One of the heralded benefits of hydroponic gardening is how it can alleviate poverty while simultaneously easing strains on the environment. Hydroponic gardening systems can be set up to recycle water and nutrients, greatly reducing the resources necessary to grow food.
Recycling hydroponic systems use as little as 10% of the water that traditional Hydroponics and Organics Experts requires, a tremendous benefit in areas entirely dependent on irrigation. Hydroponic gardening virtually eliminates the need for herbicides and pesticides, and hydroponic gardeners need only use about 1/4 the fertilizer that traditional gardeners require.
As the amount of arable land continues to decrease (over 10 million hectares per year are lost), another environmental benefit of hydroponic gardening will gain attention: Hydroponic gardens can produce the same yield as soil gardens in about 1/5 the space. And because artificially lit hydroponic gardens are not dependent on growing seasons, they can produce yields several times a year rather than just once. It has even been speculated that in decades to come, hydroponics will become a significant food source for over-populated urban regions, with people growing food on rooftops or in basements.
