Aero pot size

Building an aero garden and i m looking for advice on wht wouled be the best pot size to mamimize plants and yield in a SOG setup.

And do you think 8" is enough space betwen each pot??

Any help much appreciated.

peace

If you are going to do aero I suggest a 3" hole and a pool noodle. That is all I am planning on using. I might get the neoprene plugs instead but a big noodle is cheap and will last a while lol. As far a spacing goes with out knowing more info about your grow I cannot help.
