Mike -- I should have thought of this yesterday. I'm listing the group
instructions below, as well as the procedure to get to the discussion in
question.
For those of you interested, there are many other groups specifically for
discussions of homeschooling, in its many varieties. Yahoogroups.com might
be a good place to start a search, but I'm sure those already involved will
have resources to recommend.
The discussion I mentioned was on the Homestead group. To join, go to:
http://lyris.unc.edu/cgi-bin/lyris.pl?enter=HOMESTEAD
After you've subscribed, go to read messages, then search on date (not
subject, because it's not that clear) beginning with 2/3/2001. You'll have
200 messages available on that screen to investigate. The discussion on
Teaching Writing Skills was the innocent beginning.
Just for the record, I have no problem with the methods used by any parent
to educate their children. My only objection was in the blanket statements
regarding teachers, when I personally know many who go above and beyond
daily in order to do more than what the state requires of them.

Subject: Gnatrol
From: "Jay Myers"
Date: Tue, 27 Mar 2001 07:59:13 -0600
I bought the Gnatrol ($25 / gal) from Southern Agricultural Insecticides,
Inc. (800) 477-3285 in Palmetto, Fl. They also have outlets in
Hendersonville, N.C., and Boone, N.C. They are a large commercial supplier
and have several well versed folks (PhD types with field experience). Only
problem I find is their packaging is sometimes larger than I need, but
that's why you get the better price. Their smallest Gnatrol comes in 2.5
Gal.
I get M-Pede (same as Safer soap) for about $40 / 2.5 gal. At Home Depot
Safer Soap costs about $13 for a Quart (if my memory is correct), or about
$130 for the same amount.
I also buy Perlite, Hydro fertilizer, calcium nitrate, and lots of other
stuff from them.
I have nothing to do with the company, but have always pleased with my
dealings with them.

Carlos,
The fact that you are having the same symptoms in your lettuce plants in BA and
La Pampa that we have in Asuncion is quite serious and a clear indication that
global climate changes are affecting plant growth.
Considering that your summer temperatures are significantly lower than ours, I
wonder if high temperatures are the main reason for the elongation of lettuce
plants. Please remember that our summer temperatures are normally quite higher
than 30ºC and generally around 38ºC plus minus 2ºC, but we never had this
problem before.
Have you considered that maybe the solar spectrum has changed with the hole in
the ozone layer? Do you think this could be the problem or at least part of the
problem?
Although I wouldn't rule out the influence of pressures, I don't think
atmospheric pressures are the problem because you are complaining of unusual LOW
pressures but we had rather more HIGH pressures than normal during this summer.
Best regards,
Juan
