When we look around our planet, it might appear that life on the planet has an endless and plentiful supply of water. But if you observe closely, you will recognize that a little 1% of all the water on the earth is appropriate for human use. Astonishing, but true, 97% of the water is contained in seas, and is extremely salty for most farming & consumptive reasons. Our earth’s freshwater sources total to just 3% of what’s usable by human beings & of that, 2/3 are frozen in glaciers and ice caps.
As the populace grows worldwide, earth’s fresh-water supply isn’t just shrinking, but also becoming increasingly contaminated. Whilst many of you think nothing of paying more than a dollar for a small water bottle, just visualize what life will be when the quantity of water you consume in your home every-day is equally priced.
How hydroponic gardening help preserves water?
Producing a certain amount of food in a hydroponic method uses just five to 10% of the water the same quantity of food would require in an open field. How? Mainly because of the water employed to irrigate the vegetation in most of the soil-free gardens is recycled. Rather than irrigating too many bare lands in between crop lines, the water is accurately delivered to the root of the plant directly, which’s then amassed in a reservoir or tank to be used again at some point in the next watering cycle.
For your knowledge, it takes on average seventy-one gallons of water to generate a single pound of conventional field-grown lettuces. However, in hydroponic farming method, that same quantity of lettuce can be harvested using less than three gallons of water. Looking at it in a different way, you could cultivate more than twenty-three pounds of lettuce in a hydroponic garden with the equal amount of water it requires to produce 1 pound in the open field. However, the saving amount will vary from one crop to another, all plants grown through this system use less water in comparison with their field grown companions.
