Plastic Black White Film Blackout Greenhouse for Medical Plant or Mushroom

Greenhouse black film and white film have different functions and effects in agricultural planting. The black film has good light-shielding and thermal insulation effects, and is suitable for planting in cold areas or winter; the white film has strong light transmission and cooling effects, and is suitable for planting in summer or hot areas. Choosing which membrane material to use needs to consider factors such as crops, seasons and regional climate.

Greenhouse black film and white film are covering film materials used for agricultural planting. They have some differences in functions and effects:

Light transmittance:

Black film: Black film has strong light-shielding properties, which can effectively prevent light from transmitting, reduce photosynthesis, and lower the temperature in the greenhouse.

White film: The white film has better light transmittance, allowing more light to pass through, which helps to improve photosynthesis efficiency and increase the light intensity in the greenhouse.

Thermal insulation effect:

Black film greenhouse: Due to its light-shielding properties, black film can keep the temperature inside the greenhouse higher at night, which is beneficial to heat preservation.

White film greenhouse: The white film has a strong reflection effect on sunlight, which can reduce the temperature rise inside the greenhouse during the day and help to cool down.

Soil temperature:

Black film greenhouse: Black film has strong heat absorption properties, which can help increase soil temperature and promote crop growth.

White film: White film has strong reflective properties, which can reduce the increase in soil temperature and help prevent soil overheating.

Crop growth:

Black film greenhouse: Suitable for planting in cold areas or winter, it helps to increase soil temperature and promote crop growth.

White film: Suitable for planting in summer or hot areas, it helps to cool down and provide shade, reducing the risk of heat damage to crops.
