The science of giving plants a favorable environment with the help pf a famed or inflated buildings covered with transparent or translucent material is known as "greenhouse technology." Greenhouse, sometimes known as a glasshouse, is a structure created to safeguard delicate or out-of-season plants from extreme cold or heat. Additionally, it shields plants from harmful weather elements like wind, precipitation, excessive radiation, insects, and illnesses. Around the plants, a perfect microclimate can be produced with greenhouses.

The modern greenhouse is typically a framed glass or plastic enclosure used to grow fruits, vegetables, flowers, and any other plants that need specialized temperature conditions. Growing plants and vegetables in a greenhouse ecosystem is known as greenhouse farming. By isolating plants in micro-ecosystems with the optimal circumstances for plants to grow healthy, robust, and attractive, greenhouse cultivation has helped farmers to boost their productivity while improving the quality of their output.

Functions of greenhouse:

There are various functions of greenhouse, which are as follows:

• The yield can be 10-12 times higher than non-greenhouse farming,
• Ideally suited for vegetables and flower production,
• Off-season production of vegetable crops,
• Efficient utilization of chemicals and pesticides,
• Modern techniques such as hydroponics, aeroponics and nutrient film techniques are possible only in greenhouse.

In order to successfully grow crops in a greenhouse, a large financial and managerial commitment is necessary. Profitability and cash flow are the two financial factors that any such business should take into account.  

Cost-benefit analysis:

There are two types of cost components involved in greenhouse farming.

1.Fixed cost component: Land cost, Construction materials, Irrigation system

2. Recurring cost component: Plantation, Cultivation, Maintenance, Storage, Packing, Transport

Cost analysis can be done by computation of Net present worth, Internal rate of return and Benefit cost ratio. Various researchers have shown the results that benefit- cost ratio is greater than unit indicating profitability of investment in greenhouses.

Do you know that you can make your garden anywhere by using grow bags? Well, the next future in gardening is here. The fact that you don't have an in-ground garden is no longer a problem. With grow bags, you can quickly transform your balcony or porch into a garden. Grow bags are exactly what they sound like: sizable, fabric-like bags that may be used to grow plants and vegetables. The bags can be filled with growing media. Although they are frequently composed of plastic, they can also be found in a variety of breathable materials.  These bags are tailor-made just for you. Following are the reasons why:

1.These bags can be used anywhere: The main reason grow bags are fantastic to use is that you can use them at any place. You may simply grow plants and veggies on a balcony if you rent an apartment or have one.

2. They are portable: Grow bags have the advantage of being portable because they are lighter than plastic pots and feature handles to make moving them around simple.

3. Healthier root systems are formed: Roots are less likely to circle, which is also known as root bound unlike in plastic pots, and are therefore more likely to build healthy root systems. This makes it simpler to prune the plants.

4. They regulate the temperature: Plastic pots can become warm when exposed to the sun. You don't have to be concerned about grow bags overheating because they are composed of permeable material. The grow bag's material is easily able to dissipate the extra heat.

5. They lessen the possibility of overwatering: Grow bags will expel any extra water through pores in the material, so you can't overwater them. This prevents the mold and fungus that might develop when a plant is overwatered in a plastic container.

6. And, they are reusable and affordable, too.

Grow bags can greatly simplify your work; they are, worth the expense. Think about trying grow bags; you'll be pleased with the outcomes.

In greenhouses, the crops are grown under the most optimum and consistent environmental circumstances. For the high yield, competent grower management should be used in conjunction with automated climate control in the operation. Automation in the greenhouse is a game-changer that helps greenhouses and nurseries accomplish more with fewer employees.

By integrating cutting-edge automation technology, a greenhouse can increase its efficiency. IoT smart greenhouses also called automated greenhouses, use a variety of technologies to monitor and control various greenhouse operations in real-time. Some greenhouses have even gone as far as to completely automate their operations.

Growers must adopt greenhouse automation systems for the following:

-Maintain a perfect environment of temperature and humidity,

-Better irrigation control,

-Improve the quality and yield of crops,

-Lower the cost of energy

NTS is a leading company in the Nepalese greenhouses ecosystem to adopt and develop automation technology. In NTS, we know the importance of counting on Automated systems for increasing the efficiency of the greenhouse. Therefore, we incorporate the Automation solutions in our projects, as per the requirements. We offer the right solutions to our customers of varied sizes, climates, crops and levels of investment.

