There are many reasons for us to recycle. Simply put, hydroponics is the practice of growing plants using only water, nutrients, and a growing medium. Instead of soil, hydroponic gardeners use different types of growing media, like coconut coir, vermiculite, perlite, and more. In a nutshell, the idea behind hydroponics is to remove as many barriers as possible between a plant's roots and the water, oxygen, and nutrients it needs to grow and thrive. We can use recycled aluminium for almost everything in the construction of hydroponic garden.
Hydroponics offers people the ability to grow food in places where traditional agriculture simply isn't possible. Similarly, hydroponics is useful in dense urban areas, where land is at a premium. Finally, areas that don't receive consistent sunlight or warm weather can benefit from hydroponics. Hydroponics systems require only around 10 percent of the water that soil-based agriculture requires. This is due to the fact that hydroponic systems allow recycling and reuse of water and nutrient solutions, and the fact that no water is wasted. This perfectly fits the current theme of recycling and Hydroponics construction could be created almost entirely with secondary aluminium.
There are 6 types of hydroponics in total. I chose Wick Hydroponics - the wick system is the most simplistic type of hydroponics, requiring no electricity, pumps or aerators. Because soil isn’t needed, it could be a completely passive system made out of aluminium. Some people do like to place an aerator in the reservoir to induce more oxygen to the nutrient solution. In most system plants are placed in an absorbent grow medium like coco coir, vermiculite or perlite, with a nylon “wick” running from the plant root into a reservoir of nutrient solution. The wick system brings the nutrient rich water from the reservoir to the plant. Wick hydroponic systems work well for small plants and herbs, perfectly suited for creating an amazing garden at home.
