great ideal keeping her as mother plant, remove all the larger fan leaves every 3-4 weeks to stunt the growth, only feed her once a week (1/2 strenth fish mix nutes ) and take the cutting couple of days after feeding, I would keep cut the plant back (topping) so you keep her short and get her really bushy ( more clones)
take some cutting and flower the mother plant off outside , ( should be able to keep her short and very bushy till she goes out side, could use a screen as support when she first starts perflower
this plant would be massive and you would pull lbs off her
Its all about 100's of short level shoots in a very large pot before you put the plant outside
good luck
