I'd say it's not the best idea. You can grow larger plants by simply extending the veg period. It's not really practical in an indoor environment due to limitations of lighting, air circulation and various other things mentioned already. Bigger is not always better. Obviously, soil grown plants would benefit more from larger root space than hydroponics if you're not using chemical nutrients though. The buckets or pots generally used already provide ample room for either.
Providing the optimum environment from start to finish to suit the entire plant from the root zone to the tips will provide the best results.
Personally if I were to be growing in a large space I'd be doing my best to replicate or improve on the following style/setup.
