Shade cloth provides some of the functions of thermal screens. Under extreme, hot conditions, shading reduces the amount of incoming radiation.
This in turn reduces the heat load in the greenhouse and assists in maintaining humidity around the plants and reducing plant stress. The use of shade cloth for cooling is most effective when the material is used outside of the greenhouse. If shade screens are used, pale coloured materials should be selected as these uniformly reflect solar radiation and do not absorb as much heat themselves as darker materials.
A range of products offer shading from 30% up to almost total blackout. Whitewash paints are another shading option that can be applied to reduce the amount of radiation entering the greenhouse. White-wash is a lime wash or diluted paint applied to the outside of the greenhouse covering.
It reduces the amount of solar radiation entering the greenhouse and therefore reduces temperature. The disadvantage of this type of screen is that it is applied seasonally, such as at the beginning of summer and consequently is not be readily adjusted for changing conditions from day to day or during a day.
This results in reduced light levels even when temperature reduction is not needed. The end effect can be quite significant reductions in light levels and consequently yield. There are white wash products available which become transparent when wet so as to allow more light in during rain periods. During warm overcast conditions, these products can be hosed down to increase light transmission.
Insect Nets
Insect nets can be used as the cover material for the net houses, or partly used for the purpose of ventilation and anti-insects. Different meshes are available.
