Sub Irrigation Unit

We understand the struggle to keep the plants in your containers looking their best and keeping them watered properly. Our Sub Irrigation units allow you to install a water reservoir in your container to extend the time between watering, thereby reducing labor cost. These units will fit any container, not just ours. Spend time on other projects and less time watering your plants.
