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...)
