Re: [AGA-mcm] [Fwd: Re:Plant Research project] but it doesn't sound like science

["S. Hieber" <shieber@yahoo.com>]

I could be wrong. They might have a protocol; but it
doesn't sound like it.

I don't see any reason not to help advertize,; I'm all for
encouraging interest and activity inthe hobby. But this
event doesn't sound like the kind of research that would be
worthy of a grant -- not that anybody is asking for one. It
doesn't sound at all like it will be adding to the science
but collecting lots of anecdotal info from a variety of
setups without control conditions. Kelvin ratings are not
very good indicators of the sprectral output of a bulb and
spectral output is the thing beside intensity that is most
likely to have an effect on plant growth. So that alone
will make the results of the "experiment" very
inconclusive. If they actually have spectral output graphs
for the bulbs, or better yet, actually measure the output
across the spectrum, then they might have something --
assuming, of course, they controlled for everything else
that effects plant growth. If it's just a bunch of people
using diff bulbs, I see this adding more to the myths than
the science.

And I'm in a *good* mood today ;-)
