There are many plants used for hydroponics, some of them are much more profitable to grow on a hydroponic farm than on traditional soil, an example could be lettuce that needs a lot of water. Different other plants for hydroponics ca be found to be as productive as on classical methods, but you must realize that not any kind of crop can be grown on a hydroponic farm. This is why a good evaluation is required before replacing soil cultivation. Almost all the plants for hydroponics can be grown on soil terrain with similar results, problems appear when soil doesn't allow vegetable growing.
Do plants for hydroponics have special growth requirements?
Any plant regardless of the growing medium has certain needs to grow. Plus, there are also many elements that adjust the growing factors. Parameters like air, water, light are universal, plants for hydroponics respects these principles. The difference is that if a plant always has enough nutriments at its root, it won't concentrate in developing its root, and the entire energy will be focused on blooming and fruit giving. Thus plants for hydroponics are not chosen because they are resistant, but thanks to their capacity to produce a larger crop if they are properly fed on nutrients.
Another common factor that plants for hydroponics and plants in regular cultures have is the air movement. The air circulation will ensure that the plant receives the needed amount of carbon dioxide. The indoor hydroponic systems use all sorts of ventilation methods to replace the air inside, thus preserving the good health of the plants.
If you want to choose plants for hydroponics farming you should be well informed about each plant nutrient and mineral requirements, owing to the fact that the combination of the two is the most important element in the hydroponic system. In gardening or agriculture many minerals are not used in the classical fertilizers because the soil already has a sufficient quantity, hence a surplus won't be necessary.
In the hydroponic system you have to provide all the resources necessary to the plant or else you risk losing the crops or getting poor quality products. So keep in mind not to use soil fertilizers in a hydroponic environment. Plants for hydroponics systems must be treated with solutions that have a pH varying between five and six, also pay attention to the evolution of the plants in the various stages.
Further on plants choice for hydroponics
Plants for hydroponics are more exposed and fragile to variations in the amount of chemicals in the nutrient solution. Maybe in the classical method the soil helps diluting the chemicals avoiding the root being burned, but here you may risk exposing the plant roots directly to hostile action. So if you are not an expert try choosing a plant more resistant to chemical variations or use ready-made nutrient solutions.

Title: HYDROPONICS - A KEY TO FRESH VEGETABLES
|
|
Hydroponics gardens have over the years emerged as a great means of growing plants in homes. The technology is easy and simple. A plant needs soil only for the mineral nutrients it provides. If the mineral nutrients are acquired by the plants by any other medium then the need of the soil for the growth of the plants finishes. By hydroponics one can introduce the nutrients to the roots of the plants without making use of the soil. Hydroponics is a very effective way to grow fresh vegetables. With the help of hydroponics one can ensure than the vegetables grown are fresh and germless. Although the soil supplies all the mineral nutrients the plant requires to grown and thrive, it also has some disadvantages. The major disadvantage of the soil is the growing of weeds. Weeds are almost mandatory to grow. These weeds not only hamper the growth of the vegetables but also cause decline in quality and the taste of the vegetable. Since there is no soil involved while growing vegetables using Hydroponics Gardening technique, the risk that a vegetable faces from the weeds is cut down absolutely. The soil not only causes weeds but it is also responsible for many diseases that may affect the plant. These soil borne diseases hamper the growth of the plant. These diseases cause germs in the vegetables and even their quality also falls. By hydroponics one can ensure that there are no germs and diseases in the vegetables. This ensures the freshness of the vegetable. The risk of the vegetables being infected by them is cut down to zero. Cultivation of vegetables in soil requires a lot of hard work. There are a number of toilsome and laboring activities that a gardener has to do to guarantee unprecedented and unobstructed growth of the vegetables. It is not only a tiring job but also is a big time commitment. The farmer has to dig, pull out the weeds and rotate the crops. He also has to use pesticides so that the plants do not get infected with diseases. The use of the pesticide also has to be careful as excessive may cause the vegetable to become toxic and its quality may drop. A little bit of lax from the farmer may cause the quality and the freshness of the vegetable to drop substantially drop. However since hydroponics can be fully automated, this risk is also not there ensuring complete freshness of the vegetables.

