Can Different types of light affect plant growth?

plants need ultraviolet light to photosynthesize. If you put a plant in a sealed room (no sunlight) and used a light that didn't emit UV rays, it would not grow

Sunlight, duh. "Grow lights" are better than, say, incandescents, but there's no substitute for sunlight. Plants were growing long before people brought them inside and tried to grow them with artificial light. Do you mean UV light like in a tanning bed, or one of those grow-light bulbs? Sunlight is best, hands-down. The rest have a bit of UV light, but not enough of the kind of light plants like best. But as far as the spectrum of each...dunno. You'd have to check Consumer Reports or something, maybe something on indoor gardening.

Yes, thay can affect plant growth, and Sunlight is by far the best.

there are different types of lights that you can use for plant growth. Mainly separated into 2 catagories. High-intensity lights and low-intensity lights. Low-intensity are regular fluorescent lights. With lumens (unit of measurement for the brightness of light) ranging from 100 to 5000. Then there are High-Intensity lights such as High Pressure Sodium(HPS), and Metal Hallide (MH) lights. These lights can produce anywhere from 10,000-30,000 lumens but are much more costly to use. you need to plug them into those big outlets for the dryer. UV lights and regular yellow house lights have no effect on plant growth. So if you plan on growing with fluorescent lights, i suggest that you buy a couple of them to produce more lumens. Go to a pet store and ask them about the grow-lights they use in the fish tanks. they produce more lumens than normal fluorescent lights that you would use for a hallway.
