Editing Polytunnel (section)

In a tropical climate, temperatures are prone to soar above all normal levels. In such cases, [[Ultrasonic hydroponic fogger|foggers]]/misters are used to reduce the temperature. This does not increase the humidity levels in the poly house as the evaporated droplets are almost immediately ventilated to open air.

High-tech poly houses even have space-heating systems as well as soil-heating systems to purify the soil of unwanted viruses, bacteria, and other organisms.  The recent Indo-Israel collaboration at Gharunda, near [[Karnal]] is an excellent example of Polyhouse farming taking place in a developing country.

If developing countries were to develop a special incentive program solely for fruit-and-vegetable farmers, especially in demographically large nations like India, then the migration rate from rural to urban areas (as well as the loss of horticultural and fruit/vegetable farmers) to urban areas may be reduced.  This brings a huge potential to improve the farming sector, which is key to long-term economic stability. The small polytunnels used by each farmer in each village promote the cultivation of vegetables both on-season and off-season, and would actually help to moderate the market rate for fruit and vegetables in long run, on a year-round basis, and would help to satisfy local market needs.

For example, in India, the inability to grow tomatoes generates price spikes during the monsoon season. This is seen as an ideal time to grow tomatoes in polytunnels, since they provide the ideal climate for the crop. In India, the [[Abhinav Farmers Club]] grows flowers and organic vegetables in polytunnels.<ref name="LM-20120517">{{cite web |url= http://www.livemint.com/Politics/fW2Pw8ziSw8mFsElM8AEnM/Planting-the-seeds-of-prosperity.html |title= Planting the seeds of prosperity |last= Bhattacharyya |first= Pramit |date= 17 May 2012 |work= Livemint.com |access-date= 23 November 2012 |publisher= [[HT Media]]}}</ref>
