If you are growing carnations under a protected environment for good quality, the Polyhouse/greenhouse construction should be kept as simple as possible by meeting required conditions for the right climate. The plastic greenhouse should be constructed to have 3 to 4 m3 of airspace per m2 of the floor surface. This should be equal to a gutter height of 2.5 meters to 3.5 meters as a minimum. Avoid too low greenhouse constructions as there will be high air humidity and high temperature. Don’t construct too large Polyhouse/greenhouse under one roof as this crop requires good sunlight (ventilation) and climate control. The roofing material could be Low-Density Polyethylene and should be replaced once in 3 years.
