When you consider 268 linear feet that's 4' wide OR 1072 square feet total coverage, I really think wicking is about as labor intensive as a drip emitter system.( Though I live in what is considered desert we do freeze in wintertime) and the plan is to remove the ( above ground ? ) portion of the Sys in the late fall and reconnect in the spring while the poly feed line will stay buried.
As to the materials I asked about, the Soakerhose is the largest o.d. ( outside diameter ) I could find available on the market, And the Netafim is kinda like a polypipe hose with outlets ( read; holes ) evenly spaced along its length. Both have an available filtration package so hard water will not be a problem.
Also, because of the width of these beds, I must run a minnimum of 2 lateral lines to ensure targeted saturation per bed.
Nonetheless I'm grateful and appreciate your time and suggestions.
Thank you
