greenhouse in central Oʻahu, loosely inspired by the Kuilima Farm example above. It grows small-head lettuce mainly for a resort's own kitchens, with any surplus sold to other hotels, in a state that in 2022 imported about 89% of the lettuce it consumed. The figures below are our own modeling assumptions, not Kuilima Farm's or the resort's actual numbers.

We ran the same greenhouse at two selling prices. The first, $8.33/lb, is the average per-pound price of Oʻahu-grown lettuce listed on Farm Link Hawaiʻi, a local food-delivery marketplace. It reflects the resort valuing its own greens at local retail. The second, $5.50/lb, is roughly the price at which the farm just covers its Year-1 operating costs.

*Net profit in Designer is shown after depreciation, full loan payments (principal and interest) and taxes.
Agritecture Designer results at $8.33/lb.
Same greenhouse at $5.50/lb. Only the selling price changes.
In both scenarios, CAPEX is $188,694, about three-quarters of it for grow systems and structures. At full output the greenhouse yields up to 25,903 lb a year, using 30,712 kWh of electricity and 606,688 gallons of water. Year-1 operating costs are about $81,000, and labor is by far the largest line at $58,273.
The two runs share the same greenhouse, crop and cost assumptions. The difference is entirely what the buyer pays. At $8.33/lb, the farm is profitable from Year 1 and pays back in about three and a half years. At $5.50/lb, it barely covers operating costs in Year 1, loses about $31,000 after depreciation and loan payments, and takes about eight years to pay back. Interpolating between the two runs, Year-1 net profit turns positive at roughly $7.80/lb. For context, Hawaiʻi farms received $2.76–$3.20/lb for lettuce in 2024, well below either scenario. At that price, this greenhouse wouldn't cover its operating costs in its early years.
So why model $5.50 or $8.33? Because $2.76–$3.20 is what farmers are paid, not what a resort pays once distributor markups, shipping and spoiled lettuce are added. The farm can reach these prices if the resort values its lettuce at what it would otherwise pay, if other hotels sign supply contracts, or if it grows specialty greens. On the plate, the difference is small: about $1 of lettuce per salad at $8.33/lb, versus about 40 cents at farm-gate prices. That extra 60 cents buys a premium ingredient, picked days rather than weeks before serving, with fresher greens that keep more of their nutrients, less waste, full traceability and a supply that doesn’t depend on the next shipment.
Five assumptions do most of the work in these results, and anyone evaluating a real project should test each one.
Price. Because most of the lettuce goes to the resort's own kitchens, its price is really an internal one: what the resort would otherwise pay for comparable lettuce, plus any premium it places on serving greens grown on its own farm. Surplus sold to other hotels would likely fetch less. The number to confirm first is what the resort pays its current supplier.
Management. Designer estimates the farm needs about 1.3 full-time equivalents of labor: roughly one person's worth of hands-on growing, harvesting and packing, plus small fractions of a head grower's and an operations manager's time. That assumes the expertise is shared with a larger operation, much as Kuilima Farm is managed by Pono Pacific. A standalone farm hiring a full-time head grower would face substantially higher labor costs.
Energy. Designer has no separate line for solar, so we folded the system's cost into the electricity rate. Because the greenhouse uses no supplemental lighting or heating, energy is a small cost either way: $4,300 a year at our solar estimate. Even at Hawaiian Electric's 2025 Oʻahu small-business average of 40.26¢/kWh, it would be about $12,400.
Trajectory. The projection assumes waste falls from 17% in Year 1 to 8% by Year 10, and that prices rise about 4% a year while costs rise about 2.5%. That gap widens margins automatically over time.
Ownership. The land is owned, so the model carries no rent or real-estate cost.
A model is the first step, not the last. Once it's built, an entrepreneur should weigh it against the realistic alternative, which here means continuing to import the same lettuce. That comparison has to go beyond purchase price, accounting for:
It should also count the value a farm creates beyond its produce. Here, the greenhouse could double as an agritourism amenity, much as Kuilima Farm already runs paid farm tours for guests and visitors.
None of this means a lettuce greenhouse on Oʻahu is a sure thing, or a bad bet. It means the result rests on a price, a buyer and an operating setup that have to be confirmed before construction begins. We didn't model a vertical farm here; Oishii shows the kind of premium that level of control needs to earn.
The pattern across all four examples, and in the Oʻahu model above, is the one this article opened with: the projects that work are the ones where the crop, the buyer and the facility type were matched from the start, not the ones running the most advanced system. The goal was never to maximize technology. It's to use the level of control a specific buyer's problem actually requires, no more and no less, and to know that before construction begins rather than after.
Agritecture Designer is a free tool built to test exactly that. Don't take feasibility for granted. Test it.
