What is a poly house?
A poly house refers to a sub set of green houses that is specifically made with polythene films which are used as covering. This design is much more cost effective as compared to a green house as it uses a less expensive material compared to glass. The structure and functions are however extremely similar to a green house and its main object is to create an artificial micro environment that is conducive and promotes plant growth.

Average poly house profits for various crops for a one-acre construction:

1. Turmeric- 14 lakh INR
2. Tomato- 12 lakh INR
3. Cucumber- 9 lakh INR
4. Ginger- 15 lakh INR

Why are there poly house subsidies in India?
The climate patters in India are frequently changing and are often unpredictable. This causes uncertainty among farmers and leads to a reduction in the output levels that can ideally be achieved. Inventions like the poly house and green house were formed based on this and help in solving a major problem that is faced by farmers in India. Poly house cultivation is being promoted by the state governments in India as it is the largest private sector contributing to the economic activity in the country. There subsidies make the input cost for farmers extremely low and affordable which promotes them to learn and adapt to poly house cultivation which will show higher results than traditional farming in the long run.
The Horticulture board of a state of NABARD branch in the state helps in assisting farmers with the process of availing subsidies for the construction. The national Horticulture Mission under MIDH guidelines provide subsidies to farmers in various arenas.

Farmers can claim up to 80 percent subsidies in the following states:
• Polyhouse construction subsidy in Karnataka
• Polyhouse construction subsidy in Tamil Nadu
• Polyhouse construction subsidy in Telangana
• Polyhouse construction subsidy in Maharashtra
• Polyhouse construction subsidy in Kerala
• Polyhouse construction subsidy in Uttar Pradesh
• Polyhouse construction subsidy in Gujrat
• Polyhouse construction subsidy in Haryana
• Polyhouse construction subsidy in Tripura
• Polyhouse construction subsidy in Nagaland

A 50 percent subsidy is provided for the project cost and farmers can avail the same to establish the poly house structure. Apart from this, every state has its own scheme where an additional subsidy between 15 percent to 40 percent can be availed. This makes the total available subsidy range between 50 percent and 90 percent.
In Himachal Pradesh the state government has declared an 85 percent subsidy to farmers who are interested in constructing poly houses. This subsidy will boost the development in the agriculture field drastically. If the poly house is damaged due to any natural calamity, then 50 percent subsidies will be provided to replace the polythene sheets after 3 to 5 years post instillation.
If technical standards are met, non-impaneled vendors can also build poly houses. The government has introduced a Mukhiya Mantri Nutan Poly house project which aims to increase the land covered under poly house faming to 8.35 lakh hectors and increase the land area under micro irrigation to 8.20 lakh hectors.

What is poly house farming?
A poly house refers to an enclosed structure made out of a metal/ wooden frame with a covering of polythene films that are used to artificially create a micro environment that will promote plant growth by creating a conducive climate for the same. Poly house farming is gaining immense popularity in India as it has not only previously shown its advantages but is also massively promoted by the government.
Poly house farming is a suitable example of precision farming where the quality of the crops harvested is based on optimum usage of resources. It helps in cultivating a larger variety of crops which may be considered as exotic plants in a location or may simply be out of season for that time period. The output produce is also of high quality as the protected structure of a poly house ensures that there are no unwanted pest attacks, pathogen or insect invasions etc. with an automated and externally controlled supply of water, fertilizer and humidity the produce is of utmost quality.
Poly house farming has various advantages as the crops are grown in a controlled environment. There is lesser chance of crop damage due to over heating or cold shocks. It reduces the cropping period and overall increases the yield five to ten times.

What is vertical farming?
Vertical farming refers to a process where crops are grown in vertically stacked layers instead of a single flat surface. This method of farming was introduced in 1999 in order to combat the problem of increasing population and food demand in comparison to a fixed land area suitable for cultivation to meet the food demand. This faming helps in maintaining and even increasing the produce by reducing the land wasted for producing the same.
This type of farming used certain technology to maintain and monitor the temperature, humidity, gases and light inside the stacks.

