The thing not to forget and what is also important to consider in all irrigation is the water flow. As the pressure reducer keeps it down to 1 bar then pressure is regulated. What you need is at least 8 litres a minute flow rate. And as mentioned if you’re going to push the distance above 20 meters then using 1/2" main pipe would help in some cases and sparing off. As you’re only using 3 drippers the exit points shouldn’t make that much of a difference. Adjustable drippers are a very good choice. It’s important to make sure that you deliver enough water to the plants without wasting any.
