If you start off in a smaller pot, it allows your root mass to grow out and build a really strong root ball. Then as you transplant into larger pots, it will keep doing the same thing. When you start off with clone or seed directly into a giant pot, this causes the roots to grow directly out to the side of the pot and then go down to the bottom, thus leaving all the soil from the base of the plant outwards toward the pot edge to have very little roots.
Main point, this will negatively affect your ladies. It's better for them to gradually change pot sizes, you will notice a bushier growth for sure.