Advantages of vertical farming:
• Reduction in agricultural run-off
• Year-round crop production
• No dependency on external natural climate
• No weather-related crop failures
• Reduction in operating and maintenance costs
• Sustainable faming method
• Larger produce quantity in same land area
• Easy to set up and use
• Cost effective and pocket friendly
• Scope for automation and remote controlling
• Reduction in occupational hazards
• Reduction in labor and energy efficient

Techniques of vertical farming:

1. Hydroponics: This refers to a process where crops are cultivated without the use of soil. Nutrient enriched water is used as a substitute and there are various types of hydroponic farming’s tat can be adapted based on the specific need of the plant.
2. Aeroponics: This refers to an advanced version of hydroponics where nutrient induced mists are used instead of water. There is no growing medium and farmers need to simply place the seeds in foam placed in pots.
3. Aquaponics: This refers to a system similar to hydroponics where aquaculture is integrated into the faming process. Farmers produce fish and aquatic animals for consumption in an artificial environment and the excrement from the same is used as fertilizer for the plants creating an artificial environment extremely similar to the natural eco systems.

What is a greenhouse?
A green house refers to a building designed for the protection and growth of plants that may not be currently in season or are exquisite in nature to a particular location. A green house helps in protecting the plants against excessive cold and heat as well as pests and pathogens. The origins of a green house structure can be dated back to the 17th century where ordinary bricks were used with a small portion of ventilation space with a few added means of heating.
With a progression in technology and development in the agricultural landscape the green house structures have become much more sophisticated with the use of glass, wood or metal frameworks. Later, the green house technology advanced into automation and developed from mere environment control to creating an artificial environment that is extremely conducive for plant growth.
There are various types and sizes of green houses. It can be commonly stated that large green houses are more actively used for agriculture, horticulture and botanical science study and research while smaller greenhouses can be used for domestic planting by hobbyist, home gardeners and collectors.
A greenhouse traps heat and light hence creating a warm temperature for the air, water and nutrients. Naturally, the light of the sun is allowed to flow into the greenhouse. If the heat provided by this thermal energy is more than what is required, the cooling systems that are installed are activated. However, if this thermal energy is not enough even after being trapped and reflected using aluminum panel, the artificial heating systems that are installed can be activated. Both these options help in creating the perfect temperature for the plants to grown in.

What is a poly house?
A polyhouse refers to an enclosed structure that helps in promoting plant growth by creating an artificial environment extremely similar to the environment of the natural growth habitat of the particular plants that are cultivated in them. A polyhouse is a subset of the green house concept where specifically a polythene sheet is used as a covering material within which crops can be grown are in either a partial or fully controlled and automated environment.
Since this method of farming using only polythene sheets and gives the desired output very similar to a glass structure of green houses, it is more commonly used and available in India. The materials of making for a polyhouse are much lower as compared to a greenhouse and is hence preferred by most farmers.
However, the durability and strength of a polyhouse is relatively lower than a green house, which give the green house an advantage of having a longer life and sustainability that polyhouses. Green houses can be entirely automated while there a certain restriction for the same in a poly house.
Choosing if a poly house or green house is better for the farmer is based on various factors such a budget, maintenance expenditure, locality, labor costs etc. It is best to seek professional guidance about choosing the right mode of farming based on these external factors.

What is Poly house farming?
Poly house farming refers to the process of cultivating plants in a controlled environment providing the right quantity of heat, cold, humidity, air temperature, nutrients etc. to the plants in order to promote conducive growth. The primary objective of a polyhouse is to create an artificial environment that will boost plant growth and ensure the output is of optimum standards.

