A greenhouse is essentially an enclosed structure that traps heat from sunlight or other sources of energy within its walls so that plants may grow more efficiently than if they were exposed to outdoor temperatures alone. Growing plants in greenhouses can help farmers produce healthier crops and better yields (due to protection from environmental stresses), while also reducing their environmental impact.
Greenhouses can create ideal conditions for the plants to thrive without having to rely on weather patterns or natural sunlight hours outside. This allows for more consistent conditions so plants have an easier time growing and developing their root systems before being transplanted outdoors. Additionally, they allow growers to start growing plants earlier than usual since they are not subject to the same seasonal constraints as outdoor plantings, and are protected from getting too cold in the winter or too hot in the summer; this means that harvest times can be extended by several weeks or even months. And greenhouses are helpful in controlling temperature fluctuations throughout the day, which helps ensure optimal growth rates regardless of what season it is outside.
Greenhouses help with pest control because enclosed spaces discourage pests from entering, while allowing beneficial insects like pollinators inside for better crop yields. Starting and growing crops in greenhouses allows increased protection from pests like insects or animals entering an open field setting outdoors. Greenhouse structures provide physical barriers against these intrusions while still providing necessary ventilation. Additionally, some types of plastic used on modern-day greenhouses even act as repellents against certain pest species, making them even more effective at keeping out unwanted guests.
Plants grown in a greenhouse are much more protected against disease outbreaks than those started outdoors, a problem which could potentially devastate entire crop cycles if left unchecked. And humidity levels within a greenhouse environment can be regulated more easily than those found outdoors; this creates an ideal atmosphere where disease-causing fungi cannot proliferate, due to lack of moisture on plant surfaces.
Since greenhouses are enclosed, protected spaces, the plants grown inside them don't need to be protected from pests and diseases by using dangerous chemicals. This results in safer, healthier food.
The concept of commercial farming in greenhouses has been gaining traction as a sustainable, environmentally friendly alternative to traditional growing methods. Growing plants in a greenhouse can help the environment in several ways:
