Produce such as broccoli, cabbage, celery, chard, cucumbers, eggplant, flowers, grapes, lettuce, melons, onions, peppers, pole beans, radishes, tomatoes, and strawberries have been grown hydroponically.
There are various techniques to hydroponic gardening. In water culture, the roots of the plants are held in a large waterproof tank. The plants are supported by mesh or string, and they get their food from the nutrient formula contained in the tank.
It was only in the 1840s when the principle was applied in modern agriculture. Researchers discovered that by developing a formula containing all the essential nutrients that plants need for growth– nitrogen, phosphorous, potassium, carbon dioxide, and hydrogen dioxide (H20)— the need for soil in growing them may be completely eliminated. Adopting this idea, a number of German botanists soon developed the basic nutrient formulas and growing techniques which are in use today.
The solutions for both systems are replenished periodically. And for lighting, a number of grow light devices are available used to automate lighting for plants.
With hydroponic gardening, the growing of crops requires as little as 10% as much land as regular farming, and less than 10% as much water. And sometimes, the water used may be even dramatically lessened further if the water is re-circulated.
Another attractive feature of hydroponic gardening is water economy. A large volume of hydroponic food can be grown rapidly in a small area.
One key advantage of hydroponic gardening is that the produce is less affected by insects thriving in soil or diseases caused by soil microorganisms. This, of course, means that farmers are less inclined to use insecticide to keep these pests away. The overall result therefore is that you have yourself crops that do not carry traces of insecticide, and can be picked ripe just before eating so preservatives are not required.
That’s what local growers say about hydroponic gardening. In a time when water and fertile lands to farm are scarce, soilless or hydroponic gardening is considered as a some kind of mana form heaven. Visit Hydroculture online shop for more details.
The possibility that plants could grow and survive without soil as the nutrient source was first described historically by Woodward in 1699, though the technique has been in practice since the time of the Hanging Gardens of Babylon.
These are used to support the roots f the plants. A solution containing all the essential nutrients required by the plant is pumped into the gravel from a holding tank. Click here – Smart Guy Hydroponic Supplies Store.
