Setting up automatic Drip irragation with 1" PVC & 0.5 GPH drippers

I have a question for any of you that have done this before.. I am setting up a drip irrigation system using 1" PVC that will include 10 6 outlet sites spaced evenly between the walking rows of my indoor garden. My question is as follows: Is it better to snake one long pvc thru the garden that has one capped end or can I use a couple "T" joints and have 3 capped ends?

Alternate Option C, closes back in on itself and would have no cap'd ends, possibly eliminating air bubbles http://i.imgur.com/qKL8A.png
