WTS's method (hmm... lol... I've seen it before) works well, except I would not let them sit in water- spray down the inside of the tray and dome so it's misty, but not an actual puddle.

I get roots showing in less than 2 weeks using that method.

I've also just started using these wicked blue 'ott lights' from Home DePOT (a different type of CFL) and they seem to work spectacularly.

Edit: 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.
