Can red light grow plants

Photosynthesis is best in red light and very poor in green light. Chlorophylls absorb the red light and carotenoids absorb blue-green light, but green light is not effectively absorbed by photosynthetic pigments in plants; therefore, light of this color is either reflected by leaves or passes through the leaves. This is why plants are green. Red light is the most effective in photosynthesis because it has exactly the right amount of energy to energize, or excite chlorophyll electrons and boost them out of their orbits to a higher energy level.

Actually red light does not help plants grow faster it is blue light.

I did an experiment covering plants with: Clear cellophane, Blue cellophane, Red cellophane and green cellophane and the red was the third slowest and the blue one was the fastest.

Red light IS best for photosynthesis, which is responsible for making glucose for your plant to make energy. While Blue light is best for plant GROWTH. Green Light is just worthless except for making our plants green looking.
