Advantages of PC Sheet:

The transmittance of PC board is up to 89%, which is comparable to glass. UV coating prevent the board from getting yellow under the sunlight as well as fogging, poor light transmittance.
The impact resistance is 250-300 times greater than ordinary glass, 30 times than acrylic glass, 20 times than tempered glass with the same thickness.
Our polycarbonate board only weigh the half of standard greenhouse glass. It cuts the costs in terms of transportation, handling, installation.
Flame retardant. National standard GB50222-95 confirms that our PC board is a non-flammable first grade. It’s ignition point is at 580°C.
Temperature adaptability: PC board does not occur cold-brittle at -40°C; Does not get soften at 125°C.
Energy saving: cool in summer, heat in winter. PC board has lower thermal conductivity than ordinary glass and plastic. Greatly reduces energy use.

Three-layer Inner Blackout System:

blackout curtain
  • The light deprivation screen is designed for sensitive plants that need photo-period control;
  • 100% shading rate, UV guarantee 5 years;
  • The light is reflected by the aluminum foil on the surface of the shading curtain, during the light-dark period, unwanted light accumulation can be prevented.
  • Although made of 3 layers, the closed curtain can still be collapsed into a small size, to ensure that the crop in its open to get maximum light. Has a good water permeability, the bottom of the curtain will not form condensation droplets.
  • Gearmotor with control box can open and close the shading net, including the timer.

Smart Control System:

Precise environment control ensures the nutrition, humidity, temperature and light balance and adjustment of plants from seedling to harvest.
