There are several types of growing greenhouses, and commercial greenhouses are among the most popular types used today.
These highly customized greenhouse structures feature a lot of configurations and alternatives that are designed to help you build an environment that fits your growing requirements perfectly.
Why do people prefer commercial greenhouses?
You can easily grow off season vegetables.
You can extend growing seasons to make up for demand, hence maximize yield.
Large scale efforts to grow plants are more sustainable and economically feasible for the medium to the experienced grower.
A variety of plants can be grown in different shelves and spaces of the greenhouse.
You can plan every inch of the structure for apt use by using separation walls, levels and hydroponics.
Costs of energy and maintenance can be mitigated with high yields.
The types of commercial greenhouses used for a business is usually aimed at supplying a wide range of fruits, vegetables and plants.
Greenhouse businesses usually include the production of greenery for use in the office or home, flowering plants for landscaping, or even vegetables.
Commercial greenhouses can be used to supplement all such needs and demands.
Factors that affect the building of commercial greenhouses
Setting up a commercial greenhouse has several advantages.
But before you jump into establishing one, you’ll have to think upon the following factors.
Commercial Greenhouse Considerations
You have to look objectively at your area. This includes space and climate. If you have not enough space, then that may be a limitation for setting up the greenhouse.
Weather controls and climatic conditions are also to be considered. If the weather condition is stormy, you may need components that are powerful enough to withstand such a climate. Gas and electric greenhouse heaters are used to maintain sufficient temperatures during winter season. Circulation fans and evaporator coolers are often required during the summer season.
Before choosing any greenhouse parts or supplies, the design of the structure ought to be complete.
Building commercial greenhouses takes time. On an average, its completion requires approximately 30 days, depending on the size of the structure. If you can’t dedicate your time, it is perfect to outsource your job.
You will need to find an efficient way for storing supplies of your commercial greenhouse. Using poorly cared equipment can have serious effects on vegetable and plant health.
Remember where your greenhouse structure will be located. Your greenhouse structure should meet area needs including, but not limited to, wind and snow load needs.
Knowing what type of vegetables and plants you want to grow and the budget you want to spend is also a crucial factor that can have an impact on setting up greenhouses.
Lastly, you will have to check with your regional development offices to know the land use rules and regulations of setting up a commercial structure.
What are commercial greenhouses made with?
The commercial or growing greenhouse is usually made from plastic or glass, covering plastic or glass walls with a roof.
The basic commercial growing greenhouse is made primarily of glass that is capable of allowing sufficient natural light and heat to enter through the ceiling or walls.
Greenhouse building materials used for the construction of the greenhouse can vary.
If building a structure from wood, cedar is a good choice due to its superb natural ability to resist insects.
Whether the greenhouse is made from metal, PVC or wood and topped with glass, plastic or fiberglass panels, you need to plan the structure in advance before buying the materials.
The requirement will hence vary.
If you are using a wooden frame, you will need wooden finish, nails or screws, hinges, a sealant and a way to connect the greenhouse covering.
Glass needs a special sealant and stronger frame to adhere to than wood.
Lots of greenhouse owners use glass metal supports that are melted into wood.
In such cases, the glass is set into the seal and supported with similar glues or silicone.
Metal frames need a completely different set of spare parts.
Lots of metal greenhouse structures come in packages or greenhouse kits, and can be anthologized with a screwdriver and a wrench.
They can also be designed from pipe materials very comfortably.
Interlocking pipes available in galvanized steel are also commonly used for building a greenhouse.
A metal frame is more durable than PVC or wood, but exceptional connections need to be put in place if the metal glass is used so that it does not contact the break and metal.
Kits for commercial greenhouses
Creating a commercial or growing greenhouse structure can be accomplished in many different methods.
Smaller businesses prefer to go with a greenhouse kit to manage the greenhouse construction.
The greenhouse kit includes framing, glass panels, and other accessories for creating a structure.
Greenhouse kits also provide cooling and heating components that help to provide humidity and temperature control.
A complete package greenhouse kit includes all of the required supplies for garden centers, commercial gardening businesses, market gardening operations, community gardens, plant nurseries and school greenhouses as well as universities and institutional gardening.
These kits often cover large spaces and are formed to building a wide range of plants.
