Why choose plastic tunnel greenhouse
Plastic tunnel greenhouses can extend the growing period of plants by 3 to 9 weeks. You can buy a tunnel greenhouse online or make one yourself with a plastic greenhouse.
Usually, plastic tunnel greenhouses are cost-effective. Hoops and lids are the two main components of a tunnel greenhouse and these materials are low cost. Even a complete plastic greenhouse kit costs less than $300.
The principle of a plastic tunnel greenhouse is similar to that of a cold frame. The temperature inside a clear plastic tunnel greenhouse is affected by the sun and becomes warmer (5 to 20 degrees Fahrenheit higher than the outdoor temperature).
