Gardening enthusiasts in the more interesting temperate climates and any place where there are four seasons are faced with great benefits as well as challenges. Because of the four seasons, gardeners are blessed with huge plant varieties conducive for planting on one or two of the seasons. In the period of a year, they are given an opportunity to plant varieties that must grow in cooler climates, and take advantage of the sunny summer to plant those that would require more exposure to the sun. However, the seasonality of plant varieties may pose challenges to those who would rather grow plants continuously, regardless of season. This is especially true for flower and fruit varieties that require continuous sunlight for an entire year, for example, or fruit and vegetable perennials that do not bear fruit and instead shrivel up in the winter.

The response to these challenges is the creation of greenhouses or greenhouse facilities. A greenhouse is a structure made of glass or plastic that stores up the sun's rays in order to simulate the temperatures in the spring all year long inside. By storing up heat inside a greenhouse, it allows individuals to grow plants continuously even while winter rages hard outside it. Greenhouses also go by the name glasshouses or hothouses. The glass or plastic used in the construction of greenhouses are specially designed to have transmission qualities that will allow for the sun's ultraviolet rays to be stored inside the greenhouse facility, providing a warm atmosphere inside, and in effect, warming the plants and the soil. A greenhouse leaves little or no openings through which the air heated by the stored sunlight can escape; leaving a small window or hatch open in a greenhouse will lead to a drastic drop in temperatures.

The general idea of a greenhouse is to protect temperature and climate sensitive plants from extreme shifts in temperature?either too hot or too cold. Maintaining a greenhouse has its own share of toil. Unlike the normal outdoor environment, which may be left to its own devices to some extent as nature creates some degree of balance, a greenhouse must be placed under strict regulation. Inside the greenhouse is a controlled environment that must simulate the outdoors without overdoing it. For a start, it must regulate heat and humidity inside the facility. Other factors to be considered are irrigation of the plants (and sufficiency of the water available to them), light exposure, and the presence of pests and diseases must be put into great consideration. Moreover, due to the fact that the spring outdoors is sealed into a single facility, natural activities like pollination must be simulated by the introduction of species that will help make this possible. Bumblebees are the most popular option for pollinators in greenhouses.

It is recommended that greenhouses be built in the southeast portion of the property. It is in this way that the minimal sunlight available during the winter will be maximized by the greenhouse. Moreover, the house can serve to protect the greenhouse from strong winter blizzards coming in from the north.

Greenhouses may be built attached to a house, or as stand-alone structures. The latter option provides more growing room for the greenhouse facility. While it may seem that there is too much to do in order to simply start a greenhouse, gardening enthusiasts will be more than willing to vouch for greenhouses, especially if gardening is a hobby. Gardening affords even the busiest of folks to tend to their plants when they are available. With a greenhouse, the constraints of day and night, and even the seasons, are put in the backseat. Greenhouses provide the option of tending to gardens even at night because lighting and heat is consistently present inside the structure.

Moreover, it gives gardeners the ability to plant exotic flowers and fruits that are usually grown in warmer tropical areas as they are able to control light exposure and heat inside the greenhouse. Greenhouses may even provide profit-making possibilities for gardeners. With potted plants for indoor growing and flowers growing in demand, greenhouse owners are given opportunities to sell what they grow inside their greenhouses to buffer whatever maintenance costs they incur along the way. In the higher-latitude territories, greenhouses carry the important task of growing fresh produce in areas where the climates are harsh and cruel on plants. This is one of the biggest reasons for huge greenhouse facilities that house vegetables and fruits more than flowers and exotic foliage. At the end of the day, greenhouses allow for the creation of a miniaturized and highly controlled natural environment to suit gardening needs. Its growing potential to provide for fresh produce in territories even with the instability of global climate proves to be a benefit that may be explored in the future.
