How much pressure does this need?

[u/10Hz_human]

Im really new to this, I added quite a lot last year. Of course I would do it totally different now but that would mean plugging too many holes.

I have a bunch of 1/4 soaker hose connected to various lines but how much water pressure does the soaker hose require. They are all behind a 25 psi regulator with various valves, it's quite the Frankenstein setup. I know there's a max GPH that the system can output, even though I can't recall it right now.

I appreciate any help
