The scientific study has said that the universe expands day by day. Literally it may mean the abiotic component but the actual fact is that it is shrinking. Actually speaking the population of man in this universe is increasing greatly. Man being the one to create problem in every aspect of the ecosystem always tries to find an alternative to compensate the loss. Greenhouse is one such beautiful finding made by man to grow plants effectively. Greenhouse, by the name it suggests that it is a house for growing the green. Many would be familiar of the phrase, “Grow green or else we ruin”. Greenhouse has given each and every human being a wonderful platform to cultivate plants.
Basic forms:
A greenhouse has two basic forms. One is attached greenhouse and other is a standalone greenhouse. In attached greenhouse the power supply is supplied from the house itself where as in case of a standalone greenhouse the power supply and all the other accessories has to be supplied separately. These types of standalone greenhouses can be made where there is sufficient space to have an individual green house. Greenhouse can be built using either plastics or by means of glass. The photo chromatic technique that can be employed in glass makes it preferable over plastics. The basic concept behind the photochromatization is nothing but SMA. SMA is the abbreviation of shape memory alloys. Shape memory alloys are also known as super alloys. These substances have the natural tendency to adjust to the situations that prevail and act accordingly.
Basic models:
The two basic models of greenhouse are cold frames and rack. Cold frames are set out in situations were there is less amount of space where as in case of racks ample space for setting of greenhouse is a must. The greenhouse cold frames constitute to the simplest and cheapest forms of greenhouse. By the name it suggests that it is suitable for growing of plants that requires cold climate. Cold frames are normally used for early sprouting of the seeds, growth of herbs and so on. It is so important for certain plants that the temperature within in the house doesn’t go beyond a particular temperature. So for cultivating those kinds of plants cold frames are very important. The glass panels adjust so as to allow only a small amount of sunlight to enter the greenhouse thereby preventing the damage of plants. Hence greenhouse cold frames are more preferred ones amongst the farmers.

In today’s world wherever you go the slogans depicted here and there is, go the green way, save tree save future and so on. The most popular phrase that everyone would have experienced is, “you aren’t the last human being to survive in this world”. This clearly sets out the message to save the future. So as an early wake up call, preparations for the future have to be made. Greenhouses have come at right time, which can be implemented in the future even if there is no space available to cultivate the plants.
Greenhouse concept:
What is this greenhouse concept? Greenhouse is nothing but kind of a house wherein plants can be cultivated. What makes it very special is that we can set a greenhouse in a place whichever is suitable for growing plants. Greenhouse is not a house, which is built by means of cement bricks etc. Greenhouse is a house, which is built using either by glass sheets or plastic sheets that are transparent. Glass sheets used are well-defined ones where as the plastic sheets are usually made of polyethylene or PMMR’S. Plastic sheets are strong and stiff longitudinally but not as strong as in transverse direction. So this paves the way for glass sheets as a common material to be employed in making of greenhouses. The small greenhouses uk made out of glass sheets are also known as glasshouses. Glasshouses can be interconnected to a computer and optimal parameters can be maintained so as to help the growth of plants. Greenhouses can be classified into two types: large greenhouse and small greenhouse. Small greenhouses are the common sight in United Kingdom. One can notice as many number of greenhouses if he turns out to a trip to United Kingdom. The very fact, which makes it most popular, is the space constraint, attracting as many no of people to own it. Greenhouses are used widely in UK for the cultivation of decorative flowers, vegetables and so on. Small greenhouses are employed by small farmers to gain more money from. Many ask what is the advantage of a greenhouse? The advantage of growing plants in a greenhouse is that crops can be cultivated in all climatic conditions thereby we can have an edge over the others who conventionally grow the plants. Based on the weather the conditions the greenhouse can be modified perfectly so as to help the plants to get the nutrients in a balanced proportion. Hence small greenhouse has attracted many in UK.

