Seaweed cultivation is the farming of various types of seaweed in ocean waters or controlled environments. This process involves planting seaweed seeds on ropes or nets, which are then submerged in the water. Seaweed grows quickly, often doubling in size within weeks, making it a sustainable and efficient crop. Farmers harvest seaweed by cutting it from the ropes or nets, ensuring that the plants can regrow. Cultivated seaweed is used in many products, including food, cosmetics, and fertilizers. Additionally, seaweed farming can help improve water quality and provide habitats for marine life.