Title: How does hydroponics works?
|
|
Hydroponics is a technique by which plants are grown without using soil. The soil acts as the nutrient reservoir for the plants. If the plants get nutrients from elsewhere then there is no need of soil for the plants to grow. Most of the times in hydroponics, introduction of minerals to the plants is done by cultivating plants in water that is rich in the nutrients needed by the plants to grow. Hydroponics can be done by using other mediums than water also. Hydroponics is relatively easy to do and also involves fewer hassles than growing plants in soil. Hydroponics has lots of advantages. One does not have to deal with weeds and soil borne insects. The plants also mature quite easily. Since there are no insects to be dealt with, the plants are disease free. The roots of a plant stretch a lot to acquire minerals from the soil. However, since by using hydroponics the minerals are available at the roots only, the cultivation of many plants can be done in less space. Owing to the fact that hydroponics is completely water based, it can be easily automated saving a lot of energy and time. A fully automated hydroponics system ensures that even if the farmer is not there, the plants get all the care they need. Hydroponics Gardening can be done indoors also. Grow lights are used to provide sufficient light to the plants. For hydroponics special fertilizer mixtures are required. A standard fertilizer would prove to be futile in the case of hydroponics. Hydroponic fertilizers are widely available in the market and one can find them anytime. One has to ensure that after dilution, these special fertilizers have a pH value between 5 to 6. One also has to be careful that the solution is changed in every two weeks. While changing the solution adequate water quantity should also be added because if the water in any case evaporates then the fertilizer would get thick and concentrated. If that happens then the roots would be at high risk of getting burned. The hydroponics system also needs some inert material that would provide support to the plant. These inert materials may include foam chips or clay pebbles. A pump is also required to ensure the water flow. The type of the pump depends up on the size of the reservoir. If these factors are kept in mind then hydroponics can produce excellent results with high yield and good quality of plants.

Title: An overview of Hydroponics Systems
|
|
Hydroponics gardening is a fantastic way to garden indoors. A soilless method of gardening, you can utilize a growing medium (or not) and feed the plants using a nutrient solution. Grow lights are used to ensure that plants receive adequate light so that photosynthesis occurs. There are many different hydroponics systems available, with different advantages to each. Learning about the different hydroponics systems will help you discover which ones might be best for you and your plants. In the static solution culture method, plants grow in glass or plastic containers that hold the plant nutrients. The plants are held above the liquid by resting on the lid of the container. A hole is cut in the lid to allow the roots through, so that they can reach the nutrient. Oxygen is also important to plant growth, so some form of aeration is needed in the solution. This is most often accomplished in home uses with an aquarium pump. The maintenance is fairly minimal, because you only need to refill or change the solution regularly. Instead of a lid, some gardeners use a sheet of thin plastic to hold the plants right on the surface of the liquid nutrient. With a hole cut in the plastic, this ensures that the roots are always in contact with the solution. This is an easy method for home gardeners to use. Aeroponics is technically not hydroponics, but it is related. Neither uses soil in which to grow plants. In aeroponics, however, plants grow in a mist or air environment. The plants are held in suspension on a support, and the roots are misted with nutrient solution at regular intervals. The advantage to this system is that it grows great plants while saving on energy and water. It usually takes less of both to grow the same number of plants aeroponically as it would hydroponically. Deep-water culture allows for very fast growth in plants, because, not unlike static solution culture, plants are suspended over nutrient solution, and the roots dangle in the solution. An aquarium air pump is used to oxygenate the solution, helping the plant roots to take in a great deal of oxygen, leading to quick growth. You can actually connect several plastic containers used for deep-water culture together, and recirculate the water into each container. The advantage of this system is the rapid growth you get out of the plants. All systems require adequate hydroponic lights. If hydroponics gardening is a new activity for you, you might find it easier to get grow light kits. These ensembles will have all of the necessary components to get your lighting system up and running quickly and easily. Grow lights make a big difference in how well your plants will grow, so be sure to invest in those that are suited to your plants and the environment in which you grow them.

