Perhaps you do not have the room for a big garden in the ground. You may live in an apartment and only have a balcony. This would mean you need to grow your garden in containers. This is entirely possible and what is even better, is that you can grow an organic garden in containers. Most vegetables and flowers both do well in containers and you can keep your garden organic.
A hydroponic vegetable garden means it is grown from a water-based solution instead of soil. One of the reasons why most people choose to invest in hydroponic gardening is that in liquid, nutrients are easier to be absorbed by the plant roots compared to regular soil. Hydroponics is quite difficult to setup but because of its many advantages, it is becoming a bit popular among gardeners.
