Cloning - Then timing of it all

[tAAka]

This is the first time I'll be creating my own clones for next year's grow. I've already got mothers and the strains I want but what I'm stumped on is figuring out when I should clone off of the mothers to have them ready for an outdoor grow by the end of May. I would like to have them good size, at least maybe a couple feet tall before the final transplant.

Just thought I'd stop and hear and see what you guys/gals had to say.

Thanks in advance for any help

About two weeks to root and 6 - 8 weeks to get them up to a decent size.
