The Semi-Closed Greenhouse: Handing the Air to the Machines — Can the Tropics Use It?
The semi-closed greenhouse swaps “open the vents and wait for wind” for “let the equipment supply the air”: openings shrink drastically while air-handling units and slight overpressure actively control the climate — buying insect exclusion, retained CO₂ and a more uniform environment. Born of the Dutch energy-saving context, its exam in the tropics and subtropics becomes heat rejection, dehumidification and electricity. A practical look at how it works, what it delivers, and who it does — and doesn’t — suit.
