This is what I use as well, it works great and is easy to customize. I get my stuff at HDepot...I think it's called DRIP or something. The little bags of hose ends are in yellow a blue bags sorted in labeled boxes. What is great about is that I can move the watering zones around.
The line also has a timer that I paid about $45 dollars for and it takes care of the watering during the week. I'll get out there and hand-water/fert on Sunday to get a good look at everything.
It is one of the few things about orchids that I didn't spend a ton of money on. !