Moreover, in NTS we have developed our own Climate Programmer JH-ECO CLIMA, designed to optimize the management of the internal climate of greenhouses. Our customers can optimize the climate of the greenhouse with a touchscreen.

Therefore, growers must quickly include user-friendly automated controls and remote monitoring systems to manage their commercial greenhouse effectively and effortlessly. Speak with our specialists if you want to learn how to set up a greenhouse automation system for your indoor farm.

A pioneer name in the ecology of Nepalese greenhouses is Nepal Thopa Sinchai Pvt. Ltd. It has been acknowledged for its determination to advance the adoption of innovative technologies for greenhouses.

Nepal Thopa Sinchai Pvt. Ltd. was founded with a campaign of TRUST IN AGRICULTURE through the provision of contemporary agricultural and smart irrigation services for the farmers and institutions working for the technology-based modern agriculture. At present, NTS has established itself as a one-stop shop for all agricultural inputs and services for agricultural development projects of any size, regardless of land, topography, soil, water, and agro-climatic conditions.

NTS now owns 12,000 square meters of industrial land and a warehouse with cutting-edge equipment for manufacturing greenhouses (automatic tooling, bridge cranes, folding and bending machines, shaping lines for the manufacture of channels and profiles, presses with automatic feeders, hydraulic tables, etc.). Also, NTS incorporate the Automation solutions in its projects, as per the requirements. NTS offer the right solutions to their customers of varied sizes, climates, crops and levels of investment. NTS promotes the use of drip irrigation system inside greenhouses, which is undoubtedly the most cost-effective way for the application of water and nutrients directly to the root zone of plants.

Hence, NTS has been a trailblazer in the Nepalese greenhouse ecology, for introducing modern and cost-effective technologies for the greenhouse growers.

Effective water and nutrient management not only encourages healthy plant development but also reduces costs and increases the sustainability of horticulture. It is understandable why greenhouse hobbyists and home gardeners are actively applying strategies aimed at improving efficiency.  Drip irrigation system is one of such technologies that can dramatically boost efficiency in several ways.

NTS promotes the use of drip irrigation system inside greenhouses, which is undoubtedly the most cost-effective way for the application of water and nutrients directly to the root zone of plants.

Description of NTS’s Drip Irrigation:

NTS’s Drip Irrigation involves dripping water onto the soil at very low rates (2-20 liters/hour) from a system of small diameter plastic pipes fitted with outlets called emitters or drippers. Water is applied close to plants so that only part of the soil in which the roots grow is wetted, unlike surface and sprinkler irrigation, which involves wetting the whole soil profile. With drip irrigation water, applications are more frequent (usually every 1-3 days) than with other methods and this provides a very favorable high moisture level in the soil which is favorable for plant growth and development.

Advantages:

• More crops can be grown from less water. 
• Maximum use of available water by the plants resulting maximum yield.
• Less weed growth and restricts population of potential hosts because of no water being available to weeds.
• High efficiency in the use of fertilizers.
• Low labor and relatively low operation cost.

Uses

• Mainly suitable for cultivation of vegetables; Tomato, Cauliflower, Cabbage, Chilly, Cucumber; fruits and flowers but also can be used for cereals, pulses, cotton and other closely spaced crops. 
• Can be used for irrigation both in open field and plastic tunnel also in slope area of mountain regions.
• It is also suitable for Kitchen Garden.

A drip irrigation system, when installed appropriately, will be 90% water-efficient and enable precise control. Install drip irrigation in your greenhouse to experience the multitude of benefits drip irrigation has to offer. NTS ensures to be your reliable partner through the process.

