I have a 4' by 4' raised bed, where each 12"x12" square contains 16 pea or bean plants. I am wondering what is a good way to set up the drip system to properly water the plants when they're that closely spaced. I have soaker dripline with emitters spaced at 6", but I'm not sure whether running this through the center of a square will reach all the plants in that square. Should I have it double back so it runs first between the first 2 1x4 columns of plants, turns, and then comes back between the 3rd and 4th columns of plants?

There are about 3 inches horizontally and vertically between each plant, so 6" emitter spacing is twice the plant spacing.

Or is soaker dripline the wrong thing to use? Recommendations? Thanks!
