Each Tropf Blumat can control 5 of these distribution drippers and saturate a 40" length - either in a row or around a large plant. So with this set you can set up 10 mini systems like that. The caps go on the ends of the last distribution dripper to stop the water flow.

If your plants and conditions are the same, you can also put one Tropf Blumat in the first pot with one distribution dripper and one or two in each put after that.
