Open vs. Closed Hydroponic Systems
An open hydroponic system is where plants are grown in nutrient solutions without soil. The nutrient solution flows past the roots before draining away. These systems require close monitoring to maintain the nutrient balance. However they are inexpensive and simple.
In closed hydroponic systems, the nutrient solution is recycled back to a reservoir after passing the roots. These systems use less water and nutrients. But root diseases can spread more easily between plants sharing the same reservoir.
Most commercial hydroponic farms use open systems despite the higher nutrient usage. This is due to their lower cost and ease of operation. Closed systems require careful monitoring and maintenance to prevent disease and salt buildup.
Advantages of Hydroponics
Hydroponics offers advantages over soil growing: faster growth, higher yields and quality. But the setup costs are greater, especially for indoor growing. Outdoor hydroponic farms can work well with attention to climate, seasons, and pest control.
