Characteristics of Vertical Grow Tower
Plants are grown in a vertical orientation.
Water enters the tower from the top of the tower and drains through various levels of plants, then water is collected at the bottom and returned to aquaponics system.
Towers can be made of PVC pipes, plastic or glass bottles, or other customized material.
Advantages of Vertical Grow Tower
Vertical grow towers are the ideal way to practice aquaponics in tight quarters, for example in an apartment window or a crowded greenhouse.
Towers can be made manually rotated, or disconnected to tend the plants.
Disadvantages of Vertical Grow Tower
Vertical towers, especially when using multiple towers, make it difficult for plants to receive adequate light.
Vertically stacked plants require careful management of water flow – where and how fast water enters the plants and drains from the plants.
Minimal water flow means solid waste can get stuck in plant roots, impeding plant growth and drainage. Vertical grow towers must have excellent mechanical filters to remove solid waste.