Crops suitable for poly house farming:
• Vegetables: Capsicum, Cabbage, Radish, Chili, Tomato, Bitter gourd etc.
• Fruits: Papaya, Strawberry, Blueberries etc.
• Flowers: Marigold, Orchids, Rose, Carnation

How to start polyhouse farming?
There are various steps that need to be completed before poly house farming can be actively practiced by a farmer. India is among the top rankers for protected cultivation with 10.10m ha actively practicing the same. While poly house cultivation has paved the way for off season fruits and flowers to be grown comfortably, there are certain concepts to be kept in mind for a successful yield:

1. Site selection: This refers to the process of ensuring that a suitable location is selected for poly house farming and the construction process can be conveniently completed by procuring the inputs, ensuring cost effective labor is available and a good transport facility is in place. It should be kept in mind that the poly house should not be very far away from the market place as this will add to farmers transport cost of the produce and also lower the freshness and quality of the produce.
2. Water source: Similar to every form of cultivation, water plays a major role in ensuring optimum plant growth. It is important to have a clean water source near the location so that the quality and quantity of water used can be planned and improvised based on the need of the plants.
3. Growing medium: It is essential to plan before hand how the crops will be raised in the appropriate growing medium. There are various options available to a farmer such as compost mix with sand, coir-pith etc. this will further determine if the plants will be grown in a pot culture of be planted directly into the fertile land depending on the type of crop.
4. Electric energy source: Similar to water availability, it is extremely important to have an uninterrupted source of electricity as this will be used to power any heating, cooling and ventilation systems that may be installed. This is important to control the environment which is the primary objective of a poly house.
5. Maintenance: post construction, during the course of usage it is important to maintain the poly house with regular cleaning cycles, repairs to the polyethene film if necessary and other vents. This maintenance will maintain the quality of the poly house and maintain the efficiency for the plants.

While polyhouse farming is a cost effective and budget friendly process, it is also highly dependent on various external factors during the initial stages. Installing the right kind of poly house will ensure that there are no unwanted costs that may lead to dissatisfaction among farmers.

Why is greenhouse automation important?
Greenhouse automation refers to a process where an added external control system is used to monitor and measure certain specific aspects of a greenhouse. A greenhouse provides plants with a high degree of protection against unwanted pests and pathogens, adverse weather conditions and external factors that disrupt plant growth. The external factors directly affect how the conditions inside the greenhouse should be adjusted and maintained to provide the exact micro climate for plant growth.
There are optimum conditions in which plants thrive and creating that right environment can be tricky due to the various environmental variables like light, thermal energy, wind, humidity, rain, perspiration etc.

Advantages of greenhouse automation?
There are innumerable benefits to automating a greenhouse that can be summarized as follows:

1. Creating conducive environments- Crops often need an exact environment to thrive in. automating a greenhouse can help in easily creating the exact micro environment that will not on maintain but also boost the plant growth process. This will help in avoiding unwanted influences that may directly jeopardize the crop yield.
2. Reduction in labor costs- Automating a greenhouse directly reduces the amount of manual work to be practiced which reduces labor cost and gives the workers a chance to focus on other areas of importance. This is extremely beneficial if farmers are trying to expand the greenhouse or add new crops to the same.
3. Irrigation without disturbance- Automating a greenhouse will ensure that an accurate amount of water is provided to the crops at the right time. Problems relating to over watering and under watering are tackled by automation as a good schedule is created and stuck to ensure there are no inconsistencies. Automation also gives farmers to adjust any fluctuations that can occur with little to no manual labor based on the type of crop and external climatic situations.
4. Accuracy- Making decisions based on knowing exactly what the conditions within the greenhouse is reduces the number of assumptions that are made and gives farmers an opportunity to take fully informed decisions for the greenhouse.
5. Measuring run-off- Automating a greenhouse includes adding sensors that help in measuring and monitoring any run off from the greenhouse. This information is extremely helpful to ensure that the greenhouse is in accordance with the rules and regulations of the locality.
6. Reduces energy costs- Automating a greenhouse helps in reducing the overall production costs for the crop cycles. While the instillation of the automation procedures may be termed as a capital cost, its benefits can be observed in the long run as operating costs are drastically reduced.
7. Increase in yield and quality- Automating a greenhouse gives farmers the boost to search for better qualities of inputs which can be measured and compared with past performances. Learning from previous crop cycles will enable the farmers to get a better return on investment and increase the quality and quantity of produce.
8. Reduces uncertainty- Since the process of automation takes out all the guess work as compared to a manually operated greenhouse, the climate can be remotely monitored and altered without any problems or lengthy procedures. This reduces the unknow variables and can often provide and accurate yield quantity.

