This add-on piece works well for attaching two pieces of black tubing for the GreenStalk Spring Automatic Watering System. It's helpful if you need a longer piece of tubing than the 52" that the tubing comes in.

Coupler
I love that Greenstalks offers so many options to make my towers successful. The coupler will be instrumental in my watering setup.
