Once you make up your mind to build a greenhouse the next major decision is what type of greenhouse you should select. This will be an easy decision if you are aware of what plans you want to grow and a rough quantity. However if you  provide answers to below questions it'll be an easy decision.

For what purpose the greenhouse is used? For growing , for Luxury living or anything else?
What size do I need?

  • *Will it be a major appeal in my garden or I just need to get the work done?
  • *Is it exposed to strong wind or other noticeable weather conditions
  • *Any kids, pets or wild animals will be in the area where the greenhouse id going to be.

Features , cost and space will help you decide on the best type of greenhouse you need to build for your purpose. As an example if you live in a  very windy area it's better paying up a little extra to build a much more strong  hard and well-built greenhouse. However if warmth is the main feature you should focus on a greenhouse with temperature control. Greenhouses differ based on the structural design as well.

There are commonly three types of greenhouses based on the structure:

  • * Detached
  • * Ridge and furrow or gutter connected.
  • * Lean-to

Detached Greenhouse

A Detached Greenhouses

Same as the name detached greenhouses are a self-governing and stand alone individual arrangement. They can still be connected to a work area or to another greenhouse connecting pathway. However the growing area is restricted to the areas just around the side walls and it will weaken the productivity and efficiency.

Ridge/Furrow Greenhouse

A Ridge/Furrow Greenhouse
These are the greenhouse types that are attached at the lower ends of the roof by a gutter. These ridge and furrow greenhouses are mostly built with gabled or curved archways. Gabled greenhouses are generally suitable for heavy coverings  such as  glass, fiberglass and curved arch greenhouses are mostly enclosed with lighter material  such as polyethylene.

Lean-To Greenhouse

A Large Lean-To Greenhouse
This is a very rarely used greenhouse for commercial purposes due to the size restrictions, however this is mostly popular for personal use.

There are three types of greenhouses based on the temperature control feature:

  • Cool greenhouse
  • Warm greenhouse
  • Hot greenhouse

Cool Greenhouse

A Inside View of  Cool Greenhouse
Even though it's called a cool greenhouse this is a frost free greenhouse.  There is a pleasant spring type temperature series from forty to forty five degrees Fahrenheit . This is however perfect for growing little plantlets or any plants that do not need any warm temperatures to stay alive. This is ideal if you are planning to start growing during hot summer months and use of additional heat or lights isn't necessary for a cool greenhouse.

Warm Greenhouse
Inside a warm greenhouse the temperature is maintained at about fifty five degrees Fahrenheit. This will be an ideal temperature for a wide variety of plants can be grown, and gives the feeling of an outdoor garden. These types require additional warmth and light throughout the cold winter months.

Hot Greenhouse

A Hot/Heat Greenhouse
Inside warmth for a hot greenhouse is kept at a minimum of sixty five degrees Fahrenheit. You are able to increase the temperature of this, however as this is mainly targeted to grow tropical and exotic plants and if you live in a very cold and snowy state, you will need to set up additional heating and lighting gear to implement the tropical weather requirements inside the greenhouse.

Greenhouses can be also classified according to the types of materials material they are made of. As an example glass, fiberglass, or plastic each will have it's own set of  type has advantages and disadvantages.

Glass Greenhouse

A Glass Greenhouse
This is the most traditional type of greenhouse covering material used. This mainly comes with Aluminum structures to ensure that you get a weather tight greenhouse structure. These Glass covering greenhouses comes in different sizes and shapes to meet the requirements such as budget and space availability. However the main disadvantage of a Glass Greenhouse is it's easily breakable and due to that there will be a high maintenance cost. visit here for more details.

Fiberglass Greenhouse

A Fiber Galss Greenhouse
Fiberglass is modern and used in many industries for various uses now a days in the industry. These greenhouses are Not heavy as the glass greenhouses, they are strong not easily breakable and even hail proof. However as a disadvantage low quality fiberglass will discolour when it's exposed to sun and rain for some time hence if you are using a good fiber glass it'll be expensive same as the glass greenhouse.

Plastic , PVC , Polyethylene Greenhouses

A Polyethylene Greenhouse
These are lightweight and cheap and transparentness is readily available as well. When properly installed, these can last for about a period of  five to six years. These normally works well during Autumn and Winter but when it is the hot summer period the polyethylene/plastic will easily be damaged. However this is widely used for personal use than for commercial use. Visit here for more details.

A Quick Glance Into A Greenhouse

What is a greenhouse?

Yes the first question is what is a Greenhouse? It is a building formation where plants such as fruits, vegetables, flowers are grown in right warmth. It magnetize warmth from the sun and inside a greenhouse sun’s electromagnetic radiation warms the plants, soil, and other components within the greenhouse to provide a pleasant environment for growing. Not only for growing outdoor  warm swimming pools too can be built within a greenhouse to be used during cold winter days.

How the greenhouse ideas first popped?

The very first greenhouse idea goes back to the days of the Romans. They were the very first set of people who created formations to protect their plants. They used heated pits and used rock slabs to form the prehistoric greenhouses they used.

In the 17th and 18th centuries the word “glasshouse” which is the correct name of this formation, was adopted.

