Why isit better to build a rootball in a small pot then transplant to a bigger pot, instead of straight away planting your seed/seedling into a big pot?
Another reason is that you better utilize your soil. Roots grow in a stait line until they reach the side an botom of your container. Then they follow the side and botomm searching for more soil so that most of the roots end up on the side of your pots. the soil in between transplants is mostly void of roots and the soil is basically waisted.
Repotting plants makes them grow faster, and faster, and faster. .
Tube dude says it right. The roots grow sideways first, then hit the side and turn down. A small plant in a big pot will send roots down to the bottom first without 'exploring' any of the soilmix above. Those few roots at the bottom are now prone to waterlogging and lack of oxygen. I would estimate that about 50% of the problems I see people having with soilmix/container culture originate with a mismatched pot to plant ratio and the watering problems that result. Repotting plants makes them grow faster, and faster, and faster. A small plant in a big pot won't grow as fast as a plant repotted many times. Of course, that assumes your technique is good enough that there is no shock and you can put the plants directly back under the light with no delay. If you're able to get the rootball out in one piece (no holes or ripping the ball) the plant will grow as if nothing happened.