It is very easy to destroy the object, but creating the product is a tough process. In olden days we should not go for any growing process for plants. Basically most of the plants develop of grow very slowly. The growing nature of all parts resembles some curve. That curve is called S curve. In the initial stage of plant it grows very slowly compare to its life. At the middle stage the growth of the plant is constant. It should not deviate from the annual growth size during the middle stage. The final stage is considered as the peak stage. The growth of the plant is very rapid compare to the time period.
Need of Greenhouse
During its initial stage, it grows in very lesser rate. So to increase the growth rate in the initial stage, we are using the greenhouse. Usually all plants grows in a chill condition that’s why it grows very gradually. This gradual development of plant is healthy but not benefited to the owner. So the owners like to develop their plant rapidly. It should be achieved with the help of change in temperature principle. The cold atmosphere should be changed with the help of any other hot devices. The hot devices apply some heat air in the atmosphere and remove the cold air in the atmosphere. The principle of small greenhouse is very simple because, the hot air pushes the cold air out. So the environment turns in to warm. The warm condition is better suited for the plant. The warm condition enhances the plant growth cell and induces the cell to grow fast.
Price of small greenhouse
The cost of the small greenhouse lies in the range of $100 to $200. The space occupied by the small green house is also very little. So it is very easy to keep the greenhouse in the home. These are some of the advantages of small greenhouse. Before installing the greenhouse in your home you must know some of the important details about the small greenhouse. The principle is working only in certain conditions like low wind speed in the environment and hard climate. If the wind speed or velocity is too high then there is no meaning of implanting the greenhouse in your home. A normal wind velocity required for the greenhouse is 13 miles per hour. If the wind speed exceeds this limit then the quality of the greenhouse is drastically reduced. Likewise greenhouse depends on many minute factors, some guidance is required before buying the greenhouse trainer kit.

Every one of us will be having one hobby or the other. One among such a hobby is gardening. Advice is the freely available thing. When asking what to do in gardening each and everyone have their own thoughts. But when coming to gardening the real difficulty is faced in watering the plants. Everyone in the cold countries possesses their own greenhouse in their backyard. They won’t find time in watering the plants in them. Here are some simple methods to overcome the difficulty.
Scheduled Watering:
The plants in greenhouse require a timely watering for them to grow faster and better than the plants, which grow in a normal environment. So a proper schedule of watering them in timely basis should be followed to ensure them of good growth. The timely watering is alone not the sole criteria for the better growth in the greenhouse. The amount of watering is also need to be in the optimum level. This changes from plant to plant.
Straw-bale process research:
To provide the proper watering for the plants in the greenhouse research are on going in the field of usage of straw bales as a replacement for the conventional sand. The straw bale, which is recommended for this process, is the straw bale of the wheat plant. The straw bales are chosen because of their capability to retain air and moisture if they are in the wet condition. This is accompanied by their capability of slow decomposition rate and there by giving out the sufficient amount nutrients as and when required by them.
Automatic Watering System:
The automatic watering system is available in the market to provide water to the plants in a greenhouse. The automatic watering system is capable of providing the correct amount of water to the plant and in the correct time as and when required. The automatic watering system works in the principle of fire exhaust system in the buildings. This is a pneumatic operated valve, which carries water in them along with the control of microprocessors for the accurate control. They are also capable of maintaining the correct moisture level in the air too. It is very simple in design and very easy to install too. The cost of the watering system is in the high end when comparing it to install in a low level greenhouse. The marketers are ready to provide the customers with quality service. The installation of this watering system can define the quality.
The watering in any greenhouse is a tedious process along with the fact it consumes lot of time. So to avoid it methods are to be taken. The proper scheduling has to be done to water the plants. Then use of the straw bales can reduce the worry. There is automatic watering system available in the shop to make it easy for the maintainer.

