If the vegetables are growing illuminated exclusively by blue light,
will they be different in taste from the vegetables which are growing
illuminated by, say, exclusively green light ? What would be the
taste ?
(I presume that the chlorofylle in the plants needs to be illuminated
by the light of a certain wavelength or above, in order for the
chemical reaction of photosynthesis to take place. This will probably
result in different taste molecules been formed. That's all I know...) |

What would happen to you if you only saw blue light all your life? How would
things be different? Would your poop still smell bad? Just wandering......

Most plants require red and blue light for proper growth. Plants
grown exclusively under green light would probably die, which would
affect the taste. |

I actually did an experiment on this back in high school. I tried to grow
green beans using red light and blue light. I didn't get any actual beans.
They need a mix of light to produce. |

You'd think green vegetables were green because of the light they
absorb, but they're green because they don't use green light at
all, it's reflected. I always found that puzzling.
Sorry for passing on the multiple cross-posts.

Baladi might try using tinted bulbs of different wattage to create two
distinct mixed spectra and see what happens Re: growth and taste. |

Not quite what you want but mentions tomato's taste effected by light:http://pubs.acs.org/cen/coverstory/85/8544cover.html
Thanks everyone who answered. The question is still open. |

The question is open to what??? Maybe someone will tell you what you
want to hear? Not trying to be terse, but unless tomatoes are grown
in full sun with cool nights, they will be like eating cardboard; and
that's IF they set fruit. The only way to grow tomatoes in winter is
in a greenhouse and even then there is not enough light. If you live
closer to the equator where you have evenly lit days in all seasons,
maybe, but not likely. |

Photosynthetic processes are very wavelength-dependent. Also involved
is the amount of time between bouts of photochemically-triggered
reactions that is available to do the 'bookkeeping' of flushing away
byproducts to keep their concentrations below dangerous levels and
replenishing the raw materials needed for the photosynthesis.
Here is just a glimpse at the complexity of the situation:

As to "taste", well, how educated is your palate?

Don't, uh, indoor farmers of recreational pharmaceuticals keep their
crops illuminated 24/7?

Most plants need at least 4 hr. of reduced illumination. Marijuana may
be an exception.