Title: History of Hydroponics
|
|
Hydroponics is one way of growing plants without the help of any traditional methods. When it comes to gardening then one gets the idea that one need's an open space and proper tools that are used in gardening. Moreover a traditional gardening involves a lot of effort and money. However, when it comes to Hydroponics then each and every notion is changed. With Hydroponics Gardening you just need some plants that you want and a container where you can plant those. Hydroponics gardening is also known as Soiless Gardening. Therefore there are certain things which you need to take care for Hydroponics gardening. The history of Hydroponics goes back to the ancient civilizations who unknowingly applied the science of Hydroponics. Well at that time they were not aware of the fact that what they are employing now will be regarded as one of the finest forms of gardening in the future. Amongst the ancient civilizations it was the Incas, the Egyptians, the Aztecs and the Babylonians which incorporated this method of gardening. With hydroponics gardening they not only planted small plants but also grew crops. They had literally brought farming in their homes. Thus with the passage of time this technology which was invented by our ancestors got recognition just a few centuries back. It was during the 16th century when there was a need felt to protect the horticultural crops which were dying because of cold. Several techniques were devised but seldom any of them proved effective. Starting from bell jars, glass lanterns, hot beds and cold frames to low portable wooden frames that were covered with oiled paper of the 17th century, all these techniques were in vain. Various other techniques were also devised for fulfilling the same purpose. However, all of them were in vain. It was only after the post World War II period when the interest in Hydroponics was strengthened. With the advent of plastics various procedures of Hydroponics were simplified. Now the plastics were used for the glazing purposes of Greenhouses. Apart from that the plastics were also used in making the growing beds. Earlier these beds were made of concrete. As plastics facilitated drip irrigation so it was greatly used for Hydroponics gardening. Though during 1973 Hydroponics gardening had to take the back seat as the oil prices hiked. Due to this the cost of CEA heating and cooling also increased manifolds. Thus people started avoiding Hydroponics gardening. However after 20 years people again started taking interest in Hydroponics and started establishing CEA/Hydroponics systems again.

Title: CHOOSING GROWLIGHTS FOR HYDROPONICS GARDENING
|
|
Hydroponics gardening is a technique through which plants are cultivated without any need of soil. Studies tell that soil is only needed for its mineral contents by the plant. The mineral contents are absorbed by the plant when they are watered and the nutrients dissolve in the water. Hydroponics is a technique by which it is possible to provide the plants with the necessary nutrients artificially. Hydroponics Gardening is essentially not much different from any kind of indoor gardening when it comes to the use of grow lights. Grow lights are needed for proper synthesis of food as well as growing and reproduction in plants. The most often used grow light is the HID grow lights. High intensity discharge light come in many varieties which all have a digital ballast to keep check on the electricity passed through the lamp to ensure that it is working efficiently. Two kinds of HID grow lights are HPS grow lights and metal halide grow lights. Conjunctions are also used with a reflector which makes the light of the bulb purchased more intense. Metal halide grow lights are quite efficient and beneficial. Run with the help of argon gas, mercury, alumina, lots of metals and vapor HID grow light proves to be quite advantageous in magnifying the light produced by small bulbs. HPS grow lights also known as high pressure sodium lights are not much unlike in composition than the MH lights. HPS grow lights use sodium, mercury, xenon for functioning and they also require ballast to ensure smooth functioning and stabilize the whole process. Another very popular kind of grow light is the LED grow lights. These kinds of grow lights are relatively inexpensive and are ideal for hydroponics. They are light in weight and easy to maintain. They produce light in a number of colors making it quite effective in helping the plants growth. LED lights are not much different from the one's put on the Christmas trees. LED grow lights have a diode of whose function is similar to of a semi conductor. The light emitted is very bright and the lights are surrounded by reflectors. Reflectors magnify the light and once coupled with a lens it can be specifically used to direct light in any particular direction one may want. Every plant has a need of different type of grow light and one must determine the type of grow light by considering not only the cost but also the color spectrum needed by the plant to flourish.

Title: Hydroponics and Orchids
|
|
Growing and caring for orchids is a very pleasurable experience for any enthusiast. There is however an alternative to growing orchids the traditional way and that is with hydroponics. Hydroponics allows you to grow crops and plants without soil or compost as the roots of the plants are placed in a mineral nutrient solution. The Babylonians and Aztecs cultures grew plants without soil so technically they were using a form of hydroponics. Our technology and scientific knowledge has improved dramatically since the times of the Babylonians and Aztecs as well as our understanding of the benefits In their natural environment, plants absorb mineral nutrients from soil when these nutrients dissolve in water. The level of our understanding of the required nutrients has enabled us to artificially introduce them into the plants water supply and as a result the soil is no longer required. Please be aware that there is a difference between hydroponics and a soilless culture. Hydroponics is a type of soilless culture but other soilless cultures include sand and gravel. There are many advantages using hydroponics which can be applied to the care of orchids. • No soil – It should be obvious that you don’t need to purchase any soil. No soil means that soil borne diseases are no longer an issue which reduces the need for pesticides. • No weeding required • Watering – It is very difficult to under water an orchid but over watering is a very common problem. Hydroponics removes this headache and at the same time saves water. • Space – Less space is required with hydroponics. • Light – More of the plant is exposed to sunlight. Also, as more of the plant is exposed it is possible to see the roots so identification on any problems is easier. • It’s easy – The system is very easy to set up and once set up it requires very little maintenance. • Growth – The orchid is given the correct nutrients in the correct quantities which means more beautiful and healthy orchids can be grown. There are obviously many advantages which hydroponics provides. It won’t however solve all the problems faced by the orchid enthusiast. Greater flower yield isn’t always guaranteed and the costs can sometimes be higher than when grown in soil. Orchid enthusiasts should make an effort to at grow at least a few orchids using this method. They will be surprised at the ease of using hydroponics and it will only increase their knowledge and experience in the care of orchids. Nigel owns OrchidCareExpert, a website which contains lots of useful information if you wish to know more about orchid care.