They are often slightly expensive when compared to the cost of a normal backyard greenhouse and are available from a lot of manufacturers in several basic designs.
Types of greenhouse kits
In most cases, an arched kit design is used for constructing a garden greenhouse as it’s both easy to construct yet and economic.
But there are numerous complex and ornate commercial small greenhouse kits available as well to suit different needs.
A lot of commercial greenhouse kits are modular in structure to ensure an easy and quick construction process.
The modular designs greenhouse kits are very beneficial because they can be comfortably modified to create a smaller or larger greenhouse, depending on the requirements at any given time.
During hotter months, adequate ventilation is installed to allow for air and heat to escape.
A good ventilation greenhouse system is crucial to prevent overheating.
Some greenhouse growers prefer ventilating naturally by opening the doors and windows of their structures.
Constructed from either glass or plastic, solar greenhouses differ from standard greenhouse structures that absorb solar energy through their plants.
Solar greenhouses store solar energy when the sun is not shining.
This type of greenhouse is specifically used in the Northern Hemisphere where sunlight exposure may be limited, especially in the colder season.
As passive solar energy is the cheapest and easiest way to maintain consistent heat in a greenhouse structure, many growers are now turning to solar greenhouses.
Since passive solar energy heating depends on the sun, it is crucial to ensure the structure receives as much direct solar heating as possible.
The south side wall is typically covered in order to maximize solar energy retention.
Additionally, the north facing wall may be insulated to sustain heat from escaping.
Insulation could be placed over the greenhouse structure during nights and colder seasons to prevent further solar energy loss.
Brick, rocks or concrete on the dark ceramic flooring and northern exposure, will store solar energy for longer.
There are also certain plants and crops grown in water-filled containers that can boost the amount of the solar energy retained.
Solar greenhouses can be constructed as attached designs or freestanding models.
Attached designs are lean-to greenhouse structures are attached to the walls of a barn or house, thereby forming an extension of the property.
These greenhouse structures provide adequate room for kitchen herbs, transplants and other limited quantities of vegetables and plants.
Freestanding solar pit greenhouses are independent entities that have their own spaces large enough for the commercial propagation of vegetables, ornamental or herbs.
How does a solar greenhouse work?
Solar greenhouses, as their name suggests, utilize energy from the sun in order to meet their temperature needs.
The solar radiation from the sun passes through their surfaces to heat the ground.
The solar greenhouse design then traps this energy in order to maintain the higher temperature it needs.
The walls and ceiling of these useful structures also prevent the warmer air within from mixing with the cooler air.
A more technical way of saying this is that they prevent convection (heat transfer through moving gas or liquid) and conduction (transmission of heat from particle to particle within solids) from equalizing inner and outer temperatures.
Solar greenhouses will also serve to control internal temperature by controlling the transparency to the solar and terrestrial thermal radiation bands.
For a warmer temperature than the surrounding environment, more transparency is presented to the solar radiation band.
At the same time, more resistance to the thermal radiation band serves to trap the heat in the greenhouse.
A surface that is more reflective to solar energy while less restrictive to the thermal radiation band will, of course, have the opposite effect — a cooler environment than the sounding temperatures.
Generally, solar greenhouses are utilized for the purpose of creating a warmer environment.
For this, a material is chosen which absorbs some of the infrared radiation.
A portion of this radiation will be reflected back into the greenhouse.
Another effective aspect of solar greenhouses is the optimized usage of the soil base.
A portion of the available heat during the daytime will be absorbed by this mass.
At night, this soil becomes a source of radiant heat.
Sometimes, installing tubing for subterranean air circulation increases the effect of heat retention.
While a subterranean design can provide heating at night, it can also encourage cooling during the daytime through this same method of absorption.
Another method of encouraging this same effect of absorption is by utilizing storage materials with a high capacity for heat.
Bins of sand and rock or containers of water are such examples.
Solar greenhouses benefit greatly from the newest and latest plastic surfaces and glazing options.
With better material and design, a greenhouse owner is better able to control both the wavelengths of incoming solar radiation as well as those of outgoing thermal infrared radiation.
Greenhouse gardening for amateur or beginner-level gardeners
Greenhouse gardening is a satisfying and rewarding endeavor for amateur and professional gardeners alike.
Greenhouse maintenance also entails making sure your tools and supplies are working properly.
