Detailed explanation-1: -Red light stimulates the growth of stems and flowers and boosts fruit production. It also aides in chlorophyll production. Indoor gardeners need to use light in the red band of the light spectrum if they want their plants to bloom. Red light is also necessary for growing vegetables indoors.

Detailed explanation-2: -Red light promotes flowering and fruit. Selecting red or blue bulbs give gardeners the option to select for different growth characteristics. Commercial growers looking to harvest a specialty crop on schedule may begin with a full spectrum bulb, then swap to red light bulbs to prompt flowering.

Detailed explanation-3: -Full-spectrum sunlight contains a high amount of red light. Meaning it has the effect of stimulating chlorophyll B production as well as fruiting, flowering and speeding up photosynthesis. General outdoor plants will receive a fair amount of red light to grow healthily.

Detailed explanation-4: -Red light is highly effective at regulating growth and development for plants. Red light helps to flower and fruit and prolong flowering. It can greatly enhance the photosynthesis of plants and promote the growth of plants.

Detailed explanation-5: -Red and blue light is believed to have a higher quantum yield of CO2 assimilation. The blue and red parts of the spectrum are effective to satisfy the energy requirement of plants. Hence plants absorb these two colors more than any other color.
