Chapter 1 what is Greenhouse and how it works?

Light energy is converted into heat energy in a greenhouse. Sunlight rays penetrate the greenhouse and are consumed by plants and materials, converting them to gas. The heat energy is released by the items in the greenhouse, but it is trapped by the glass in the limited room of the greenhouse (or plastic sheeting).

In a Greenhouse, What Happens?

The most straightforward explanation for how a greenhouse operates is that it converts light energy into heat energy. Via the clear sheeting or sheets, the sun's rays beam into the greenhouse. The sun's light is absorbed by the greenhouse's objects, including the plants, and converted to heat.

The above video from Science with Bobert explains how a greenhouse operates and how various colored objects respond to sunlight. Yellow-colored objects capture light and warm up, while dark-colored objects emit light and cool off.

Why doesn't the heat just quit the greenhouse if it was too easy to get in? There are two explanations for this.

First, structures that have absorbed light emit heat steadily at first. Plants and things like a dark-colored table orbits of black-painted cement don't take long to warm up. They do, though, take a long time to cool off.

The artifacts emit their thermal energy back into the air as they cool off. Warmer air is cooler and climbs to the greenhouse's roof. Cooler air flows down to the ground and objects, absorbing the energy that is being emitted.

Once the heated air reaches the roof of the greenhouse, there is nowhere for it to go. While light and heat will easily pass through glass or plastic sheeting, heat does not. While glass and plastic are not the best insulators, they do help to keep the greenhouse warm.

THE EFFECT OF THE GREENHOUSE

The Earth is, in many respects, its own greenhouse. A dense layer of atmosphere surrounds it, preventing warm air from escaping into space. In this scenario, the atmosphere acts in the same way as glass or plastic in a greenhouse does.

Heat and light are trapped in greenhouses.

To live and expand, plants need light, warm temperatures, air, water, and nutrients. Each of these necessities has different specifications for different plants. A greenhouse meets the first two conditions for your plants, but the last three are up to you.

Step 1: Let the Light In

Greenhouses must provide a way for light to enter in order to provide illumination. This is why greenhouses are mostly constructed with transparent materials such as glass or clear plastic. This allows the plants inside to get as much sunshine as possible.

Step 2: The Heat Has Been Absorbed

As light enters the greenhouse through the glass windows, it is absorbed by the plants, the earth, and everything else in the greenhouse, turning it to infrared energy (also known as heat). The more energy a surface can consume and convert to heat, the darker it is. This is why, in the summer, black pavement gets extremely hot. It is consuming a significant amount of heat.

Step 3: Heat Is Captured

As light energy is transformed to infrared energy (heat), it takes on a different form than light energy, which is known as wavelength by scientists. The difference in wavelength prevents heat from quickly escaping through the greenhouse's glass windows. So, though getting in was easy, getting out is more difficult.

Warming the Greenhouse (Step 4)

The trapping heat warms the air inside the greenhouse, and since greenhouses are comparatively airtight, the hot air remains inside, increasing the temperature of the whole structure. This is the same phenomenon you've probably seen when climbing into a car after it's been parked in a sunny spot for a few hours. It's warm and inviting.

Step 5: Maintaining the Body's Temperature

With enough sunshine, the temperature inside a greenhouse can easily exceed the temperature outside; in reality, on a hot sunny day, you will need to ventilate the greenhouse all day to prevent the plants from actually burning. Due to the lack of sunshine on overcast days, the greenhouse will heat up more slowly, if at all. As a result, greenhouses are more effective in places with a lot of sunlight.

Promoting Photosynthesis is the sixth step.

All of this light and warmth provide plants with all of the light and warmth they need to thrive. This is due to the fact that they have ideal photosynthesis conditions. Photosynthesis is the process of a plant mixing carbon dioxide from the air with energy from the sun to produce basic sugars, which it then uses as fuel. A plant, like a cheeseburger, uses the sun to grow large and solid. Plants need about six hours of sunshine a day on average, but this varies based on the type of plant; positioning your greenhouse so it will receive full sun all day will guarantee that the plants within receive enough energy.

When the Sun Isn't Shining

The majority of a greenhouse's exterior is made of plastic or glass, which is perfect for letting in as much light as possible but is a weak insulator (it doesn't retain heat well). This ensures that the thermal energy passes into it on its way to the outside world. This doesn't matter as long as the sun is shining because light energy gets in faster than heat can escape. However, all of the thermal energy will soon dissipate at night, leaving the plants vulnerable to lower nighttime temperatures. You must either store excess heat during the day or use an artificial heat supply at night to cover your tender plants.

Storing Heat throughout the Day

Different materials require different amounts of energy to heat up (compared to dirt or gravel, bricks take longer to get warm), a property known as thermal mass. The higher a material's density is, the more energy it takes to increase the temperature of that material. So, high density materials can hold a lot of heat. Examples of high-density materials include:\s• Stone

• Brick \s• Water \sFlooring Matters

Adding a brick floor to the greenhouse ensures that during the day it would take longer for the building to heat up, but during the night, all the excess heat energy will slowly be liberated into the air inside the greenhouse. This will maintein your plants warm and toasty long after the sun goes down.

Dual Use Features

Some enterprising greenhouse owners multi-task by maintaining huge fish tanks within their greenhouses. The water in the tank provides plenty of thermal mass to store heat, the fish grow faster and are more efficient thanks to the extra warmth, and the waste retrieved while an excellent fertilizer for the greenhouse plants can be made cleaning out the fish tank.

Adding Artificial Heat

If you plan to add more thermal mass to the greenhouse, that isn't an option, you can always resort to bringing in an artificial heat source such as a space heater. Ideally, you'd like a heat source that you can attach to a thermostat so that it automatically holds the temperature inside within the desired range. Greenhouse supply stores sell many varieties of artificial heaters built especially for use in greenhouses.

Meeting the Plants' Needs

Although greenhouses are highly efficient at their two strong points - providing light and heat - your plants will still need your support to meet their other needs. In reality, the high levels of light and heat also cause plants to use up nutrients and carbon dioxide at an accelerated pace, meaning you have
