It depends on what you mean by efficient. Cost efficiency wise, normal land farming beats out hydroponics by a mile. And really, cost efficiency is one of the top things to consider when it comes to farming on a massive scale.

If that was the case, why isn’t every industrial farm doing it?
In part because traditional farms scale better than aeroponics or hydroponics. In part because farms don’t pay for the environmental damage they cause. Because of these two points, there is little incentive to industrialize aeroponics or hydroponics.
What is true right now is that traditional farms use more water, fertilizer, and space, cause more environmental damage, but require less labor. And the labor problem can be mitigated with robotics, if we’re willing to invest in that.
