root loss = smaller pots?

[ryrycochinco]

I was resently repotting some of my spring bloomers and noticed some root lose. This usually happens because when they bloom i take them out of the greenhouse and display them around the house. Naturally they dry out a bit and loss some roots. Anyway do putting the plants in smaller pots so its more snug for the roots increase root growth?. I done this in the past and I think it works, but maybe the same would happen in a bigger pot?