What can be automated in a greenhouse?
The level of automation in a greenhouse id often dependent on various factors such as the size of the greenhouse, structure of the greenhouse and average external affecting factors for the greenhouse. Various automations can be done in the following areas:
• Heating systems
• Cooling systems
• Ventilation systems
• Temperature monitoring
• Lighting systems
• Humidity control
• Carbon di oxide levels
• Irrigation systems
• Vents and roof systems

Complete control in a greenhouse helps in achieving the perfect conditions for plant growth that will help farmers reach their target quantities and quality. Farmers can rely on greenhouse automation equipment to reach the desired artificial micro environment. Its best to get in touch with a profession who can help in finding the right automation tools that will boost the greenhouse instead of being a liability and added expense to the farmers.

Most common greenhouse automation options:

1. Irrigation and fertilization systems- This refers to an automation in managing and monitoring the micro climate with regard to the fertilization process. This helps in irrigating large greenhouses and drastically reduces the risk of crop failure on large scale operations. It increases the efficiency in irrigation as water is evenly distributed at regular intervals of time. Indoor farming can be automated with drip irrigation systems that can be operated and controlled remotely and incorporate any natural changes in the environment.
   The set-up process for automated irrigation requires professional expertise and can be accurately installed by a team of experts to reduce operating costs and minimize water wastage.
2. Climate control systems- This refers to the automation in a greenhouse with respect to the temperature, lighting, carbon di oxide levels and humidity. All these factors together form the artificial micro climate for the plants to grown in. each plant requires a unique growing system and automating these factors can help in easily meeting the fluctuations that are linked with software’s to help provide the right training and updates in the automation process. Automating these factors will also help in creating a precise environment that can adapt to any changes with little to no manual labor. It helps in saving labor cost and groom the environment on a day-to-day basis. The remote access systems also come with sensors that provide an added layer of security to alert the farmers if the indoor climatic conditions do not match the pre set ones.

Regardless of the level of automation, greenhouses have already proved to be extremely profitable across the globe. Adding automation to the greenhouse cultivations boosts the profit margins and gives room for farmers to learn about the latest technology and innovations in their fields. The automation process adds value to a greenhouse and ensures that there is no wastage but maximum utilization of resources with the greenhouse.

What is green house farming?
Greenhouse farming refers to an agricultural practice where crops are grown in a sheltered structure that is covered by a transparent material like glass, plastic films etc. The main purpose of this is to provide the crops with a conducive external environment to grow in regardless of the climatic conditions prevailing naturally in that location.

Farming using greenhouses has various advantages and disadvantages that can be listed as:
Advantages:

1. Extension in growing season: when plants are grown in a greenhouse, they are no longer dependent on the external weather conditions. Any farmer can grow the desired plants and vegetables. The same temperature and humidity can be maintained in various ways within a greenhouse causing less stress on plants which ultimately leads to higher strength in them.
2. Larger variety: since the plants chosen for growth are not dependent on external environment factors anymore, crops can now be grown based on market demand and availability of crops even during off season times. Greenhouse also provides farmers with an opportunity to grow crops and flowers that could not survive in the natural conditions.
3. Reduce threats to crops: the most common problem in farming is pest attacks and insect invasions. This can be avoided as what goes into the greenhouse can be controlled and hence the risks of diseases are drastically reduced.
4. Fresh produce: since a green house facilitates year-round production of crops as they are not bound by the external climate conditions, fresh produce can be consumed throughout the year without the need for harsh cold storage and freezing of crops based on the season of production.
5. Others: higher profits, clean crops, soil free production, lesser labor, reduction in harvest time and cycles.

