bicflikr, you will still have to be certain to follow re-veggin protocols.
Don't allow Nitrogen deficiency to take hold later in flower. This means continue to use some fish emulsion along with your grow fert, and don't flush for the week leading up to harvest.
HArvest only the buds, leaving as much green leaf on the plant as possible. Even leave small popcorn buds on.
Give a dose of SuperThrive or ThriveAlive, and put under 24/0 of blue flourescent light.
Do not over water during this period.
Re-vegging should take about 1-2 months.

This does not make it a perennial, though; you've ARTIFICIALLY returned her to a vegetative state.
