Make a drip ring type feed line. Gram per watt would be a guess, strain lights, environment, just too many things but I would expect a very good yield.
That is a concern I have too with a true Aeroponic system , plugged nozzles is part of the maintenance. Thats part of why I run the simple DWC with lots and lots of air, the plants will live in the mist and drink a bucket dry so I never change the soup. Kind of a ghetto aero. My plants love it when the buckets get low.
I am doing scrog with LED and I am getting just under 1 g / W and I hadn't grown in 20 years before starting back up in May. really depends on the LED and what the diode spectrum and ratios are. EDIT:... and i am in soil so you should be able to get a better yield after a few runs.