Disadvantages:

1. Lack of Pollination: since the entire environment of the greenhouse is externally controlled, naturally occurring processes like pollination are not facilitated. While pests can not enter the greenhouse, even pollinators will not be able to enter. This can lead to certain problems that have to be tackled artificially.
2. Operating expense: to ensure that the greenhouse is used to its maximum efficiency the greenhouse should be installed of good quality and maintained properly. Supplies used in the green house should be of good quality as well and must be maintained on a regular basis.
3. Initial investment cost: to install a green house the farmers must have some money to set up the frame and attain the covering materials. It can be considered expensive to build if the farmers do not have a steady instillation budget and is hence often considered as a luxury investment to farmers.
4. Expensive to heat or cool: automation in heating and cooling systems for extremely climates can be expensive and lead to higher bills. However, this cost can be negated by the pricing of the produce since the fruits and vegetables will be considered as either off season or exquisite.
5. Others: Need for alarms, extensive planning, income and competence to grow crops should be balance against the cost system.

What is a cold chambers?
A cold chamber refers to an enclosed structure that helps in the ripening process of plants and vegetables and increasing the shelf life of the fruits, flowers and other crops stored within the chamber. These chambers help in bulk handling perishables like fruits and vegetables in the line from production to marketing. It ensures that the produce stays fresh and consumable for longer periods by manipulating and controlling the temperature, humidity and lights inside a cold chamber system. It is however, important to ensure that the temperature is not extremely low or else the produce may go into a cold shock and end up being damaged.
A cold chambers was first created with bricks, sand and an enclosed roof made out of coconut leaves or grass. Sand was filled in between the brick walls and watered every day in the mornings as well as evenings. This is a zero-energy cold chamber that can be easily constructed for small farms and has proven to be as effective as an automated cold storage, that will cost much more to local farmers.

Advantages of cold chambers:
• Produce that is ripened in a cold chamber is much firmer as compared to produce that is ripened under external ambient conditions.
• The shelf life of the produce can also be increased drastically and the rotting process of the produce is decreased. Example: the shelf life of grapes can be increased to over 60 days if stored in a cold chamber as compared to just 8-12 days of shelf life if stored in ambient conditions.
• Reduces internal water loss and wilting of the produce
• Farmers can negotiate the right prices of the produce with middle men or even sell the produce directly as they will have enough time before the rotting starts and they do not have to come under the techniques of pressure sales and end up losing profits.
• Increase in preservation rates of vitamins of the produce and hence the quality of the produce can be maintained for longer periods of time.
• Zero energy cool chambers for small scale operations and other cool chambers that are built keeping in mind the cost and budget will actually consume very less energy but would prove to advantageous in the long run by solving the problem of reduced fresh fruits.
• Reduce the chance of attacks by micro-organisms or degradation caused by enzymes.
• A group of farmers can pool together and install a common cold chamber for all their individual produce and this can boost a positive co-operative operation and prove to be pocket friendly as well.

Features of a cold chamber:
• Temperature: The temperature inside a cold chamber can be automated and controlled based on the needs of the plants. It can vary even on a day-to-day basis and can reach as low as 4 degrees Celsius in certain high-power storages.
• Energy efficient: Cold chambers are extremely energy efficient if installed at the right size based on the quantity of produce. There are various models that can be adjusted to a certain degree to suit the needs of the farmers.

Pre cooling chamber:
Pre cooling chambers are designed in such a way that they help in removing excess heat from fruits and vegetables. Pre cooling chambers generally have evaporating units that suck cold air through perforations in boxes of the produce in order to attain the appropriate temperature within a few hours. Rapid cooling is achieved by maintaining the high levels of humidity within the chambers that promote a retention in the freshness of fruits and vegetables and also helps in avoiding fibre and weight loss in the same.

