An honest assessment of greenhouse farming profitability: realistic payback periods, margin structure by crop, the operating costs that decide outcomes, and when projects do not work.

Well-executed commercial greenhouse projects typically return capital in four to eight years. Poorly executed ones do not return it at all. Protected cultivation raises yield per square metre several times over open field production, but it also converts a weather-dependent business into a capital and energy intensive one. The technology is not what determines the outcome.
Across the projects we assess, four factors explain most of the variance between facilities using near-identical technology. None of them are engineering decisions.
Different crops produce profit in different ways. High-wire vegetables generate volume at thin unit margins and are highly sensitive to energy cost. Berries carry higher unit prices and higher labour intensity. Leafy greens turn capital over fastest but compete closest to commodity pricing.
Energy and labour together typically account for 55 to 75 percent of operating cost in a heated facility. Both are commonly underestimated at feasibility stage, and both are where the difference between a modelled and an actual return usually originates.
We advise against proceeding more often than clients expect. The recurring situations below are ones where the model rarely closes regardless of how well the facility is engineered.
Treat any projection that presents a single scenario as marketing rather than analysis. A credible model shows sensitivity to energy price, yield shortfall and price realisation, and it accounts for the establishment period during which the facility consumes cash without producing at full rate.
In our experience the highest-return decisions are made before construction and cost comparatively little: correcting the water strategy, sizing the screen package properly, designing the layout around harvest labour, and contracting an experienced grower. Each of these tends to outperform incremental spending on structure specification.
| Crop | Capital intensity | Time to mature yield | Typical payback | Primary risk |
|---|---|---|---|---|
| Tomato (high-wire) | High | 2nd cycle | 5 – 8 years | Energy price exposure |
| Cucumber | High | 1st – 2nd cycle | 4 – 7 years | Price volatility |
| Strawberry (table-top) | Moderate | 1st – 2nd season | 4 – 6 years | Harvest labour supply |
| Blueberry (substrate) | Moderate | Year 3 – 5 | 6 – 9 years | Long establishment period |
| Lettuce / herbs | Moderate | 1st cycle | 4 – 6 years | Commodity price pressure |

The advisory desk builds the feasibility and capital models that Aegis clients present to boards and lenders. Work focuses on cost per square metre, energy cost per kilogram, phased capital deployment and the assumptions that determine whether a project is financeable.
FAQ
Four to eight years for a well-executed facility with contracted market access. Perennial berry projects run longer because the crop takes three to five years to reach mature yield. Projections below four years usually rest on optimistic price or yield assumptions.
Mature, well-run facilities commonly operate at 15 to 30 percent EBITDA margins. Margins compress sharply with energy price spikes or when output is sold into spot markets rather than under contract.
Below roughly two hectares, fixed overhead — management, climate control, packing infrastructure — becomes difficult to carry per square metre. Small facilities can work in high-value niche markets with direct sales, but the economics differ fundamentally from commercial supply.
In heated climates it is usually the single largest swing factor. A facility with dual screens and heat buffering can operate at 25 to 40 percent lower energy cost per kilogram than the same structure without them, which is often the difference between viable and marginal.
