Spinach (Spinacia oleracea) is a plant that is commonly known as green leaves, this plant is also a source of iron which is essential for the body and matures in a little more than a month. Tiny seeds germinate in a soil-less growing medium before being transferred to a water-based solution that provides all the nutrients they need to reach harvest size. Net pots inserted into the panels hold the spinach plants as they grow to maturity. With this method, we can enjoy fresh spinach any time of the year.
