Made this up for our row of asparagus. I control flow with the valve at the tee, drilled 5/32" holes at each plant. Our garden has a slight slope so had to block up the lower end w/ bricks to keep the same flow from the holes. It will make watering a lot easier this summer w/ our low humidity. I'll put a hose washer w/ screen in the connector to keep out bugs and debris. W/ our hard water I probably should install a threaded cap on each end so I can drain it else mineral will build up inside and start plugging the holes.
