The answer for me was yes. The light meter was the second item I bought,
after Rebecca Northen's book. I have found it almost irreplaceable as a
training tool. Many times authors will talk about growing something in
'Cattleya' light or some such blather. Well, what the heck is that
supposed to be when its at home??? And the trick about using your SLR
camera is just too weird, for me anyway. So the meter was/is a great
tool. Its the only way to be sure what you're 'getting'. Of course I had
to go overboard and buy a real nice one, but really, any meter will do.
I've often wondered if a meter that would quantify the color of light
might be helpful too, since plants photosynthesize in one color, bud in
another and find green to be a total waste of wavelength. *G* That would
have been helpful when I was growing under lights. Just to check on the
manufacturer's claims. Maybe help in determining when to re-lamp. Just a
Any relation to the book 'Death and Life of Bobby Z'? [Just kidding]
