Germination time

I'm trying to plan the timing of my next grow. How long of a time is it between when I first start to germinate a seed (in rockwool) and when it's ready to put in a 5-gallon bucket? I usually plant clones, so I guess I'm basically asking how long it takes to go from a seed to the size of a rooted clone.

 

Wow that's a lot quicker than I expected. Cool, thanks for the reply.
