I had to modify my Veritgrow Towers;
Water feeding the towers were damaging the foliage by keeping it too wet. I added a down cap, which also allows me to increase my water flow.
Water as it trickled down the towers would exit the towers at the back corners of the openings. Making a mess and not completely watering the bottom plants in the towers.
Adding water diverter cap...look at the tower in background, see the water mess.
Add "Plumbing Goop" in a U shape around the opening.
This step needs to be done before installing and planting.
A much cleaner look.