Pre cooling has various benefits like:

1. Lowering the workload and pressure on the actual cold chambers.
2. Preventing water loss, wilting, rotting and softening of the produce
3. Ensuring that the weight of the produce is maintained and there is no enzyme degradation.
4. Reducing and minimizing the respiratory activity of the produce post ripening.
5. Reducing the chances of cold shock for the produce when it is shifted to the cold chamber.
6. Preventing pest attacks and insect infestation.
7. Reducing microbial growth of fungus and bacteria hence helps in reducing the decay rates.

There are various factors that determine the right kind of cold storage and it is extremely important to understand the needs of the produce. It is best to gain professional help and decide upon the right variation of cold chambers that will not only be beneficial to the produce but also prove to be cost effective and pocket friendly.

There are various revolutionary changes in the Indian Agricultural system with a development in technology, markets and institutions that have an extremely important role to play. The green revolution brought about a massive change in the agricultural sector in the late sixties and early seventies which was a not-for-profit movement by the public sector. The mindset has recently been shifting to a for profit movement by the private sector that is not only boosting the income status of the farmers but also giving them an opportunity of development and advancement from traditional farming techniques.
The traditional farming techniques give them lesser yield which in turn leads to lower profit. If the farmers adopt the automation advancements, they have higher yield, higher profits which gives them a higher opportunity for development. The agricultural sector in India is extremely large contributing to about 15 percent of the total GDP and giving employment to more than half the Indian population. In this century, Indian overtook the United States to being the largest producer of milk in the world and is also amongst the largest producers of pulses, lentils, rice and wheat.
Credit for this growth can be given to automation developments such as irrigation systems, greenhouses and polyhouses. Greenhouses are considered to be the future of high-tech farming and have become extremely popular across the world. The Indian agricultural landscape has adopted the green housing mode of agriculture recently and has seen a lot of positive response through higher automation, lower labor force and higher yield.
Greenhouse farming refers to a process of growing crops in a greenhouse. A greenhouse is a closed structure that helps in creating an artificial micro environment that is conducive for the growth of that particular set of plants/ crops.
Automation in a greenhouse can be achieved by controlling the humidity, temperature, light and ventilation externally. This control allows the farmers to create and provide an environment that will boost the plant growth. A greenhouse that is installed based on the type of crops grown, size of requirement and other properly measured external factors can also help in preserving energy, reducing production costs and prove to be extremely pocket friendly to the farmers. They can also help farmers in exploring the growth of a wider range of plant and provide higher profits with the production of exotic fruits and vegetables like strawberries, blueberries etc. in India.
Apart from these benefits greenhouses prevent pest attacks and pathogen infestations giving farmers a certain level of surety with the production and output levels.
Keeping in mind all these advantages, the Indian greenhouse market has been growing at a phenomenal rate and has currently reached a market valuation of USD 190 Million and is estimated to grow even more. The increase in population and hence in food demand has on some level, forced the Indian farmers to search for better, sustainable and independent modes of farming and move away from the traditional modes. Greenhouse farming satisfies all the criterion for Indian farmers and is a rising entrepreneurial field with government backing.

What is a mist chamber?
A mist chamber refers to an enclosed structure system where relative humidity is maintained artificially with the help of mist instillations which spray water under pressure at a high level. The formation of fog induces acclimatation and rooting for the plants. Nursery plants that are propagated by cutting are grown in mist chambers. The high humidity levels ensure that the root initiation process is complete and the cooling effect within misting chambers ensures that the cutting is not dried out.
The use of mist chambers results in faster rooting for the cuttings and creates an optimum micro environment in which the root initiation is better. This helps in faster development of the plants and higher success rates with the cuttings. The mist chambers can be automated as the light, temperature and humidity levels can be externally and remotely controlled ensuring that the plants have a conducive environment for growth at all times.
Mist chambers are generally used for vegetative plants and seeds apart from research purposes. These chambers help in reducing the plant moisture loss and can also be extremely supportive in facilitating rooting of leafy cuttings. The size of the mist particles can vary between 50 to 100 micrometers.
Mist chambers can help in rooting of plants such as eucalyptus, bamboo and other medicinal plants and the hardening of tissue culture plants.

