These days, there are less and less fertile farm lands to grow crops in. But contrary to what you may think, this doesn’t pose such a huge dilemma for our growers. Why? You might ask. The answer lies in hydroponic grow systems.
Ever since the Biblical times - the time of Babylon to be precise - we have already come up with a means to grow plants without need of soil. How else do you think the Hanging Gardens of Babylon remained hanging up there and still managed to wow people all over the ancient world? Simple: The Babylonians used a form of hydroponic grow system to keep the plants’ nutrient and water supply running.
Today, we don’t have the Hanging Gardens anymore. But what we do have are miniature gardens that survive even indoors in a small apartment space. These “gardens” are no more than water tanks powered with an aeration system and a steady supply of nutrients through a formulaic solution. This is hydroponics for you, more popular known as “soilless gardening.”
Below are the different types of hydroponic grow systems currently in use:
The Wick Hydroponic Grow System
The Wick system is by far the simplest of hydroponic grow systems. Its main components are:
* Grow tray
* Growing medium
* Wick
* Air pump
* Air stone
* Reservoir
The wick system is a passive system, which means that there are no moving parts. The nutrient solution is placed inside a reservoir, which is really nothing more than a water tank or an old aquarium you no longer use. The growing medium can be anything from perlite, vermiculite, pro-mix or even coconut fiber.
In order to draw the nutrient solution into the growing medium where the plants are, a piece of straw or tube called a wick is used. The air pump is placed just outside the water tank and is used to pump air into the air stone, which produces bubbles containing oxygen necessary for the plant roots to survive.
Because of its inherent simplicity, this hydroponic grow system is the commonest type of system used by home gardeners. You can even fashion your own wick system from old containers and aquarium devices so you don’t need to purchase anything besides the nutrient solution.
The biggest drawback of this hydroponic grow system, however, is that large plants or those that use large amounts of water may use up the nutrient solution faster than the wick can supply it.
Nutrient Film Technique Hydroponic Grow System
Often abbreviated to N.F.T., this hydroponic grow system is the kind of system most people think of when they think about hydroponics. N.F.T. systems are typically composed of the following:
* Grow tray (tube)
* Nutrient pump
* Reservoir
* Air stone
* Air pump
This hydroponic grow system has a constant flow of nutrient solution so no timer for the submersible pump is required. The growing tray, usually a tube, is pumped full of nutrient solution, which flows over the roots of the plants, and then drains back into the reservoir.
Usually, this hydroponic grow system does not use growing medium other than air. This thus saves you the expense of replacing the growing medium after every crop. Normally, the plant is supported in a small plastic basket with the roots dangling into the nutrient solution.

Indoor Hydroponic Systems
In fact, you may not even need to purchase a lot of materials for you to start building your own system. Hydroponic Grow Systems Depending on the size of your planned indoor hydroponic system and the interior space you have available, you can even use that old aquarium tank you have as a tank to contain the nutrient solution. Besides the tank or the reservoir, most indoor hydroponic systems consist of a growing tray or tube, a timer, and a pump. It is also necessary to provide a source of light, which in this case where sunlight may not always be available, should be a special lighting device designed specifically for growing plants. You can find these in any garden shop anywhere. The air pump is responsible for keeping oxygen levels in the nutrient water adequate for the plant roots to survive. Usually, an air stone, a kind of porous stone that produces air bubbles, is used...

... the nutrient solution. An air pump outside the whole tank keeps the air supply running, by sending air to the air stone which bubbles the nutrient solution and supplies oxygen to the roots of the plants. If you are growing leaf lettuce, water culture is the hydroponic system of choice. Lettuce is a fast growing and water loving plant, making it an ideal choice for this type of hydroponic system. Very few plants other than lettuce will do well in this type of system. Ebb and Flow Sometimes called the flood and drain, the ebb and flow hydroponic system works by temporarily flooding the grow trail with nutrient solution and then draining the solution back into the reservoir. This action is normally done with a submerged pump that is connected to a timer. When the timer turns the pump on, nutrient solution is pumped into the grow tray. When the timer shuts the pump off, the nutrient solution flows back into the reservoir. The timer is set to come on several...

... of them mere variations of the more basic types. Below are four hydroponic growing systems commonly used today. Water Culture or Aqua Culture The word hydroponics comes from the Greek word hydros meaning "water" and ponics meaning "method." But research soon dispelled the belief that plants can only grow in either water or soil for scientists discovered that there are other Hydroponic Grow Systems growing media available. Still, when people hear about hydroponics, most of them would probably think of water culture as the hydroponic growing system used. On a small scale, water culture method of hydroponic growing system is the simplest form to set up. This system allows plant roots to be totally immersed in nutrient solution. The only trouble with this hydroponic growing system...

... cabbage, celery, chard, cucumbers, eggplant, flowers, grapes, lettuce, melons, onions, peppers, pole beans, radishes, strawberries, and tomatoes have been grown hydroponically. Another attractive feature of hydroponic gardening is water economy. In Hydroponic Grow Systems arid areas, where precious water must be re-circulated, hydroponic systems may help improve harvest yields. A large volume of hydroponic food can be grown rapidly in a small area. In fact, it has been reported that four heads of lettuce can be raised in the same amount of space required to grown one head of field lettuce. 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. Another form of...

... worry about. In addition, diseases caused by these pests are minimized, if not eliminated completely. It has also been found that properly grown hydroponic plants are healthier and more vigorous. This is because in hydroponic gardening, no soil is used, which means that the nutrients are more readily available to Hydroponic Grow Systems the plant. Thus, the plants can mature faster, yielding an earlier harvest of vegetable and flower crops. The big advantage of hydroponic gardening is the ability to automate the entire system with a timer.

With general hydroponics, all the necessary growth elements are readily available to the plant. Thus, plants can mature faster, yielding an earlier harvest of vegetable and flower crops. Hydroponic gardens use less space since the roots do not have to spread out in search of food and water. Because of this, many home gardeners have found general hydroponics an ideal method Hydroponic Grow Systems for growing plants right indoors. Greenhouse space is also better used. But more than its space-saving benefits, the biggest advantage to general hydroponics is the ability to...
