Day length is a crop-management decision. Blackout screens create dark periods for crops that require them. Design considers joints, sidewalls and structural connections to limit light leaks, while coordinating ventilation and supplemental lighting.

Better decisions. More value in every cycle.
How this equipment supports everyday crop management.
More control of production timing
Define dark periods to support photoperiod-sensitive crops and plan their development stages.
Greater crop uniformity
Continuous closure with properly detailed joints and sides helps plants receive a consistent dark period.
Fewer management mismatches
Coordinate screens, lighting and ventilation to meet the light schedule while managing temperature and humidity during closure.
Define the dark period the crop needs
Blackout screens create dark periods for crops with specific photoperiod management. Timing follows the production programme: closing during the day or opening at night is one possible strategy, not a universal rule. The animation illustrates that operating example.
Sealing matters as much as fabric
Darkness depends on more than the overhead screen. End walls, sides, joints and equipment connections may admit light. The complete enclosure is designed to coordinate those surfaces and review potential leaks. Diagram transparency is only a visual aid to reveal the interior.
Photoperiod and climate work together
Closing also changes environmental exchange. Scheduling is therefore coordinated with ventilation, temperature, humidity and lighting. Operating times, actions and supervision criteria are agreed so light and dark periods support the crop while indoor conditions remain observable.
Want to programme light and darkness with automatic control?
Coordinate screen closure, lighting and ventilation with the photoperiod treatment defined by your team.
Automatic functions depend on the sensors, actuators and configuration of each project.

Frequently asked questions
What is a photoperiod screen for?
It enables scheduled dark periods for crops sensitive to day length. Programs depend on species and stage.
Is it the same as a thermal screen?
No. A photoperiod screen controls light transmission; a thermal screen prioritises energy exchange. Fabrics and objectives are selected separately.
Do sides need closing too?
The entire enclosure is assessed to limit light leaks at joints, ends and sides when the crop requires darkness.
How is heat managed during closure?
Programs coordinate ventilation, temperature and humidity. Blackout also requires environmental management during dark periods.
Can it integrate with lighting and Gaia?
Yes, with compatible equipment. Schedules and priorities align lighting, screens and climate with one program.
