So Many Ways To Grow: Underground Greenhouses, Aquaponics, Hydroponics, Vertical Farming, And More!

There are so many innovative ways that one can approach growing food, aside from just conventional farming methods. From underground greenhouses to aquaponics, hydroponics, organic farming and more. There are many ways that you can grow a lot of produce in a small amount of space.

Hydroponics is just one method that allows you to grow at home without any soil and there are a number of hydroponics kits that are now being sold in various areas, as more people look to grow their own food at home with ease and efficiency.

Another approach, being used in Newark at one of the world's largest vertical farms is able to grow without any soil, sunlight, or water. The produce is grown in a reusable cloth that has been made up of recycled plastic bottles and they are fed a nutrient-rich mist for food.

Another vertical farm in japan is able to grow 12,000 lettuces a day with just LED lights!

A post by The Guardian just this week posed the question as to whether or not organic farming methods could feed the world, asserting that such methods promotes more profit, yield, and benefit for the environment. It discussed a recent study that was conducted which looked at roughly 40 years of scientific studies that compared the long-term benefits and prospects of organic versus conventional farming and they determined that organic farming was superior.

Underground greenhouses! These things are just awesome and relatively simple to construct. The underground greenhouse allows for year-ground growing and they can be constructed in a large variety of different geographical locations, which is great for folks growing in places that perhaps might get too cold during certain months for growing.

Aquaponics is another approach that uses fish in order to establish a soil-less environment for your plants to grow. This approach combines vegetable farming and fish farming approaches. It is said that this approach could greatly help to reduce world hunger if utilized because it offers the grower more yield that they will receive in a shorter amount of time. The approach will also require less input and result in less waste than conventional methods.

Given the innovation and ability for growth within the agriculture space, should we really buy into the fears that we get told again and again that we don't have enough food or ability to feed the world's population?