If you have a watering system installed, make sure it is running smoothly without any problems.
If you have a hose connected to your greenhouse, make sure it does not have any holes, cracks or blockages that are preventing it from giving your plants the adequate amount of water they need.
To check for problems like these, take off any attachments you might have on your hose and assess the water flow on its highest setting.
This will reveal any potential problem areas in the hose that you need to address.
If you discover holes or cracks in your hose, it’s time to replace it.
Remember to always include equipment checks in your greenhouse maintenance routine!
Prune and rotate your greenhouse plants
To keep the plants in your greenhouse healthy and strong, devote some time to pruning them and rearranging them when needed.
Trim off dead or dying leaves to make sure the nutrients from the soil are going to the living parts of your plants.
If you notice that there are certain parts of your plants that are getting more sun than others, don’t be afraid to rotate them.
Turning your plants will ensure that they receive an equal amount of light to grow evenly.
Make room for your plants to grow
Additionally, make sure there is enough space between your plants for them to grow.
If they’re close and crowded together, their growth can be hindered.
Use a ruler to make sure your spacing is consistent, or step back and view your pots to see if any are too close together.
Just like rotating your plants, making sure they have that extra room to grow will help ensure that all sides of your plants will be able to receive an equal amount of light.
Make greenhouse maintenance a part of your routine
Greenhouses require a lot of work to maintain, but it’s worth it for the thriving gardens they help create.
Make your greenhouse maintenance a part of your routine so that your plants receive the nurturing environment they deserve.
Greenhouse management as an occupation
Greenhouse management, as an occupation, incorporates aspects of many different disciplines.
Engineering, chemistry, biology and physics are all employed within the framework of a greenhouse.
Graceful integration of these varying aspects is the trademark of a well-trained greenhouse manager.
A greenhouse can be built around several basic designs.
Knowing what designs will enable the best use of space for growing is the key to effective greenhouse management.
The Quonset style, for instance, is a common design for a commercial greenhouse.
However, the arched style of this design means that there is limited growing space along the sides.
A gable style greenhouse, on the other hand, is built more like a house, with much taller walls supporting a pointed roof.
These are also much stronger designs and are, therefore, often made from glass.
Knowledge of biology and chemistry are essential parts of greenhouse management.
Because of the wide variety of plants contained within the average commercial greenhouse, a competent manager must be familiar with the biological and growth requirements for each species being sold.
Expertise is required for everything from the correct choice of growing medium to the appropriate fertilizer to lighting conditions and irrigation needs.
Proper nutrition is vital for growing healthy plants of any variety.
A greenhouse manager must be able to diagnose when there are chemical deficiencies or imbalances in plants.
These deficiencies can have detrimental effects on the plants and must be adequately addressed if the greenhouse is to be successful.
Irrigation is also an essential part of greenhouse management.
The irrigation system for a commercial greenhouse is the lifeblood of the operation.
Designing and maintaining these systems takes a great deal of knowledge and experience.
If done improperly, they can have adverse effects on the business.
Most greenhouses use watering systems that apply the water to the top of the grow medium.
But many also utilize hydroponic systems that have different maintenance requirements.
These systems can be further complicated by the variety of plants within the greenhouse, as different plants have different watering needs.
Effective greenhouse management must include knowledge of the chemistry of the water flowing through these irrigation systems.
Elements such as Magnesium, Calcium and Sodium must be monitored at all times to ensure proper plant growth.
The ability to properly balance these elements within the greenhouse water supply is often only gained through experience.
The ability to combine each of the above aspects, and use them in an effective manner, is the key to greenhouse management.
When you combine these pieces with the addition of personnel and supply management, the job of greenhouse management can seem like a daunting challenge.
However, as most people in these positions will attest, the rewards greatly outweigh the costs.

What are Greenhouse Made of?
A greenhouse is a building made of plastic, glass or wood specifically designed to create an ideal environment for plants to grow in them.
They work by trapping solar energy within their walls and transferring them onto the plants.
Solar greenhouses, commonly used in the Northern Hemisphere, are more effective in using the existing solar radiation to increase temperatures within the greenhouse.
They use different techniques to transfer heat into the soil, trap sunlight even when adequate amounts are not found in the atmosphere and retain heat by using several items like sand bags, rocks and bricks.
