I remember you showing me in 2004 what the field
fire fumes did to your plants, causing problems year after year.
Could that problem, different from what you
experience now, in fact have been caused by gases coming from
the panels
affected by heat, rather than the fire
fumes?
I am wondering if your current problem may be
caused by the two new materials you installed.
Could it be that new
polycarbonate panels and/or the new wet pad materials release gases fans
blow over the plants.?
Were your temperatures elevated above normal in
this hot summer we were having?
Something to consider, though I may be way off
base.
