What do greenhouses, glasshouses, and hothouses have in common? They all refer to a facility that controls the environment where specific crops are to be planted and harvested. In countries where harsh weather and climate conditions are manifest, greenhouses have revolutionized the green industry. By use of such a facility, one is able to control certain factors such as heat, temperature, and the like; creating or extending a growing season.

The Benefits of Greenhouses

A greenhouse traps heat and saves it for future use. Being able to grow one kind of plant, say out of season flowering shrubs, regardless of the external weather conditions is the main benefit of having a greenhouse. This in turn leads to the practical benefit of making certain crops, fruits, and flowers available all year round regardless of the season and weather.

A greenhouse gives you more control over the conditions that affect your plants’ growth. It gives you the ability to predict with a certain degree of accuracy how much crop you will harvest, unless of course something goes wrong in any of the various aspects and processes involved in its operations.

Because of these benefits, an enterprising individual can actually supply out of season flowers and crops and thus gain more profits because of it. The predictable plant production of greenhouse also gives a businessman a better handle on his business economics.

Construction of the Greenhouse

The materials commonly used for greenhouses include plastic and glass. These are specially modified materials that allow heat storage. Heat can then be allocated for future use so that the greenhouse can be maintained at a specific temperature all-year-round. Moreover, these structures have little or no openings because the warm air might escape and a drop in the temperature may lead to unfavorable results.

Greenhouse Limitations

Greenhouses need to comply with certain engineering specifications; this requires special design/build skills and specialized materials. Moreover, greenhouses need a lot of maintenance. Unlike normal gardening, greenhouse conditions must be strictly controlled and monitored. There are various systems for heating, cooling, circulation irrigation, and pest control. There may be specialized equipment for seeding, transplanting and potting. A greenhouses production numbers depend largely on how well the owner or the greenhouse operator has been able to maintain it at its optimal working condition.

Greenhouse for Hobbyists

Despite the costs and efforts needed to maintain a greenhouse, there are still a number of gardening aficionados who choose to maintain such facilities. While most people put up greenhouses for business purposes, there are hobbyists who maintain greenhouses for the pleasure of starting their own plants from seeds and cuttings, or to grow loved plants that would not survive the local climate outdoors. Greenhouses also make it possible for these gardening hobbyists to attend to their plants anytime they wish to do so.

Choosing specific greenhouse lighting can be somewhat tricky. Here are five important factors to consider when making your selections.

1. Type of greenhouse — Before buying greenhouse lighting, you must understand the kind of greenhouse that you have. Is it a commercial greenhouse or a personal one? Knowing what type of greenhouse that you have will determine what kind of lighting to choose. For instance, if you have a commercial greenhouse, it is best that you buy lighting that is created to endure humid, adverse conditions that are commonly found in commercial conservatories. Research your options before making any purchase.

2. Length of use — The duration of light use in greenhouses based on a “photoperiod”– the period in which the light will be used may vary. For example, you may use lighting for a “12-hour photoperiod.” This means that within 24 hours cycle, lighting will be used for 12 hours and 12 hours with no light at all. It is important to buy a light that meets your specific usage needs. Find out what your needs are before making your selections.

3. Purpose — Buy a light that will focus on your desired results. For instance, if you want to motivate the growth of your orchids, it is best to buy a light that will put more weight on the “spectrum colors” like the red, blue and the “far-red wavelengths.” The colors of the light have notable effects on the plant growth. Not all light will produce the desired results. Talk to experts before purchasing.

4. Electrical efficiency — Opt for lighting products that provide optimum effect without having to compromise the amount of energy that they consume. It’s better to buy lights that are efficient and can still conserve as little energy as possible. Ensure that the lighting you buy meets your electrical efficiency requirements.

5. Heat — Remember that lighting should only be used where it is needed. A light that emits more heat as it releases light can be very harmful. Too much heat on a plant will trigger its death. For example, it’s not a good idea to buy an incandescent bulb because it gives out too much heat. Make sure you understand how much heat each lighting option produces before purchasing.