To provide favorable environment condition to the plants, greenhouse technique is used. To protect the plant from adverse climatic condition this technique seems more beneficial. Even during the winter, greenhouse stays warm inside thus helps in plant growth. The expections of sunlight highlight the importance of solar energy to agriculture. To improve continuously the productivity, profitability, sustainability of our major farming systems, we need a new and effective technology i.e. greenhouse technology. In order to optimize the productivity of plants, agriculture and horticulture seek to optimize the capture of solar energy. Specially those crops and plants which are not naturally suited to local climate , greenhouse convert solar energy to heat enabling year round production and growth of those crops. The problems of increasing atmospheric co2 concentration in atmosphere and the possible future climate changes result in low productivity, thus green house technology is considered as beneficial technique.

Being Nepal having tropical, sub tropical and temperate climate, many recent studies in Nepal are presented where greenhouse are combined with several systems to provide a favorable microclimate for crops under extreme tropical and sub tropical climates. Other applications such as greenhouse dryers and seawater green house desalination were also discussed. Greenhouse technology is becoming an increasingly indispensable and a viable solution for modern methods of crop production. Nepal being an agricultural country, thus also individual or families cannot meet their most basic need for food due to food insecurity. In remote mountain areas where the shortage of arable land and harsh climate, make it impossible to produce sufficient quantity of food throughout year.

The investigation in humla shows that using solar technology helps to improve food security. Solar greenhouse and dryers has also been used to meet the increasing food production. Depending upon the type of greenhouse, type of crop, environmental control facilities, the yield may be 10-12 times higher than that of outdoor cultivation. Extreme heat exposure can stress plant, stunt development and cause plant mortality during extreme summer , thus on the basis of utility the 2 types of greenhouse for active heating and for active cooling can be used. Based on shape, construction, covering material greenhouse technique can be used according to the purpose. Self employment for educated youth on farm can be increased after knowing the importance of greenhouse technology.

आवरणहरूः
हरितगृहहरू ढाक्ने आवरणहरू विशेष रूपमा सूर्यको विकिरणलाई सकेसम्म धेरै दिनको लागि डिजाइन गरिएको हुन्छ । सामान्य रूपमा तिनीहरूले न्यानोपना रोकेर राख्छन र पराबैंगनी विकिरणबाट बिग्रदैनन् । प्यानलहरू भारी कांच वा कुनै पनि सिंथेटिक सामग्रीहरूबाट बनेको हुन्छ जुन अधिकतम प्रकाश भित्र छिर्नलाई र न्यानोपना बचाउन मद्दत गर्न डिजाइन गरिएको हुन्छ । कांचले सूर्यको प्रकाश लगभग ९० प्रतिशत भित्र छिर्न अनुमति दिन्छ, न्यानोलाई कायम राख्न र पराबैंगनी प्रकाशलाई सोसेर राख्न मद्दत गर्दछ । पोलिथिन जुन सस्तो र  काँच भन्दा बलियो हुन्छ तर सूर्यको किरणहरू कम छिर्न दिन्छ ।
फ्लोरिङः
ग्रीनहाउसको भुंइमा उत्कृष्ट निकासको व्यबस्था हुनु आवश्यक छ । भुइँहरू कंक्रीट, ढुङ्गाको स्ल्याब, इट्टा, बालुवा वा फोहोरबाट पनि बनाउन सकिन्छ । बलौटे भुइँहरूले उत्कृष्ट निकास प्रदान गर्दछ र चट्टानहरूसंगको संयोजनमा झार बढ्नबाट जोगाउन प्रयोग गर्न सकिन्छ ।
हरितगृह भेन्टिलेशनः
सफल हरितगृहमा भेन्टिलेसन सबैभन्दा महत्त्वपूर्ण बिषेशताहरू मध्ये एक हो। यदि उचित भेन्टिलेसन छैन भने ग्रीनहाउस र त्यहाँका बिरुवाहरू समस्यामा पर्न सक्छन । भेन्टिलेसनको मुख्य उद्देश्य तापमानलाई आवस्यक स्तरमा नियमित गर्नु हो र हावाको आवागमन सुनिश्चित गर्नु हो साथै स्थिर हावा मन पराउने रोग अनुकुल वातावरणको निर्माणलाई रोक्नु हो । भेन्टिलेसनले प्रकाश संश्लेषण र बिरुवाको श्वासप्रश्वासको लागि ताजा हावाको आपूर्ति सुनिश्चित गर्दछ, र महत्त्वपूर्ण परागकणहरूलाई हरितगृह बालीमा पहुँच गर्न सक्षम बनाउन सक्छ । भेन्टिलेसन प्रायः हरितगृहको प्वालहरुबाट स्वचालित रूपमा नियन्त्रित र पंखाको प्रयोगद्वारा प्राप्त गर्न सकिन्छ।

