Psst. Carpet tiles.
harbour mould spores :0)

And bare concrete wouldn't?

A hard (ie, not earth) greenhouse floor should remain dry

Oh yeah, hands up those who floor stays dry? :-)

As far as I can see, there is little difference in potential moisture
retention between carpet tiles and bare concrete because in practice either
option can remain moist enough to retain one sort of "nasty" or another; it
just depends how liberal the user is in their application of water to the
plants.

So, that said, carpet tiles have a slight advantage as the are better
insulators underfoot.
