Aeroponics, misting the netcups, just the roots or both?

Hi,

my aero system is top feed and the nozzles are pointing down and are spraying the water downwards.

My roots are nearly touching the bottom of the grow chamber now (12" deep). The nozzles are adjustable vertically but currently they are at the highest position spraying just the netcups.

I could adjust them to spray just the roots so the netcups and clay pellets stay dry. Or I could adjust every second sprayer to spray the roots as most netcups are surrounded by 4 sprayers.

So two sprayers could spray the netcup and two the roots.

Which is the preferred method to spray the water?

Thanks

agree pics, you wouldn't want to let any of the roots dry out, especially the ones closest to the crown of the plant
