Coastal Farm Supply. It's funny to me how Shiva wants to
shoot things down when he/she doesn't even understand the physical
pricipals and methods that make fogging a good method
of spray delivery.

Obviously I want to stay away from ingesting chemicals, but
none of that was the question... nor is my choice of the potency
of chemicals the question... I was hoping someone has already
tried this approach of chemical delivery on ROSES, not start
an argument over chemical safety and it's effect on the
environment. You also make different choices on these types of
things when you own farm land with no neighbors compared to some
of you city folk, that's why I just want to learn about the roses.

Thanks again for those of you who responded, anyone else tried
this fogger method yet?

Is it a genuine fog of suspended particles
or is it an aerosol/paint gun effect.
There is a difference.

Can you tell me what the difference is, Theo? I didn't know there was
one.

The one in nature consists of
100% humidity and sudden chilling of
saturated air. In nature ideally all
the fog particles will have the same size
and charge so they do not immediately clump.

Since this is not reproducible
artificial fog machines use chemicals
such as glycols to stabilize the particles once formed.
The mixture is heat evaporated, slightly
compressed & pushed out into the open
where it quickly cools to form fog.
Stabilization is needed because the particles are so small
they will quickly evaporate even in 90% humidity.

I'm not even gonna consider oil based fog.

The aerosol effect tries to spray
particles small enough. but the particle
sizes are not even & there is no charge
so they quickly clump and gravity takes over
loosing the fog effect.

The big down side with aerosol sprays is that
the nozzles are extremely small. even the smallest
particle will clog the nozzle.
