I'm going to ask this here to see if I can get a better response. I'm building a 6' tall by 8" wide strawberry planter that I would like to hook up to an automatic watering timer.

I have the timer and need ideas on what to run down the center of this vertical planter to water from top to bottom as evenly as possible. I've thought about drip hoses, soaker hoses, pvc pipe with drilled holes..ect Any ideas would be great!

Here it is, found in Pinterest.