Advantages of mist chambers:
• Mist chambers facilitate a faster growth of cuttings and the rooting process
• They help in creating an optimum and appropriate micro environment for the root initiation and development process
• Ensures that the plants are not subject to a pest infestations, pathogens and insect attacks
• They have proven to have higher success rates in the propagation of hard wood cuttings
• Automation and external control of temperature and humidity ensure that the relative humidity can be maintained easily and remotely
• The mist chambers have a long life if installed and maintained properly and can be an extremely successful investment that gives returns quickly

Controls of a mist chamber:
A mist chamber has 5 main control mechanisms that operate together to maintain the relative humidity within the chamber:

1. Timer: there are two main types of timers that are installed in a mist chamber. The first timer is used in a mist unit that is turned on in the morning time and turned off in the evening. The second timer operates only during the day time and helps in the production of intermittent mist and intervals that are pre decided. The industry standard for this time is, one minute on and one minute and thirty seconds off.
2. Thermostat: A thermostat is used to control the temperature of the mist that is produced and released inside the mist chamber. It ensures that the temperature is maintained and does not become too cold or too hot for the plants to grow.
3. Photoelectric cell: This is based on the relation between the light intensity and transpiration rate within the mist chambers. Striking the right degree of balance between both these factors will ensure a conducive micro climate for the roots and cuttings.
4. Electronic leaf: an electronic leaf refers to a plastic with two terminals which is placed under the mist alongside the cuttings that in an alternate format promotes the drying and wetting of the terminal to break off the current which further controls the solenoid value of the mist chamber.
5. Screen balance: The screen balance refers to a screen made of stainless steel which is attached to a lever with the help of a mercury switch. The mercury switch is tripped in a situation where the mist on water weighs more and is controlled by the screen.

Components of a mist chamber:
A mist chamber consists of various parts as listed below that work together to provide the right micro climate for a conducive process of plant growth:

1. Structure: This refers to the external structure of the mist chamber that is generally a galvanized iron frame structure that is enclosed to incorporate the missing systems.
2. Plunge propagation bench: This refers to a bench that is generally made of metals like aluminum which provides a framework for the plant cuttings within the mist chamber
3. Professional thermostat: This refers to a rod thermostat that helps in gaining an accurate reading of the temperature within the mist chamber
4. Soil warming cable: This refers to a cable that is attached to the undersoil area and facilitates in warming the roots. This is connected with the thermostat and the temperature can be monitored and automated.
5. Misting systems: This refers to a system that helps in creating and maintaining a warm, damp and humid micro environment that prevents the cuttings from wilting or drying which in turn promotes quick growth of the roots.
6. Fogging system: This refers to a system of overhead fogging at the gutter height of the mist chamber to ensure the moisture levels within the chamber remain constant.
7. Solenoid valve: This refers to a valve that is opened and closed automatically that allows water to pass through as directed by the electronic leaf controller.
8. Other components: These are optional components in a mist system that can be installed based on the requirement of the owner. They include benching systems with fixed or movable tops, seeder machines, climate control sensors, horticulture lights and buffer rooms.

Hardening of plants in mist chambers:
After rooting in the mist chamber, it is important for the rooted cuttings to be hardened for better field existence. Misting should however not stop once the cuttings are rooted as this may lead to death of young plants due to dehydration and drying in accordance with scorching. The weaving off process should be continued and gradually reduced in which the misting system still operates but the number of sprays reduce.
Another method of ensuring the plants survive in a conducive micro environment is by moving them to a greenhouse or a fog chamber where the temperature is maintained at higher degrees and the relative humidity is lower. Whichever mode is chose, the hardening process should be done in a phased manner in order to ensure that the rooted cuttings are planted in permanent locations.
