    Actually, I was under the impression that anything that grows
_doesn't_
need UV light. Which is why humans have melanin and why we burn under
sunlight with UV in it. UV light tends to sterilise and destroy organic
molecules, like DNA and so on. Remember the hole in the ozone layer? The
ozone layer filters out UV light, except where the hole is.

    The was one recent SF story collection (Tuf Voyaging?) that in one
story, had the colonists being attacked by a huge variety of strange
creatures every so often. These war creatures were genetically
engineered,
psionically, and were grown to remove the sudden 'plague' of humans.
