Just FYI... chances are VERY good that the seed in that purps was from a hermie pollination and will be female.
What I'd do is take clones when you have a large, healthy enough plant to give you a bunch of them, because you may not get good survival % on your first try. And leave enough cloneable shoots on the plant to go back and try again if you have a problem, since it sounds like this is a strain you'd really like to hold on to.