In countries, which have severe cold weather prevailing it is difficult to grow plants. So in countries like those they mostly feed on animals for their eating. In cases of eating a vegetable, there a unique method followed in these countries to grow the vegetables. The use greenhouse in these regions is popular. Greenhouse is nothing but a closed room more often a building is meant where the whole building is made up glasses. The main purpose of the greenhouse is that it traps the sunlight falling in the region and never allows it to escape. So the room is warmer than the surroundings. This is usually done to grow the plants, which require a higher temperature than the surrounding temperature.
Items required for building a greenhouse:
The greenhouse is a structure, which is fully made up of glass. The main criteria for building such a one is that the fixtures made and the joints must be very strong. And the joints in the greenhouse must be aesthetic and the most appropriate material of selection is Aluminum. This is due to the fact that it is cheaper and the effectiveness of it in trapping the sunlight. Soil in the area must be most suited and since the plant that is to be grown is of the high temperature dependent plant it is advised to burn the soil with waste garden products before building.
Other Accessories:
Foundation kits:
In cases of plants, which do not grow in the soil condition of the particular place, it is grown with the soil from other areas. In such cases foundation kits are required. These foundation kits must fit stable and secure. In such cases the plastic foundation kits are most suited ones.
Roof vents:
In case of the greenhouse it is a closed room so aeration is of a big problem. So in the greenhouses roof vents are provided to solve this problem. It increases air circulation in a great amount.
Louvre window:
These types of window are placed in the rear side of the entrance. This is for two reasons. One is that it provides with increased aeration and the other is that it is for its aesthetic appeal.
Shade cloth and Shelves:
The weather is prone to change and in that situations shade cloth is required. It closes the entire greenhouse so by protecting the plants. For proper maintenance shelves are required. These are available as a set itself. They can be utilized for it.
Climate control:
The purpose of a climate controller is to provide the plants with proper temperature watering and air. This is advanced equipment seen in many greenhouses.
Greenhouse is a place to grow plants in cold weather. It is mainly made up of glass and aluminum fittings. The other accessories required are foundation kit, climate controller, roof vents, shade cloth and other things. From this it makes a complete set of greenhouse.

Greenhouse cultivation has become more common these days. The necessary awareness needed about the greenhouse has reached even the common man. The world as a whole is itself becoming a greenhouse. But still for improvement of the vegetable rate, which is going in the arithmetic improvement rate to meet the on going, geometric growth rate of the humans is very much required. Cultivation of vegetables and flowers in the greenhouse is a very painful task than growing it in the fields of their chance.
Difficulties faced in Greenhouse
The difficulties faced in a greenhouse are countless. The most major difficulties faced in the greenhouse are the factors consisting of temperature, air circulation and moisture. The temperature has to be correct for the plants to grow which is usually greater than the surrounding temperature and only in the most rare conditions it is lesser than the outside temperature. The air circulation has to be high as this is a closed atmosphere usually the available air in the room will be the minimal as possible. Then watering is a major problem faced by this group of plants, as it cannot be done as easily as it is done in the field. Where we can make paths and water can be sent to the respective plants.
Methods to overcome
The temperature is provided to the plants is usually carried out by the structure of the building itself. This has a inclined glasses which is capable of sending the sunlight inside but not allowing it to escape the way it came in. as by this fact it makes it trapped in so by fact causing the temperature of the building to be higher than the surrounding temperature. The temperature will be 70 degree Celsius if the atmospheric temperature is 0 degree Celsius. This can be achieved if proper design is made in the greenhouse. The air circulation is monitored when we use vents in the windows and a special type of window, which will take care of the needy, replaces the back door. And about the watering scheduled and proper watering has to be done in order to make the proper growth of the plants.
Automation
There is automation available for the optimization of the all the above-suggested things. You can optimize the watering system, which is a little modification of your fire exhaust system. This is capable of providing timely and correct water quantity. The other is the ventilation and temperature. These things are also controlled by the usage of climate controllers in the greenhouse.
In common greenhouse cultivation the problems faced and the methods to deal with it are mentioned here. The automation process that are available and the complementation principles that can be taken to improve the production are dealt with detail.

