Oh...I have the Isola soil *and* Isola water. But mutation...I've never messed with that. I was hoping for a solution to get the citrus ball cactus (and eventually the fourpetal maple) the old-fashioned way by simple breeding.

common seeds I have:

citrus maranta
jalapa maranta
bluestar ball cactus
jalapa maple
fabled maranta
citrus astera
fragrant astera
jalapa astera
citrus reptans
fourpetal reptans
bluestar reptans
rosaceae grass
