Repotting. New technique to try?

No one likes a rootbound plant. The health just deteriorates.
I know if repotting is done correctly there should be minimal stress.

I have been thinking... as a "repotting regime" - Start the seedlings in really small pots(I'm talking pots that would contain only two fists full of soil), let them become rootbound in the little pots...

Move them into slightly bigger pots, so they grow out again.

Let them get rootbound in those, then move them into a considerably bigger pot just before flowering, so that the root growth will not be interupted during flower.

How do you guys think this will work?

Can this kind of thing be done several times?

Would this kind of strategy be useful with making the ultimate use of root space? (I have heard that roots will stretch outwards, leaving unused space in the middle of the root mass, and then begin to curl once they encounter a barrier)

I am doing my first grow and it has been a great success until this rootbound experience of mine, and I didn't give it enough thought before now. SO! Share thy wisdom fellow growthers!