It’s a well a known fact that plants require sufficient amount of water to survive. With no chances of obtaining natural water sources for the plants placed in greenhouse, there is a great need to develop an artificial greenhouse irrigation to fulfill the water requirements of plants.
Why greenhouse irrigation?
Watering the plants using the water cans will solve a part of this problem but the efficiency of this method will be very less and also there is a great amount of hand work that is required to water plants. This method will only let the user to water plants only to a certain extent and the entire plant region cannot be covered using this method. There is also other option of using hose pipe to water the plants, but it will not be possible to water the targeted region. Hence there is a great demand for greenhouse irrigation that will greatly water all the areas in a uniform manner
Nowadays, it has become possible to water all the parts of the greenhouse in an automated manner using irrigation systems such as drip irrigation, sprinklers, misters and seep hoses. The watering operation can be operated by using parts such as controllers and sensors.
Automatic greenhouse irrigation
There are water timers that will be very significant in watering the plants in regular interval of time all through the day. There are many advantages that are associated with this system since it will let you to irrigate the greenhouse even during night time without your actual presence. This can also be of great importance in watering the plants when you go out from your home for a period of time.
There are also special instruments that will measure soil moisture and will water plants according to specific needs of plants, hence maintaining proper water requirements in the best possible manner.
Article Summary: Greenhouse irrigation is an essential part that should be given prime importance since these are the only source that provides water to the plant and prevent drying up of soil. There are many technologically advanced methods that will be providing many good solutions for water requirements of plan. There are also methods to automate this greenhouse irrigation process to maintain proper watering of plants.

When you start to feel that cucumbers is no longer attractive to grow in your greenhouse, and your friends no longer visit you in late summer to avoid the free tomatoes, you should really consider of growing melons.
Sow the melon seeds in your greenhouse between mid April and end of May. Sow them directly into 3 inch pots using standard potting soil.
Once the seedlings bear two true leaves, plant them out in a cold glasshouse inside growing bags. Better yet, plant them directly into well-prepared soil (with lots of organic matter) in your greenhouse. Composted grass clippings and straws are good ideas if your melons are trenched in using the double digging method.
Create some support for your melons. This may be a single line of string tied to the supports in the glasshouse roof, which is then secured in the ground with a peg next to the base of the melons. Or, you can always use a fan trellis.
As the melons start to grow, tie the strongest shoots to the support and pinch out the side shoots that grow from the main stems. When the stems reach the top of the support, pinch out the leading shoots. This trick will help your melons concentrate on bearing more and larger fruits.
Next key is watering. Water your melons well. Oh, they love plenty of water. The best way is using a drip irrigation system. Another is inserting a 3 inch pipe when planting those melons so that water can directly touch the roots. Remember that it should be constantly moist, not wet. So water your melons well, but never too much.
Once the flowers grow, take a small paint brush and lightly brush each flower to aid pollination. It is recommended to be done during mid-day since it is when the humidity is high. After 2 or 3 days remove the male flowers (note: a female flower has a melon-like growing at its bottom part).
Once the fruits grow, feed them with a liquid melon fertilizer (the one usually used to fertilize tomatoes as well) once a week.
When the fruits are as big as tennis balls, support them using string nets. As the summer passes by and the fruits reach full size, remove a few leaves to allow them ripen. Keep in mind that in the peak of the summer your greenhouse must be kept humid by watering the path early in the morning. Keep a bucket of water standing still inside it is a good trick, too.
Growing melons may be challenging, but the rewards are worth the efforts. The harvest can be enjoyed in various dishes. Tasty sweet!

