Question:
Is plant growth affected differently when exposed to artificial light instead of sunlight?



Replies:
Hello Marshall

Yes, plant growth can be affected by artificial lighting - but it depends on what type of lights are used.

Plants are best at using certain colors of light - blue light and red light are the best colors. Light from the sun has all the colors of light so plants grow well in light from the sun. Often artificial lights are either not strong enough or produce the wrong colors for the plants to be able to use the light and grow well. Consequently you need to buy special lights to grow plants under - these lights are very strong and produce the right colors for plant growth.

Thanks for the question.
