Help with auto irrigation setup

Planned on setting up a self watering system connected to a digital timer... so I planned on buying those Floraflex 3” halo drippers but I don’t care to get the other 50 things it requires(feels kinda pointless)

Planned on getting the box of 12x for $20 to use for my 12x 5.5 gallon air pots with 70/30 coco/perlite

Main question is, what sized pump (GPH) would I need to properly water my 12x pots?

Should I use all 1/2” tubes ? Or would 1/4” be okay and create enough pressure to evenly water everything ? Or should I star with 1/2” tubing and tap into those houses with 1/4” barbs and 1/4” hose(tubing)
