Maybe someone can help me?  I'm trying to grow aquatic and semi-aquatic
plants in aquariums.  In the aquarium hobby there is debate going on as to
type artificial light that is best.  One idea is that plants only use light
in two frequencies, one at the red end of the visible spectrum and the other
in the blue end of the visible spectrum.  A second idea idea is that plants
need all frequencies of light.	A third idea says that plants simply need
extremely bright light for the stomata to open. Also a friend of mine claims
that plants don't need a period of darkness,  that they will do just fine
with light 24 hrs a day. This doesn't make sense to me but he has more
experience in botany than me so I don't argue.

If anyone could give me some insight I would greatly appreciate it.

Thanks,
  Grover
