Lunar soil, is it good for plants?

Brilliant work Bill. I feel inspired. I just started
gardening this year, got myself a garden very close
to Martian conditions... near Uppsala, Sweden.

Coincidentally, I am growing Mexican koriander. Please consider
this is also important for Mexican foods, like Salsa Verde. My
land is 10x100 meters and I am putting up a shelter and greenhouse.
My background is molecular medicine, so I have some biology
training. We were just discussing amongst some of the other
gardeners there, some more serious science. You have revitalized
my interests.

I would like to find out what a lunar soil would consist of,
including particle sizes. I am sure it will work fine as a supporting
substrate, but some heavier metals, if present, could accumulate
into leaves and fruits rendering them inedible. The extent of this
could depend on thing like temperature, freeze-thaw cycles, particle
size, moisture content, pH, etc.

I shall be interested to see how your work progresses...
