Climate systems.

The promise of a high-tech greenhouse is captured in a single idea: whatever happens outside, the crop never notices. Delivering that means holding the growing climate — a constantly shifting equilibrium of temperature, humidity, light and CO₂ — steady in the crop's ideal band while the weather beyond the glass does whatever it likes. No single device achieves it; a set of complementary systems working under one control strategy does.

Each system holds one part of that equilibrium. Heating and cooling hold the temperature line, keeping the crop warm on cold nights and shedding heat on hot afternoons. Humidity control keeps transpiration healthy by managing the vapour pressure deficit, so the crop drinks steadily and condensation — and the fungal disease it invites — is avoided. CO₂ enrichment feeds photosynthesis its raw material, lifting yield when light is plentiful. And because these systems constantly interact — a screen changes the heating load, ventilation dumps CO₂ along with heat — they are coordinated by the climate computer rather than run independently.

Which systems a given project actually needs, and how much of each, follows directly from the local climate profile rather than from a fixed template. Heating dominates the design in cold climates, where the challenge is retaining warmth through long winters. Cooling and humidity control dominate in hot and humid ones, where shedding heat and moisture is the daily battle. Most locations need a blend, sized to the extremes the site will actually see across three years of data, not to its comfortable averages.

Getting that mix right — enough capacity to hold the line on the worst day, without paying for systems the climate never calls on — is the essence of climate engineering, and it is where the crop's performance and the operation's running costs are both decided. Explore the individual systems below, or send your location and let the climate profile tell us which ones earn their place. Get in touch to design your climate systems.
