People are becoming more health-conscious; thus, the use of greenhouses is increasing day by day. Also, all the countries in the whole world use this unique method due to the increasingly warmer environment. A greenhouse is a human-made artificial atmosphere that is used to grow plants, flowers, fruits, and vegetables.
This transparent enclosure maintains the environment by using artificial heaters, lights, and humidifiers. As a result, we can have vegetables and fruits free from pests and bacteria at home. But, did you ever think why are greenhouses green? This useful article will discuss it in detail.
Why Are Greenhouses Green?
Actually, the greenhouse is referred to as a botanical garden. It is entirely made from transparent foil, glass, and polycarbonate. You can see the rion greenhouse as an example. It is filled with full green plants thus, it is visible fully green from the outside. So many people think that based on its look it’s called a greenhouse.
But, the greenhouse is not determined by its color. It is based on the glass structure and how the earth is affected by the greenhouse. The greenhouse allows sunlight to warm the inside air or plants by infiltrating the exterior. The process is just like the greenhouse effect. By absorbing the sunlight over the greenhouse, the soil or plants are transformed into heat energy. These are the main reasons why are greenhouses green.
How Does a Greenhouse Work?
A greenhouse helps to increase the growth of plants, fruits, vegetables, and flowers. It works by transforming light energy into heat energy. You should understand the process of how does a greenhouse work to get the most benefits.
Earth as Greenhouse
The greenhouse environment is the same as the earth’s environment. The increase in greenhouse gases like carbon-di-oxide, nitrogen-oxides, water-vapors, and methane results from the rising amount of heat. These gases stop sun rays from going back to space and gather them around the earth’s boundary. As a result, the ambiance of the earth becomes cozy and warmer. This is exactly the work process of the greenhouse.
A greenhouse is designed with transparent materials so that it can keep warm during and after sunlight. Actually, the warmth of a greenhouse is not determined by the sunlight. It is the materials that can help to make the atmosphere warm and causes plants to grow faster.
A greenhouse requires a warm atmosphere, but you have to make sure of the perfect temperature. Excessive temperature can cause harm to the plants. That’s why keeping the temperature under the control of the greenhouse includes a ventilation system. Some structures are designed with windows that help to let the excess heat out of the greenhouse. Also, it reduces the risk of attacking fungus in plants by providing proper ventilation.
Trap Heat and Light
To survive and grow well, plants generally need a warm temperature and light. A greenhouse can easily meet up those requirements for your plants. The transparent materials help make way for light to come inside and provide maximum sunlight access. After the light comes inside the greenhouse, the ground and plants absorb them, thus, convert into heat energy. The darker surface can absorb more energy than the lighter surface.
The heat energy gets trapped after converting the light energy into heat energy. They can’t escape from the greenhouse easily. That is why the inside air of a greenhouse gets warmer. Because of the airtight atmosphere, the warm air stays inside and helps to raise the inside temperature. The inside temperature of a greenhouse is much higher than the outside because of sufficient sunlight. So, on a hot summer day, it requires ventilation to keep the perfect temperature. With proper light and warm temperature, the greenhouse is considered the best place for occurring photosynthesis.
Working Process During Night-Time
As the greenhouse needs to be warm all the time, they store excess heat during the day. If your greenhouse contains high-density material, it can store more heat than the lower-intensity materials. Stone, water, and brick will take more time to heat up the building during the day.
But at night, it can release the stored heat slowly and raise the inside temperature. So, this process can keep the plants warm while the sun goes down. Some greenhouse owners keep a large fish tank inside it. So that the water can provide thermal mass to store the heat.
We can cultivate any type of vegetables, flowers, and fruits as per our requirement in a greenhouse. By using grow lights, plants can produce photosynthesis at night in the greenhouse, which outdoor plants can’t. The greenhouse controls the healthy growth of the plants because of its bacteria-free atmosphere. There is no fear about the season or weather when the plants are growing inside it.
A perfect location can decide how perfectly a greenhouse can work to produce healthy plants. Usually, south, east, or southeast-facing greenhouse can absorb the maximum amount of sunlight. You can place the greenhouse under the tree shades if the area is too hot in the summer. In the autumn season, trees will lose their leaves; thus, the greenhouse can get the proper sunlight.
In terms of insulation, location can influence the effectiveness of greenhouse. The freestanding greenhouse has lesser insulation and needs more external sources to heat the environment. You should place the greenhouse attached to a building. It will get proper insulation and heat from the shared wall.
A greenhouse has the perfect environment for protecting plants. Greenhouse maximizes the plant’s comfort and makes sure they grow healthy. The amount of light, temperature, and moisture makes the greenhouse perfect for cultivating plants.
This artificial source does not let you rely on nature for cultivating seasonal vegetables, fruits, and flowers. The best part is you can grow off-season plants with the help of a greenhouse.
