Instructions

Run the ¼ inch micro tubing drip line up through a drainage hole in the bottom of the window box. Reference this post, DIY Window Boxes, for the window boxes I used.
Once the drip line is up through the drainage hole, fill the window box with soil if it wasn't full already.
Add drip emitters (I used .5 GPH) every 3-4 inches across the window box. I like the drip emitters better than the spray emitters for a few reasons. They keep the water near the soil which reduces evaporation. They also won't spray your windows every time they come on.
You will add the drip emitters by attaching more dripline with T's, elbows, and straight connectors.
Once the emitters have been run along the top of the box, connect the end of the drip line that is coming out of the bottom of the window box to your main line.
We ran ours down along the bracket of the window box so you can't see it and then along the eaves of our house down to the spigot we were using. To keep it in place, we used these coaxial staples.
Test the drip line to make sure it is working once it is all hooked up.
You will need a pressure reducer, ¼-inch to ¾-inch hose adapter, and ¼-inch tubing stakes to keep the micro tubing in place anywhere it is in the soil.