हरितगृह तताउनेः

विशेष गरी चिसो हावापानीमा हरितगृहहरूको सञ्चालनको लागि तताउनु सबैभन्दा महत्वपूर्ण कार्यमध्ये एक हो । धेरैजसो हरितगृहहरूमा, जब पूरक ताप आवश्यक हुन्छ, प्राकृतिक ग्याँस वा विद्युतीय भट्टीहरू प्रयोग गरिन्छ । कम खर्चमा हरितगृह तताउने विधिहरू जसले कम ऊर्जा प्रयोग गरेर न्यानो दिन्छ जस्तै सौर्य ऊर्जा । यसले दिनको समयमा न्यानो जम्मा गरि चिसो अवधि (रातको समय ÷ जाडो) को समयमा तापक्रम बढाउन सहयोग गर्छ । पशुपञ्छी पनि हरितगृह तताउन प्रयोग गर्न सकिन्छ जस्तै हरितगृह भित्र कुखुराको खोर राख्दा कुखुराले उत्पन्न हुने तापले हरितगृह तताउछ जुन यसैपनि खेर गइरहेको हुन्छ । हरितगृह तताउनको लागि बिद्युतिय हिटरहरु पनि प्रयोग गरिन्छ÷ गर्न सकिन्छ ।
ग्रीनहाउसमा प्रयोग हुने स्वचालित सिंचाइ प्रणालीः

स्थान छनोट
ग्रीनहाउसको लागि राम्रो स्थान चयन गर्नु महत्वपूर्ण छ ।
ग्रीनहाउस बनाउने स्थान छनोट गर्दा ध्यान दिनुपर्ने कुराहरुः