Title: Hydroponics - Why Not Start Your Own Hydroponic Garden?
|
|
Hydroponics is the cultivation of plants in a nutrient rich solution rather than in soil. It involves growing plants inside without using real sunlight. The word hydroponics comes from two Greek words, meaning "water working".
If you enjoy gardening, but have limiting factors such as very little gardening space, problems with pests or unsuitable weather conditions, then hydroponics could be the answer for you. For many people, the thought of successfully gardening indoors all year around has only been a dream. However, with hydroponics this is possible.
General hydroponics is a hobby many people are picking up today. Hydroponics is simpler than what most people think, and is proven to have several advantages over regular soil gardening. The following are some of the many benefits of growing plants using hydroponics:
Less space is required, and plants can be grown closer together. Growing plants with hydroponics is possible almost anywhere.
Less water is required as there is no soil which soaks it up before it reaches your plant’s roots. Hydroponics is great in areas where there are water restrictions, as less water is lost to evaporation. When you water your regular garden plants, approximately 10% of the water actually makes it to the plants.
No pests or diseases. You don't have to worry about pest control, and because your plants are grown indoors, there are fewer problems with diseases such as mould and fungi.
Reduced maintenance time. Once your hydroponics system is set up, all you need to do is change the nutrient solution on a regular basis. This only takes a few minutes. There is no need for any weeding.
Types of plants grown with hydroponics:
Nearly all plants can be grown using hydroponics. The most common are vegetables such as tomatoes, lettuce, cucumbers, and peppers. Other plants include flowers and herbs.
Although hydroponics is possible for most plant species, a limiting factor is the amount of physical support required. If you are growing climbing plants, you will need to provide them with extra support.
Hydroponics supplies:
Hydroponics gardening supplies can be found at most good gardening stores nowadays. Before visiting your local store, it is a good idea to do some research online first, so you know what you need. You can also purchase supplies online.
Your grow lights are one of the most important factors for hydroponics gardening. Hydroponics stores sell individual parts as well as complete growing systems. These will include the hydroponics and lighting systems, fans, and timers, etc.
In conclusion, a hydroponics system will initially take a bit of time and effort to set up, but in the end it will be well worth it.

Title: Hydroponics Faq: Getting Started In Hydroponics
|
|
*What is hydroponics? Hydroponics is commonly referred to as "the cultivation of plants in water." However, study shows that various media can support the growth of the plant, so the definition was broadened to "the cultivation of plants without soil." * What plants can be grown hydroponically? Theoretically, most plants can be grown hydroponically, but in practice, some are easier to grow than others. Among the easier ones are lettuce, basil, mint, tomatoes and peppers. Plants like watermelon, squash and strawberries are harder to grow. * What are the advantages of hydroponics? The most apparent advantage of hydroponics is its manageability in controlling the plant-growing environment. Other benefits of hydroponics are: - Less water used - Lower labor costs - No need for expensive soil fertilizer - Certainty of plant production * What nutrients do hydroponic plants require? Nutrients are needed by the hydroponic plants in order to grow and promote production. Basic nutrients consist of the following: Water - There should be an adequate amount of water for optimum growth. Oxygen - It is necessary to bubble air around the roots of the plants to supply sufficient oxygen. Carbon Dioxide - It is required along with hydrogen for producing carbohydrates. Minerals - Including potassium, nitrogen, calcium, magnesium and sulphate. All of these nutrients must be present for a hydroponic plant to grow. * What different growing media can be used in hydroponics? The different growing media used in hydroponics are: Expanded Clay - enables nutrients to be controlled by the water Rockwool - made from basalt rock Coco Coir - made from the husk of the coconut Perlite - very lightweight volcanic rock Vermiculite - often referred as light pebbles Oasis root cubes - suitable for large-scale nutrient film growers * How much time does a hydroponic garden require? Starting a hydroponic garden requires time commitment and dedication. It needs plenty of time if you want to make sure that the plants are in good condition at all times. At first, it will also take you longer to mix the nutrient solution. From time to time, it is necessary that you check on the pests or diseases that might attack your plants. The time involved in setting up your own hydroponic garden also depends on how big and complex it is, as well as the type of plants you decide to grow. * What equipment do I need to start growing hydroponic plants? Necessary equipment should be prepared before you can start hydroponics. The equipment can be purchased at most nurseries or garden centers. You will need: - Gallon buckets - A small pump - Drip emitters, hose and connectors - Rockwool (absorbent type) - Geolite, lava rock or stone pebbles With this equipment, you can proceed with your hydroponics planting project.

