All plant lovers and gardening enthusiasts wish for their plants to grow healthy and quickly. Here’s where a greenhouse often comes to mind. But the question is: Do greenhouses truly work? Would the plants grow faster in a greenhouse? By the end of this article, we will find out.
What is a Greenhouse?
A greenhouse, also known as a glasshouse; it’s a structure specially constructed to grow plants. Both its ceiling and walls are made out of a transparent material so that the sunlight can pass through.
This sunlight gets trapped inside the greenhouse, which increases the temperature and aids in faster plant growth. In addition to that, the temperature remains consistent within the greenhouse and promotes photosynthesis.
Greenhouses range in sizes. You can grow plants in a small-sized greenhouse or be constructed on a large scale. In fact, as large as a commercial building too. From flowering plants to fruit-bearing plants, a variety of plants can be grown inside a greenhouse.
Role of Greenhouse in Plant Growth:
Plants have to prepare their own food to survive and grow. They use carbon dioxide, water, and sunlight and prepare their food via a process known as photosynthesis. It’s no secret that a plant’s growth depends on photosynthesis. The extent/quality of photosynthesis depends on the concentration of sunlight, water and carbon dioxide that plants get.
A greenhouse proves to be a valuable resource for plant growth as it provides all these elements in an ideal and optimal concentration. It is a controlled environment where the sunlight is amplified. Water is provided externally, and the water molecules break down and become a source of carbon dioxide.
Moreover, since it is a protected environment, the risk of pest infestation or plants catching a disease is also reduced to almost zero when plants are planted inside a greenhouse.
You also have control over choosing the type of soil and adding fertilizers to the greenhouse as needed. In a nutshell, the caretakers have complete control over all the elements contributing to faster plant growth.
4 Things That Help Plants Grow Faster In A Greenhouse
A greenhouse does not provide all the nutrients that a plant needs to grow. It can deliver light and uniform temperature but providing the nutrients and water is the gardener’s responsibility.
1. Providing Light:
Since the greenhouse walls and roofs are transparent, the sunlight can easily come in. The construction material is usually plastic or glass, which allows light to enter and amplifies it so the plants can get maximum benefit. This is one of the most critical factors that help plants grow at a faster rate.
2. Absorption of Heat:
The plants directly absorb the light coming in through the walls and the greenhouse ceiling. This absorption converts the light into heat. During the absorption, the light’s wavelength is altered, and now it cannot leave the greenhouse. Since there is no way for the light to escape anywhere else, the heat absorption is maximized, and plants can benefit from the sunlight.
If you feel that the greenhouse isn’t heating much, there could be an opening or a leak somewhere. Make sure to check the corners and places where heat could be escaping through.
3. Raising the Temperature of the Greenhouse:
Now that the heat is trapped inside the structure, it is evident that it increases the greenhouse temperature. Once the temperature rises, the greenhouse’s closed environment ensures that it is retained and remains consistent. Therefore, plants are not exposed to temperature fluctuation whatsoever.
4. Promotion of Photosynthesis:
Heat and temperature are the two elements that help convert the nutrients, water and carbon dioxide into food for the plants. Now that these two elements are taken care of, the plants get to work, and photosynthesis leads to the promotion of photosynthesis and contributes to faster and healthier plant growth.
A greenhouse is a controlled and secure environment that facilitates plant growth. The transparent structure of the greenhouse allows it to capture light and convert it into heat. The plants then utilize this heat to aid photosynthesis and prepare their food.
No matter the weather conditions outside the structure, the temperature and heat are maintained inside the greenhouse. Plus, the risk of pest infestation and plants catching disease inside the greenhouse is also close to zero. Thus, it provides everything that a plant requires to facilitate growth.
When all the factors are provided in the right concentration, plants make full use of the opportunity and utilize photosynthesis to enhance the production of their food and, as a result, grow much faster.
