Building on the success of its Pi Rack, Pi-Technics has developed a new compact growing system, the Pi Wall. The Pi Wall is a straight wall with a height of 2.18 meters with a capacity of 50 plants. Each plant has its own purpose-built, patented 3.5-liter container equipped with drainage holes and a basket to prevent blockages caused by the grow medium. The generous volume of these patented growing containers allows the plants to develop a strong root system while improving their ability to absorb nutrients. The built-in irrigation system waters each plant individually, so no need to punch holes in hoses.
