Great answers Lori!
Thanks.
My 3 and only troughs (so far) look OK but we haven't had really freezing temps YET!
I love them.
Each time I am in the kitchen I look through the window and try to figure out if the sempervivums in them got any bigger from previous look
I am a bit concerned abut their insulation as they are rather small and narrow (and the walls are also kinda narrow) - I wanted more space inside them.
Well, we'll see!
I am really wondering whether in my parts of world I'd be lucky enough to find some real stone troughs.
We used to be (and still are) mainly into agriculture, farming, and so on.
And I doubt people have shown any interest in the troughs.
Hmmm...
