[Plant-education] vermiculite and other dusty materials
(by carl.pike from fandm.edu)

In designing a new greenhouse, we are concerned about dust during
mixing and potting operations. This leads to 2 questions -
1. Can anyone recommend a system for dust removal that could be
installed over the potting bench? Someone suggested the devices used
around woodworking machinery. We've heard about "snorkels" that are
used in medical settings.
2. I have heard particular concerns about the safety of vermiculite.
I was "brought up" using vermiculite for seedlings (peas, oats, etc.)
either in the light or dark when the growth period was just a week or
two. Are there some types of vermiculite that are of less concern?
What are people using instead?
Many thanks. Carl