At that time, they made a mistake by believing that heat was more important to the plans than light. Due to this many structures were built to exclude the entry of light, but by the time the glass tax of 1845 was eliminated, the designs of these early stage greenhouses started to change rapidly.

Greenhouse builders realized that a curved roof as a replacement for of a flat one permitted high absorption of the sun’s rays and by using iron as a substitute to  wood, the greenhouse could be structurally stable and made capable of gripping more light.

It has been more than forty years now since the major upgrading in materials and design have been incorporated into the greenhouses, and small scale greenhouses are now very much a attribute of any home garden.


Mechanism behind the greenhouse capturing heat?

A very special kind of glass is used in greenhouses which acts as a intermediary which selectively send out spectral frequencies.

Simply the spectral frequency can be described in terms of the principle any object in the world releases, radiates or broadcast light and the circulation of this light along an electromagnetic spectrum is determined by composition of the entity. For that reason, the special glass of a greenhouse grab energy inside the greenhouse and that supply the needed heat for the plants and the soil inside the greenhouse. This mechanism warms the air close to the ground and prevents it from rising and exiting the boundaries of the greenhouse structure. As an example, if you open a small window / vent near the top or roof of a greenhouse, the temperature drops considerably.

This happens  due to the auto vent automatic cooling system which is used by greenhouses that maintains a variety of temperatures inside it. This is how greenhouses trap the electromagnetic radiation and avoid convection.


The advantages of greenhouses :

There are many advantages of having green houses. The main advantage is the capability to expand the growing season even when the weather is getting colder. Early stage fruits, vegetables can be planted indoors and then transfer them when they have grown-up. A several additional weeks will be gained by these greenhouse owners for the growing and sowing period particularly if there is a heating system installed in the greenhouse.

Addition to expanding the growing season to the cold season and being able to control temperature, light and moisture in a greenhouse, the farmer or gardener can sharpen their skills by getting familiar with as many diversity of plants as he can in the greenhouse. Visualize being able to grow juicy tomatoes , chilies or creating new plant kinds by this simple act of breeding.

Even if you have a limited outdoor space your garden or that is completely paved or concreted as in many apartments you can still make use of limited space by using small sized greenhouses. These are what people call “free standing” greenhouses which just takes a few square feet of space to build up and these can be even installed on small balconies or roof tops.

Greenhouses will also provide protection from the harmful elements to the plans and even from birds and animals. It also provides easy access to the elderly and disabled, given the fact that greenhouses are less physically challenging than a wide open field.

In addition to all these uses within a green house a warm summer environment can be created throughout the year for luxury lifestyles.

The Greenhouse Structure

0 comments
The greenhouse structure represents both the barrier to direct contact with the external environment and the containment of the internal environment to be controlled. By design, the covering material allows for maximum light penetration for growing crops. A number of commercial greenhouse manufacturers and greenhouse designs are suitable for greenhouse vegetable crop production. The standard greenhouse design used for vegetable production, is a gutter connect greenhouse.

Rough gutter conned, double poly, vegetable production greenhouse

By design, a gutter connect greenhouse allows for relatively easy expansion of the greenhouse when additions are planned. Gutter connect greenhouses are composed of a number of "bays" or compartments running side by side along the length of the greenhouse.

Typically, these compartments are approximately 120 feet long by 21 to 25 feet wide. The production area is completely open between the bays inside the greenhouse. The roof of the entire structure consists of a number of arches, with each arch covering one bay, and the arches are connected at the gutters where one bay meets the next. The design of a gutter connect greenhouse allows for a single bay greenhouse of 2,500 feet to easily expand by the addition of more bays to cover an area of 1 hectare (2.5 acres) or more.

With a gutter connect greenhouse, the lowest parts of the roof are the gutters, the points where the adjacent arches begin and end. The trend for gutter heights in modern greenhouses is to increase, with greenhouses getting taller.

The reasons for this change are two-fold: firstly, newer vegetable crops like peppers require a higher growing environment. Peppers will often reach 3.5 meters  in height during the course of the production cycle, so taller greenhouses allow for more options in crop handling and training.

Secondly, taller greenhouses allow for a larger air mass to be contained within the structure. The advantage is that a larger air mass is easier to control, with respect to maintaining an optimum environment, than a smaller air mass. Once a grower has established an environment in the larger air mass, it is easier to maintain the environment.

Typical gutter heights for modern greenhouse structures are 13 to 14 feet and are quite suitable for greenhouse pepper production. The trend for future gutter height is to increase further, with new construction designs moving to 16 to 18 feet.

There arc a number of options for greenhouse covering materials: glass panels, polycarbonate panels and polyethylene skins. Each of the coverings has advantages and disadvantages, the main determining factors usually being the trade-off between cost and length of service. Glass is more expensive, but will generally have a longer service life than either polycarbonate or polyethylene.

The United States vegetable production greenhouses are constructed with double polyethylene sheets. Two layers of polyethylene are used, with pressurized air filling the space between the two layers to provide rigidity to the covering. The life expectancy of a polyethylene greenhouse covering is about four years.

Energy conservation is also an important factor. The covering must allow light into the greenhouse and yet reduce the heat loss from the greenhouse to the environment during the winter.
New coverings are being developed that selectively exclude certain wavelengths of light and, as a result, can help in reducing insect and disease problems.
