Bubble Aeration was designed to aerate water by blowing air into the self-watering chamber, enhancing both root and soil health. Bubbles are created using a pump connected to a 1/4" hose that leads to a submerged tunnel for water aeration. This planter not only adds a beautiful touch to your home decor but also promotes plant health and helps prevent root rot. Additionally, the calming sound of the bubbling water creates a soothing atmosphere in any room. You can customize your planter by selecting up to two colors. It makes an excellent gift for any plant lover in your life.
