Explanation:
Detailed explanation-1: -Blue light promotes the growth of leaves and stems, creating a fuller and denser plant. Fluorescent lights are able to stimulate leaf and stem growth in green plants.
Detailed explanation-2: -In a greenhouse, the intensity of light can range from as much as 130, 000 lux on a clear summer day to less than 3, 000 lux on overcast winter days. Different crops prefer different light levels.
Detailed explanation-3: -Red and blue have the greatest impact on plant growth. Green light is least effective (the reflection of green light gives the green color to plants). Blue light is primarily responsible for vegetative leaf growth. Red light, when combined with blue light, encourages flowering.
