Growing hydro in water

A question from a fellow grower:

Im thinking about starting growing and looking for advice on hydrponic growing in water? Will be doing 4 plants in a 4x4 grow tent proper air flow, lights and air lines also. Just curious if its possible to get 8+ ounces from each plant with certain steps needed.

Good strains an nutes at least 3 feet tall maybe but if your new to it I wouldn’t waste good seeds to figure it out
