Not sure what you mean about putting cardboard on top of the soil? Are you talking about extending the pots with cardboard wrapped around them?

You could try cake stacking, i.e. a few weeks into flower you use the same pot and fill about 1/3 with soil and place the rootball on top of that, then filling in the sides. IMO, you will run into trouble with just those 3 gals for the entire grow
