water cloner question

When using a water cloner how long should the roots be before i transplant into both soil and a DWC system?

Well I guess that depends on the individual,my clones get 2 weeks to root or they go to the big cloner in the sky.In 2 weeks 90% of mine have the fish bone structure in their roots.I plant mine in dwc (since I have a small cabinet)as soon as they get rooted and its time for the next batch to go in.I do not want any veg time because of my height restriction.
But as soon as you have some decent roots they are ready to plant,however you want to plant them,ie dwc or soil.
Good Luck and Happy Growing
