Re: [APD] Re: Lights

Well, you could throw shop lights over the plants and
they'll do fine -- I mean the ones that cost about $20 and
come with bulbs in them. The diff in bulb color is purely
for your personal aesthetic tastes. The plants won't give
fig one way or the other. The amount of light will make a
whopping diff and after that, all the other things, like
nutrients levels, maintenance, will have much more effect
than you can pin on color temp -- with the exception maybe
of the degree of redness of a few plants in some
situations.

It will be a great day when all the manufacturers, using
the same measurement techniques, rate things like spectral
output, maybe PAR output,  90%-probable minimum life. etc,
and print it on the package and in nice big letters. :-)
