Definition - What does Prefabricated Greenhouse mean?
A prefabricated greenhouse is a kit that a person can buy that contains all of the necessary components of a greenhouse. The contents of the kit includes a prefabricated unit with cladding, a frame, and ventilation ports. Prefabricated greenhouses are great for beginners, as they are convenient and even portable in some cases. They are considered an 'out of the box' solution to owning a greenhouse.
Prefabricated greenhouses usually include wood, plastic, or metal varieties, and are available at garden centers and big box retailers during the gardening season. Increasingly, more consumers are also ordering prefabricated greenhouse kits from online retailers.
A prefabricated greenhouse is a building-like structure that is often just a small unit with zippers, tent poles, transparent plastic sheeting, and shelves only meant to house plants. Prefabricated greenhouses might also resemble small sheds.
MaximumYield explains Prefabricated Greenhouse
Like regular greenhouses that are 'built from scratch' prefabricated greenhouses feature walls and the roofs that are made up of transparent materials to let in sunlight and create a desired atmosphere inside, protecting the plants from outside weather.
There are many different types of greenhouses growers can choose from. Prefabricated greenhouses, likewise, come with many options such as screening installations, and options for heating, cooling, and lighting.
There are many advantages in using a greenhouses including light and heat for crops. For example, techniques are adopted for optimal comfort ratio of the micro-climates such as air temperature, relative humidity, and vapor pressure deficit for maximum and optimal crop yield. Light and heat are essential when it comes to plants’ survival and growth and different plants have different necessities. Greenhouses are typically made up of translucent materials, either glass or clear plastic. This allows sunlight to enter the greenhouse for plants to use for the process of photosynthesis.
There are also greenhouses that trap warmth from the sunlight inside for better crop yield. Basically, when the light hits a solid surface, the solid surface tends to absorb some of the light energy and turn it into infrared energy or heat. The darker the surface is, the more energy can be absorbed and turned into heat avoiding radiant heat loss and prefabricated greenhouses work well with this.
This infrared energy has a different wavelength than light energy and so while it can pass into the greenhouse, it takes a longer time to escape from the greenhouse. Thus, the heat that is trapped inside the greenhouse warms the air and since the greenhouse is air-tight, the warmer air stays inside, resulting in an increase of the building’s temperature. However, on hot sunny days, the greenhouse should be ventilated all day to keep the plants from cooking inside. Alternatively, on cloudy days with no sunshine, greenhouses tend to heat up more slowly.
