Healthy, nutritious and tasty food keeps us going each day. But when we sit with that bowl of greens and other colourful salads thinking we are eating healthy food, are we really sure it’s healthy? Hydroponics is a sure way to grow food without pesticide. Growing food hydroponically allows us to have full control over what we are ingesting. The yield from this technique is also much higher than that from conventional farming and may very well have the solution to the food shortage problem on earth. For example: Conventional agricultural output of potatoes per acre is 13,400-22,400 lb whereas the Hydroponic equivalent per hectare is an astounding 140,000 lb.
It’s shocking and scary that when we purchase and consume produce from the supermarket, we are ingesting some very harmful chemicals like urea, excessive sulphur, chlorides and other chemicals along as well. These are widely used chemical fertilizers and pesticides. It’s also misleading to read “organic” on the label because growers may claim they didn’t spray the crops with these chemicals. But do they have control over underwater tables and air that has the runoff and chemical aerosol from a much polluted environment?
What then will help us get clean, nutritious food on our table which does not have any poisonous traces on it? The science of Hydroponics offers an innovative solution. Hydroponics allows us to grow food without pesticide. The Merriam Webster dictionary defines hydroponics as: the growing of plants in nutrient solutions with or without an inert medium (as soil) to provide mechanical support. Simply put, Hydroponics is the science of growing plants in mineral and nutrient enriched water without soil. Sounds strange? Soil isn’t what a growing plant feeds on. Instead, it has some select nutrients that plants require to synthesize their food. The mechanical support of soil can well be substituted by coco coir, wood fibre, gravel, sand and various other media. Hydroponics can be used for large scale agriculture and right in your homes as well if you plan to have a little garden for yourself. This technique has several other advantages like less labor and garden maintenance, pests and diseases are easily avoided as the climate can be controlled, plants are free from weeds and will thus grow healthy ensuring that we get good, wholesome and food without pesticide on our table.
Not only will this help us overcome food shortage problems, but also address the problem of forest cover being converted into agricultural land. It may help us save the flora and fauna of the earth which is nearing extinction. The water usage for Hydroponics is as little as 1/20th of the water required for conventional agriculture, thus reducing the strain on earth water resources as well.
Choosing Hydroponics to grow food without pesticide may also be an answer to the problem of global warming and climate change. We can then ensure that our future generations will inherit an earth where their eyes can still feast on the verdant green of forests and when they enjoy a meal, they can be sure that no nasty chemical is making way into their bodies.
