When you water an area larger than you need to for one seedling, sprout or baby plant, you are over watering to being with.

Then if you only water the roots and not the whole container, the dryer soil will suck away the moisture from the soli around the roots so you haven't accomplihed a thing.

That is why you use a container suitable for the size of the plant root system. It is ok to 'anticipate' new growth, but be realistic.

Planting a seed or baby plant in a 5 gallon bucket because she will eventually be ready for it does not mean she is ready for it.

Can it be done?

Yes, of course.

Will it enable the plant to express her genetic potential?

No.

There is nothing at all wrong with transplanting. Done properly you can continue growth with only a slight 24 hour delay, but you will more than make up for that in the next 72 hours.

Putting a seedling in a big giant pot just so you wont have to transplant later on makes no sense at all.
