Why Should You Grow Plants Without Soil?
Hydroponics, the seemingly slight change in how we make food (i.e. ignoring the soil) is really groundbreaking as it enables farmers to harvest food anywhere in the world at any time of year and to net higher yields with fewer resources.
Grow Everywhere
Growing seasons and regions are in great flux right now as temperatures change and growing conditions change along with them. Even in "natural conditions, there are plenty of areas where the land is not suitable for farming.
Right now most of the vegetables you've come across in a supermarket have been brought in from abroad and losing nutritious value along the way.
Hydroponics can be used to build hyper-local food systems – Hydroponic farms can be set up in any town and area so you can have ultra-fresh produce! And when you cultivate hydroponically, you don't have to hit a seasonal break or face crop failure due to bad weather.
Greater Yield
Plants that are raised in well-managed hydroponic systems live a long life. Since roots are bathed in all the nutrients they require, plants spend more time growing up and less time and energy growing vast root systems looking for food.
Growing rates differ depending on the type of system and level of treatment, but hydro-plants can grow up to 25% faster than the same soil-grown plants, with increased crop yields.
Use of Fewer Resources
Hydroponic systems typically consume less water than conventional soil-based systems. This is because closed networks are not prone to the same rates of evaporation.
In addition, the water used in hydroponic systems can be treated, repopulated with nutrients, and fed directly to plants again, meaning the water is continuously being recycled instead of lost!
Pesticides and other potentially hazardous compounds are not required as hydro crops are safe from certain pests and plant diseases occurring outdoors in soil-based farms.
Simple problem-solving
How many times have you gone out to your garden and seen one of your plants flourish while its next-door neighbor is drooping? In this case, it is almost difficult to know which aspect is adversely affecting your bad plant. Is that a pest problem? Are the nutrients in the soil different?
In a hydroponic device, you know precisely what environments the plants are growing under. As such you can conveniently separate the variables and experiment! If you've discovered the right recipe for light, pH equilibrium, and nutrients, you can repeat success without constantly reaching curveballs.
