I live in Piracicaba, São Paulo, Brazil, about 100 miles north of Capricorn Tropic. I have been growing orchids since 76 but always liked cacti too. Four years ago I moved from an apartment in São Paulo to a house here and now I can have them. I planted about ten of them in the garden and that was all I had but, last November, I went to an orchid show in Joinville, SC, and there was this guy selling all sort of miniature cacti. I got 70 of them (well, probably all very ordinary I just found the names of a couple but with time will look for all). One died soon after, but so far I managed to keep the others alive. They are outside in the garden taking about full sun all day and water just when it rains. Here it rains about every ten days but during the winter sometimes we have forty days without a drop. Actually during the whole winter it rains only three or four times. Well, just wanted to say hi.

These are some of them:
looks like a nice varied collection. 
That's a nice bunch of C&S you have.
