Closed irrigation systems are beneficial because they:

Closed irrigation systems are advantageous primarily because they allow for water recycling. This type of system reuses water rather than letting it go to waste, which is crucial for sustainable water management in greenhouse settings. In closed systems, the water that plants do not absorb is collected and recirculated, minimizing overall water usage and reducing the stress on water resources.

This recycling aspect also often involves capturing nutrients that the plants have not used, which can be beneficial for fertilization in future cycles. Thus, closed irrigation systems not only conserve water but also enhance nutrient efficiency, leading to healthier plant growth and reduced operational costs over time.

While installation costs can vary, closed irrigation systems typically involve complex infrastructure designs that may not inherently be less expensive compared to other methods. They also offer opportunities for automation, providing increased efficiency and monitoring capabilities that would not be possible in non-automated settings.
