Is there a special kind of light that can make plants grow?

Question

Its for a science project and I'm trying to make them grow faster.

Answer 1

Yes! plants absorb red light and blue light and reflect green light, which makes them appear green in color, so red light and blue light are best. Use a fluorescent bulb (not a regular bulb). The best are available at pet stores or home improvement stores, often called "full spectrum" or "plant light," but any fluorescent bulb will do. If not that, sunlight is, of course, ideal, but different plants need different amounts of it. If you're trying to grow a "full sun" plant indoors, you'll need a hell of a lot of artificial light. If you are growing a "shade" plant or "partial sun" plant, you might need 100 watts of lighting total, at a distance of 1 foot away from the plant.

Answer 2

Yes, in the visible light spectrum, the color on the opposite end of the spectrum from the original plant's color.
Ex: 1)red light would help green plants grow
2)blue light would help orange plants grow

Answer 3

plants need light from all spectrums in order for them to grow. There are special bulbs for this at the hardware store.

Answer 4

Plants require red light and blue light. For sun loving plants, provide 2000 umol photons/m2/sec for 16 hours a day.

Answer 5

you can buy grow bulbs in many types and wattages
they produce an optimized spectrum for plants (supposedly)
They are not that expensive WalMart carries them

Answer 6

Yes its called a "Gro-light" ( spelling?) and is readily available. Basement /closet pot growers LOVE 'em!

Answer 7

sunlight works pretty good

Answer 8

yeah GROWLIGHT
