Re: ozone

I think you mean carbon dioxide (CO2) tanks not oxygen tanks.  Remember
right plants use CO2 for photosynthesis and give off oxygen as by
product.   I think last summer/fall some people it the group were semi
serious but mostly joking about setting up some type of green house over
their plants with a hose connected to the exhaust pipe of their car as a
way to increase the amount C02. I should have payed more attention in my
biology and botany classes- then i would be able to remember more and
give a more exact answer.

I don't know about the effects of pollution on plants. Ozone is 03,
three oxygen atoms together.  So it is not toxic harmful to your plant.
ozone does act as a shield to filter out some of the ultraviolet suns
rays.  The higher the ozone levels, the more sheilding of the
ultraviolet rays would occur.  ultraviolet rays are needed by plants for
photosynthesis.  I have no idea how hight the ozone levels would have to
get before this would actually start negativily affecting your plant.
my guess, only a guess, is that plants are pretty hardy and that the
"high" levels of normal type pollution and ozone that you are talking
about would not harm your plants.

Does anyone know how pumpkins function on Code Red-Ozone Alert days??  
Let's see, we've got robotic water/fertilizer applicators and misting 
systems, sonic bug repellers, pyramids, matchmaker services and 
icehouses...  Is the next step oxygen tanks??  Hey Dan Shapiro - you may

need a another sensor and a new routine added to that program!

But my ozone question is serious - other than the heat of these days, 
what does the pollution do and is there any realistic way to mitigate 
negative effects?