1. सौर्य विकिरण – प्रकाश संश्लेषणका लागि बिरुवाहरूलाई सूर्यको किरण चाहिन्छ। बदल लागेको दिनमा बिरुवाहरूको प्रकाश संश्लेषण दर घट्छ । त्यसैले टमाटर, काक्रो, खुर्सानी, आदि जस्ता बालीहरुको उत्पादन बढ्दैन र उत्पादन गर्ने क्षमता कम घट्छ । तसर्थ, वर्षभर उच्च प्रकाश तीव्रता भएको क्षेत्र र स्थान छनोट गर्नुपर्छ ।
2. पानी – बिरुवाको उपयुक्त वृद्धिको लागि पानीको मात्रा र गुणस्तर महत्वपूर्ण छ। तसर्थ, पानिको उपयुक्त स्रोत भएको ठाँउ छनोट गर्नुपर्छ ।
3. उचाइ – उचाइले गर्मीको अधिकतम र जाडोको न्यूनतम तापक्रमलाई असर गर्छ । उपयुक्त उचाइ छनोट गर्नाले जाडोमा तताउने लागत र गर्मीमा चिस्याउने लागत कम हुनेछ।
4. सुक्ष्म–जलवायु
   -अक्षांश
   -पानीका ठूला क्षेत्रहरू – तापक्रमलाई मध्यम बनाउँछन् (जस्तै, तटीय क्षेत्रहरूमा भित्री क्षेत्रहरू भन्दा दिन÷रातको तापमानमा कम भिन्नता हुन्छ)।
   -रूखहरू, पहाडहरू वा अन्य अवरोधहरू – ग्रीनहाउसमा छायाँ पर्न सक्छ, विशेष गरी बिहान वा दिउँसोको समयमा। पहाडहरूले हावा र÷वा आँधीको ढाँचालाई पनि प्रभाव पार्न सक्छ
   -बादल र कुहिरो –निश्चित क्षेत्रहरू (उदाहरणका लागि, निश्चित पहाड श्रृंखलाहरूको ली साइडमा, वा तटीय क्षेत्रहरू नजिक) दिन वा वर्षको निश्चित समयमा बादल वा कुहिरो विकास हुन सक्छ जसले सम्भावित सूर्यको प्रकाशलाई कम गर्ने कुरालाइ ध्यान दिनुपर्छ ।
   -उच्च हावा चल्ने क्षेत्रहरू – उच्च हावाहरूले हरितगृहबाट तातो सोसेर लैजान सक्छ । त्यसैले भित्रको तापक्रम कायम राख्न आवश्यक ताप ऊर्जा बढाउन सक्छ । उच्च हावाले हरितगृहहरूलाई पनि संरचनात्मक क्षति पुर्याउन सक्छ।
   -धुलो÷बालुवा उडाउने – उच्च हावाले “धूलो वा बालुवा उठाउन“ सक्छ, विशेष गरी मरुभूमि क्षेत्रहरूमा, जसले केही हरितगृह ग्लेजिङ्गलाई क्षति पुर्याउन सक्छ।
5. कीटको दबाब – अवस्थित कृषि उत्पादन क्षेत्रहरूबाट टाढाको साइट छान्नुहोस् जसले खेतहरूमा कीराहरू बस्न सक्छ। चिन्ताजनक कीराहरूमा सेतो झिंगा, एफिड्स, स्पाइडर माइट्स र थ्रिप्स समावेश छन्।
6. स्तर र स्थिर जमीन – ग्रीनहाउस बस्ने जमीन हुनुपर्छः
7. सुबिधाहरू – सुबिधाहरूको उपलब्धतामा टेलिफोन सेवा, बिजुली, इन्धन आदि समावेश हुनुपर्छ।
8. सडकहरू – उत्पादन ढुवानी गर्न राम्रो सडकहरूमा पहुँच चाहिन्छ। ठूलो जनसङ्ख्या केन्द्र वा ब्रोकरेज सेन्टर नजिकको राम्रो सडकहरूले थोक र खुद्रा मार्केटिङलाई मद्दत गर्दछ।
9. ग्रीनहाउसको मोहडा
   -समान्यतया पूर्व–पश्चिम फर्केको ग्रीनहाउसमा जाडोमा बढी सूर्यको प्रकाश उपलब्ध हुन्छ।
   -ग्रीनहाउसहरूमा निकास उत्तर दक्षिण उन्मुख हुनुपर्छ।
   -समान्यतया ग्रीनहाउसको लम्बाइ हावाको दिशामा लम्बिएको हुनुपर्छ।
10. विस्तारको क्षमता – तपाईंले सुरुमा गरेको अनुमानभन्दा बढी जग्गा खरिद गर्नुहोस् ताकि तपाईंसँग आफ्नो सञ्चालन विस्तार गर्न सक्ने क्षमता होस । प्रारम्भिक हरितगृहहरू बनाउदा भविष्यको विस्तारमा जमिनको अधिकतम प्रयोग हुनेछ ।
11. श्रमको उपलब्धता – उत्पादकलाई मजदुरको रूपमा काम गर्न चाहने र राख्न योग्य जनशक्ति बनाउन बिभिनन व्यक्तिहरू चाहिन्छ । 
12.  व्यवस्थापकिय निवास – उत्पादक÷प्रबन्धक निवासहरू हरितगृहको नजिक हुनुपर्छ ताकि तिनीहरू आपतकालिन अवस्थामा छिट्टै हरितगृहमा जान सकून ।
13. सामुदायिक अवस्थाः ग्रीनहाउस निर्माणको लागि साइट छनोट गर्नु अघि उत्पादकले सम्भावित स्थानहरूको लागि सामुदायिक अवस्था प्राप्त गर्नुपर्छ । 
    -स्थान, उचाइ, इतिहास र मौसम।
    -जनसंख्या, रोजगार संरचना र श्रम शक्ति जानकारी
    -वृद्धि सूचकहरू, प्रमुख आर्थिक गतिविधिहरू र सम्पत्ति कर जानकारी
    -उपलब्ध गुणहरू, यातायात, सञ्चार र उपयोगिताहरू
    -सरकारी, चिकित्सा र शैक्षिक सेवाहरू
