Lots of Growth - Mammillaria hahniana

If you go back through the blog to May 11th, you'll see what this plant looked like in this same pot.

It has now pretty much filled it so I figured I should up size the pot before the growing season is over.

If this same growth rate keeps up, I'll probably have to repot again in a year.  At that point I'll probably put it in a much larger pot to get it to show size.  Fingers crossed!