Title: Do Your Plants Need Hydroponics?
|
|
All plants need the correct conditions in order to grow to their full potential. Plants grown using hydroponics systems are no exception to this basic rule. Like their soil grown cousins they need sufficient light of the correct wavelengths, a suitable temperature, an adequate water supply, enough oxygen, mineral nutrients and support for their structures.
Sufficient light of the correct wavelengths, used by the plant at the growth stage it has reached, is essential for its survival. Plants use lots of light, at least 8 to 12 hours each day, in order to make carbohydrates from CO2 and water. Chlorophyll, the green color in plants, absorbs the sunlight and uses its energy to synthesize these carbohydrates. This process is known as photosynthesis and is the basis for sustaining life in all plants. Because animals and humans get their food by eating plants, it can also be said to be the source of our life.
Artificial lighting is generally a poor substitute for sunshine, because most indoor lights provide insufficient intensity to produce a mature crop. High intensity lamps such as high-pressure sodium lamps can provide more than 1,000 foot-candles of light. The hydroponics gardener can use these lamps very successfully in areas where sunlight is inadequate. The fixtures and lamps, however, are usually too expensive to be viable for a small commercial operation.
It is important to allow adequate spacing between plants as this will ensure that each plant receives sufficient light in the grow-room. For example, tomato plants, pruned to a single stem, should be planted so as to give 4 square feet per plant, while European seedless cucumbers should be allowed 7 to 9 square feet and seeded cucumbers about 7 square feet. Lettuce plants need to be spaced 7 to 9 inches apart within the row and 9 inches between rows. Most other vegetables and flowers should be grown at the same spacing as recommended for a conventional garden.
A suitable temperature is required for the plant to grow normally. Temperatures that are too high or too low will give rise to abnormal development and reduced production. Summer vegetables and most flowers grow best between 60degrees and 80degrees F, while winter vegetables like spinach and lettuce prefer temperatures of between 50degrees and 70degrees F.
An adequate water supply is not normally a problem when using a hydroponics system, since the basis of hydroponics is the supply of water containing nutrients in solution. Having said this however, there are some systems which can give rise to inadequate watering, with the consequent detrimental results to your plants. Ebb and flow systems which are not checked on a regular enough basis, can run short of nutrient in their supply tanks, as can continuous flow systems. Most, if not all, automated hydroponics systems can have disasters if they are not monitored closely. A blocked or burst pipe, or a pump failing can result in lack of nutrient flow, which, coupled with the intense lighting and the correct ambient temperature in the grow-room, will result in dry roots and severe damage to, or even the death of, your plants.
Oxygen is a basic requirement of most living things. Plants need oxygen for respiration, so that they can take up water and nutrient. In soil systems enough oxygen is usually available, but plant roots growing in water will quickly use up the supply of dissolved oxygen. This can damage or even kill the plant unless additional air is provided. A common method of aerating the nutrient is to bubble air through the solution. Continuous flow and aeroponic systems do not usually need supplementary oxygen.
Mineral Nutrients are needed by most green plants. They must absorb certain minerals through their roots in order to survive. In conventional horticulture these minerals are supplied by the soil and by the addition of fertilizers such as manure and compost. Nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur are needed in large quantities, whilst the micro-nutrients, iron, manganese, boron, zinc, copper, molybdenum, and chlorine are also needed, but only in very small amounts.
Support is normally provided by the soil that surrounds the growing plant. A plant grown using hydroponics however needs to be artificially supported. This is usually done with string or stakes. It is possible to buy inexpensive automatic string reels to support your plants as they grow. This cuts out the tedious task of having to keep re-adjusting the strings on fast growing plants.
