Purple-light Greenhouse Film

(1) Excellent Anti-drip Performance: Water vapor does not form droplets on the film surface; instead, it flows down smoothly along the inclined surface.
(2) Higher Light Transmittance: Increases light transmittance by 10-20%.
(3) Superior Heat Retention: Raises the average temperature inside the greenhouse by 2-4°C and the soil temperature by 0.5-2°C.
(4) Disease Prevention: Helps inhibit viruses and reduce seedling rot.
(5) Long-lasting Anti-drip Effect: The anti-drip period lasts for more than 3 months.
(6) Growth Regulation: Promotes uniform and robust seedling growth.
(7) Controls Vegetative Growth: Purple light helps control the vegetative growth of crops and prevents them from becoming leggy (overgrown). It encourages roots to grow deeper, resulting in plumper fruits with better taste, significantly higher vitamin content, and drastically reduced nitrate levels.
(8) Promotes Crop Development: Purple light promotes the development of short-day vegetables and crops that are less sensitive to day length, such as tomatoes, eggplants, cucumbers, cowpeas, Chinese chives, spinach, crown daisy, and zucchini. Therefore, purple light is the key spectrum for the formation of product organs (fruits).
