White greenhouse plastic offers several important advantages for plant growth. According to the site “GreenhouseCover,” white (or diffused) plastic sheeting helps by diffusing and reflecting sunlight rather than allowing harsh direct sunlight — which results in more even light distribution. This helps plants grow more uniformly and reduces the risk of scorching or uneven growth due to intense light. Moreover, white plastic helps regulate temperature inside a greenhouse: it reflects excess heat on sunny days to prevent overheating, while helping to maintain warmth on cooler days creating a stable environment that supports consistent growth. Also, when used as ground cover or lining, white sheeting can help suppress weeds by blocking their sunlight, reducing competition for resources.