Up until recently, fresh beans were grown on the bottom of columns in greenhouses as intermediate products in order to utilize space. However, for the last few years, fresh bean cultivation has been accomplished via the monoculture method. Fresh beans are not selective in soil and can thrive in sandy, sandy loam and humus soil. Bean growing is more difficult in salty soils.
Speaking of salt, irrigation water should not be salty either. Beans grow well under 6.1 – 7.4 pH degrees and are sensitive to cold. The minimum temperature required for seed germination is 50 F while the optimum temperature required is 68 F – 77 F during their development period and 64 – 68F during their flowering period. The temperature of the soil should be 64 F.
Fresh beans are not selective during the duration of daylight exposure. In greenhouses, fresh beans are grown in warm seasons (particulary in spring) by shadowing them. In this way, the temperature in a greenhouse is reduced during hot weather. On the other hand, there is no need for shadowing during the autumn season.
Beans do not like excessive humidity
Beans do not like excessive humidity during their flowering period since this causes the failure of their seed set. However, they require 60 – 70% water in the soil they are planted in. Irrigation should be done accordingly. There should not be much air current or a high level of humidity/temperature.
There are two cropping periods to consider when fresh beans are grown in a greenhouse — the fall season and the spring season. Cropping is done in the middle of September during the autumn and in the middle of December during the springtime.
The greenhouse in which the fresh beans are grown must be solarized or disinfected with chemicals during the summer, just as it is typically done for the other greenhouse products.
In addition, the ventilation windows of the greenhouse should be covered with a material which will allow air to enter but discourage insects from passing through (particularly during the fall season in order to protect against viruses). After tilling the soil for plantation, masuras are must be prepared for the double-row method with spacings of 45x20x15 inches.
One hour before drilling, soil should be left under warm chemical water in order to protect against diseases and harmful factors. 1-2 swollen seeds must be placed into each planting hole and covered with soil. Soil should not be humid during this process. Watering should not be done until the seeds are germinated and the cotyledon and first set of real leaves come up. Otherwise, seed decaying occurs due to excess water.
What to do, When the seedlings have 2 to 3 leaves ?
When the seedlings have 2 to 3 leaves, hoeing should be done. Trellising structures should be created by lacing twines on each row. This process should be done expeditiously, otherwise the plants will not grow effectively. Fresh beans have an innate twining quality. Once a bean plant clings to a trellis, it twines around the trellis and grows upright. There is no need for twisting it or pruning. Water should be given in small portions until the first formation of beans. When the beans begin to grow, they will need more water and thus the amount of water will increased along with the interval time (which will be reduced).
Which chemicals need to use ?
In the production of greenhouse beans, a controlled amount of organic fertilizers must be added to the soil. Prior to greenhouse solarization, 4-5 tons of stall fertilizer should be applied per thousand square meters.
Upon the first real irrigation, irrigation as well as fertilization should be applied during the growing period.
In one growing period, a total of 8-12 kg nitrogen (N), 10-12 kg phosphorus (P2O5) and 12-15 kg potassium (K2O) should be applied in pure form.
In fresh beans, the potential for self fertilization is 99%. Before the plants flower, the male and female organs are mature enough for fertilization and once the fertilization process is accomplished, flowers develop. Dry and hot weather during the fertilization period have a negative impact on the fruit set. The fruit (which is a bean) becomes small, it curls up, and then it turns yellow and falls off.
In fresh bean growing, beans should be harvested when they are mature and green. The fruit is a bean and there are seeds between the two carpel leaves. Harvesting should not be done before the seeds are filled and before the beans are in their place. There are three typical bean shapes: flat with curled ends, an open C or S letter.
In the event of diseases or pests, chemical control should be taken in accordance with the Technical Guidelines of Agricultural Control.

Peppers are an important vegetable in that they contain high calorie value, Vitamin C and plentiful mineral substances. Pepper cultivation covers a 15% area of total greenhouse vegetable cultivation. Protected pepper cultivation is generally done in a single crop during the spring seasons. As tomatoes suffer from a higher percentage of viruses during the fall season, spring is the preferred season to grow peppers. In greenhouses, registered varieties or varieties with production permits (as well as hybrid seeds) are used. The first requirement for success in pepper cultivation is to choose the variety most appropriate for the season and then set out to grow healthy and robust seedlings. Read the rest of this entry »
