Greenhouses – An Important Learning Experience
Greenhouses are buildings that hold plants that are used for their foliage and flowers during droughts or warm weather conditions. They have been in use since the 16th century. Today, a greenhouse (or simply a greenhouse) is any building where plants including vegetables and flowers are grown. Usually it has a translucent or glass-enclosed glass roof.
Greenhouses in Mexico are famous for growing plants all through the year because of its tropical climate. A good thing about having a greenhouse in your backyard is you can use it year-round. In the United States, a greenhouse might be more beneficial during the winter months because temperature requirements of different plants can be varied depending on their growing seasons. Greenhouses provide an environment that is ideal for starting seedlings, for propagating cuttings, for training seedlings, and for monitoring plant growth. A green house is also an excellent location to raise small animals like goats and chickens as they can be cared for in a confined space without predators around.
A greenhouse keeps plants safe from extreme temperatures by providing a shield against solar radiation. During summer it provides shading to prevent direct heat from getting to the roots of plants while at the same time preventing direct cold from getting into the ground of plants and seeds. Greenhouses are good for seedlings to be planted in during droughts by providing protection against temperature extremes. This also prevents the damage caused by insects during droughts. During cold droughts, heat can reach the roots of plants before they are able to absorb this heat. This will kill the plant and is one of the reasons why seeds are not properly germinated in cold climates.
If you are looking for a nice spot for a greenhouse there are many different types available. There are portable types that you can move wherever you want such as freestanding greenhouses that have wheels and are lightweight. Larger models that are freestanding can be placed on a patio or deck. These are great if you like to sit out in the sun for long periods of time as the larger models tend to get a lot of sunlight throughout the day. There are also table-top models that can be placed indoors and will provide adequate sunlight during the day for growing plants. However if you do not have any of these options then your best choice would be a freestanding model that is stationary outdoors.
The primary purpose of a greenhouse is to provide shelter for your plants from the harsh elements of both nature and man. Most greenhouse manufactures have created models that are built with durable materials that will withstand high winds, heavy rain, ice and snow. Greenhouses should always be kept at a consistent temperature for optimum growth of plants. While many greenhouse manufacturers do recommend varying temperatures between seventy and eighty-five degrees, it is important to follow guidelines such as those found on the National Hydroponics Association website which states that “temperatures between seventy and eighty-five degrees are ideal for most tropical plant life”. Greenhouses should also be made of durable materials and come with a security lock. Even though it may be tempting to buy a cheap greenhouse that you just throw away after using it, this just adds to your stress level and causes unnecessary stress on your plants.
One final consideration for purchasing a greenhouse is the consideration of heating. Most greenhouses will come with at least one standard heater and usually multiple lamps for use during daylight hours and when temperatures are cooler. This is usually referred to as “casing heat” because the lights that provide the warmth are enclosed in a case that fits around the perimeter of the unit. Greenhouse heating is extremely important and it should be carefully considered. You will need to consider the amount of light your plants will need and where in your garden the heating source will be located. The greenhouse itself will determine the best heating solution for it but you will also need to factor in the cost of electrical and gas lines, the availability of fuel for the greenhouse and any other environmental considerations.
