This is NOT drip irrigation. This pic is of a sprinkler head. and will NOT work with gravity. They take a minimum of 12lbs pressure to even start to work. Nor is it compatible to a soaker system or a drip system. What do you want? A drip system or a soaker system or as in you pic a sprinkler system? A soaker system isn't a drip system. Here is a pic of an emitter in my garden. In this particular row they are spaced every 2 feet and they emit 1/2 gallon per hour. On other rows they are as close as 1 foot apart. Oh, and those little weeds are last years corn sprouts.

Garden already has a sprinkler system. As you know, not very effective. In addition to this challenge, I have expanded the growing area. I have that stair riser vertical planter and before long I'll have towers. The sprinkler has been turned off for the winter and I have been watering by hand as I re-introduce plants (all in containers for now).
What I want is to adapt the existing system, but that comes later. For now I need to figure out water delivery to the vertical stuff, I will use a makeshift olla system in the small raised bed, and as I expand I would like to use something rain barrel fed as well.
How is drip different from a soaker system?
