SCREEN
Shading and thermal screens
A screen does three jobs: cut peak radiation, hold heat at night, and manage light quality for the crop.
External screens cut solar load before it enters the house; internal screens manage light and heat inside. A thermal screen closes at dusk and can halve night losses.
Screens are chosen by openness ratio and material, then by how the control strategy uses them — a screen that stays closed all afternoon can cost more yield than it saves.
