Plastgróðurhús

Plastgróðurhús is an Icelandic term referring to a greenhouse constructed with plastic sheeting as its primary covering material. These structures are commonly used for horticultural purposes, allowing for the cultivation of plants in controlled environments that are protected from harsh weather conditions. The plastic covering, typically made from polyethylene or PVC, offers several advantages including affordability, flexibility, and ease of installation.

The primary function of a plastgróðurhús is to trap solar radiation, creating a warmer microclimate inside than the ambient outdoor temperature. This increased temperature, along with protection from wind, heavy rain, and frost, extends the growing season and enables the cultivation of a wider variety of crops, including those that might not thrive in the local climate. Ventilation is crucial in plastgróðurhús to regulate temperature and humidity, prevent disease, and ensure adequate air exchange. This is often achieved through manually operated or automated vents.

Plastgróðurhús can range in size from small, backyard hobbyist structures to large commercial operations. Their simple design and relatively low cost make them an accessible option for many gardeners and farmers. The lifespan of the plastic covering can vary depending on the quality of the material and exposure to UV radiation, but it can often be replaced. The internal environment can be further managed with heating, irrigation, and shading systems to optimize conditions for specific plant species.
