Now that we have a better understanding of the natural growing process, we can see that hydroponic is all about enriching water with the very same nutritive salts found in nature. It’s about creating and maintaining a “nutrient solution” that is perfectly balanced for your plants. Most hydroponic systems contain the nutrient solution in a closed system. This helps protect it from evaporation and from discharging into our environment as dose the runoff from exposed, fertilized soil. This conservative approach to water management makes hydroponics the method of choice in drought-stricken areas worldwide, and as a result, it is rapidly becoming known as “Earth Friendly Gardening”
