Old school Hydro?

My uncle, who taught me how to grow, used to use a wick set up using 2L bottles as the pots, with the bottom cut off and turned upside down. He used what he called the Dutch method, 12/12 from clone, similar to SOG. Anyone out there using 2L and wicks? Is this still considered viable? I guess it would, since he always grew good shit. I haven't seen much in the way of wick set-ups on here.
