now, if you are considering unichromatic light the answer would be blue and red. i think red outplays blue, but not sure. a plant, would however, grow the least in green light. but when it comes to white light, it is the best. as white contains all the colours of the specrum and together enhance the action of the photosynthetic pigments

If by color you mean the k value, it depends on the plants. You can get hylide lights (commercial greenhouses are really the ones that use these..or pot growers LOL) but they are very expensive to buy and maintain and in electricity costs. If you are just looking for a simple application like for houseplants there are what are called Gro-Lights available which are pretty much wide spectrum.

Keep in mind that darkness for most plants is JUST as important as lighting. Quite a few plants do their growing based on the lenght of darkness they recieve rather than the length of light.

Here's a link that should help you a bit:

HTH, good luck!

It's very dependent on the plant. As a general rule, try to provide as broad a spectrum as possible. For some specific plants, a particular color of soil mulch or other ground cover is helpful; for instance, a tomato-red ground cover has been shown to speed the growth of tomato plants, and the ripening of fruit.

Plants reflect green wavelengths of light hence they appear green.
Therefore colours at the far end of the spectrum such as red and blue would be most ideal for absorption

The best wavelength of light is plant-specific, although most plants absorb ultraviolet the best.

Blue

in case you insure you have equivalent intensity of sunshine from each and every of the three lamps. the terrific advance could be below white mild, 2d below pink mild, and least with green mild. There won't be measurable distinction in merely one week. bear in recommendations that below damaging mild situations the plant might actually advance elongated yet weaker. advance could be measured by making use of the quantity of biomass (dry weight) of each and every of the communities of flora. you're able to have assorted flora starting to be below each and every lighting fixtures problem to cut back random possibility occurrences that would happen.
