I can understand soil needs some kind of checks but pumice can be used in the building industry and for other things which have nothing to do with horticulture, it's all very strange.

Cider, why do you need a phyto certificate for inert materials?

Yes you do.

Could be Psocoptera Booklouse?

If the individual heads stay small then it looks like it could be Haworthia 'Cassytha' of unknown origin.

Tonight at 7 o'clock in the UK.

It has been nice seeing photos of other peoples versions of this plant. It does look like it would make a good 'wall or rockery' plant but I think it may be to large for most greenhouses, I mean you could get 20x Turbinicarpus in that space

Sedum palmeri from Rayones in Mexico survived a hard winter and seems to be doing well in a very shallow stone sink with a half inch of gritty soil and a lot of gravel.

It's interesting to note that what we do consider to be 'our' plants have been turning up with more regularity at Alpine Garden Society shows. Mammillarias, Rebutias, small Opuntioids and medusa type Euphorbias are excepted on the show bench.

If they run off with your money you don't even know which country they are in.
