Gymnocalycium and some Notocactus/Parodias are fine in slight shade and under the bench is as good as anywhere for that.

Ian; Yes the E. knippelianus in my post above has been like that for 3 weeks now, just watered that side of the greenhouse tonight so maybe that might just give it the nudge

It is on a top shelf Ian.
The other Chamaelobivias are all in bud , but like yours not yet in flower ( pictures to follow if I see them early )

Now you are showing off Terry
A little bit like those GG I told you about in the Isle of man

Even old wrinkly is having a go.

Nearly there.

One of the smallest plants in the collection .

More Thelocactus in flower today.

Well it ended up 2 days after yours Mike.

It is an Harrisia for sure and with the stock being square in shape I think Phil is spot on with justbertii .
