Weedhound you can clone a clone indefinitely. That's how the 'elites' have been passed down, some as much as 20 years from the day the seed was popped.

Cloning a finishing plant is tough though. I'd re-veg first and THEN clone.

I have never once seen a successful clone of a finishing female. Not to say it can't be done though. I'd ask over at ICMag where the oldsters from Overgrow are still lurking.

Plus you're in DWC and I have NO CLUE how you'd go about re-vegging a DWC female in terms of differences in nute solution.

I'm going to start you a new thread for this. Where is Rhizome when ya need him?
