1. Polyhouse is the construction under controlled environment.
2. The polyhouse can be made of transparent, tight, cheap and flexible polythene.
3. In these houses vegetables and other crops can be grown in any season of the year depending upon their requirement, because temperature and humidity can easily be controlled in Polyhouses.
4. Polythene presents the thermal radiation, which increases the temperature and energy and thus helps in the process of photosynthesis. It is well established that for the production of energy vegetable, fruits and flower crop, the polyhouses are constructed with the help of ultraviolet plastic sheets, so that they may last for more than 5 years.
5. The structure is covered with 1501-micron thick plastic sheet. The structure is prepared with the bamboos or iron pipes.
6. Iron pipe structure is costly but more durable than bamboo.
