I do it very similar. I run a T off the mainline and then another T at the plant. At the plant I do it alittle different. I use this
And make a circle with 5 of the emitters that go around the plant. I tried the emitters that you have, but I wound up with dry spots. I found that the circle gave me better coverage and the watering time was less because of the 5 emitters. Here is a picture, not a great one but you can kind of see what I am describing.
I added a fertilizer injector this year too. Nothing as fancy as yours, just one of the EZ-Flow ones.
I really like the drip irrigation as you can really customize it to your individual needs. Your video shows how easy it is too.
