Greenhouse blackout screen (also called a blackout curtain, light deprivation screen, or climate screen) is a specialized retractable fabric system installed inside or on greenhouses to block nearly all external light, typically achieving 99.9% to 100% light exclusion.
Blackout screens are usually made from knitted or woven materials like polyester, polyolefin, and aluminum layers. The aluminum coating reflects heat and light, while some designs feature multiple layers (single or double) for enhanced performance. Many are flame-retardant and UV-stable for durability.
Photoperiod control — Manipulates day length to induce flowering or control growth cycles in short-day plants (e.g., chrysanthemums, gerberas, kalanchoa).
• Light deprivation — Commonly used in cannabis/hemp cultivation to force multiple harvests per year by simulating shorter days.
• Preventing light pollution — Blocks artificial grow lights from escaping at night, complying with regulations and avoiding disturbances.
• Energy savings — Retains heat at night (up to 70% reduction in heating costs) and provides cooling/shading during the day.
• Supplemental lighting efficiency — Contains internal lights for uniform distribution and reduced external leakage.

1. How does the double-layered design good for my plants?
The double-layered design ensures more than 99.9% blackout, providing the darkness that some plants require for optimal growth. It can prevent 99.9% sunlight out.
2. What's difference from 2 layer and 3 layer greenhouse blackout screen?
3 layer greenhouse is mainly for grow cannabis, 3 layer blackout screen can make 100% sunlight out to keep Cannabis grow the best situation!
2 layer blackout screen can used for grow chrysanthemum , mushrooms and other plants .
3. Does the screen help in cooling the greenhouse?
Yes, when the reflective upper surface is chosen, it aids in effective cooling
4. ls the screen energy efficient?
Yes, especially when one layer is aluminum, it leads to significant energy savings
5.How does the screen manage moisture?
The design of the Blackout shade screen ensures good moisture management, preventing excessive dampness that could harm plants.
