In tropical and subtropical regions of high rainfall, the protection against the rain becomes, in
many cases, the main purpose of using greenhouses.

The vicinity of the sea provides good temperature conditions for greenhouse cultivation in
Mediterranean coastal areas.
good light conditions which induced a
product of better quality (Nelson, 1985;
Wittwer and Castilla, 1995). Afterwards,
Colombia partially displaced some carna-
tion growers, due to its lower growing costs
and their good quality (due to the climate
conditions), despite the high transport
costs to the North American markets. The
displacement of the production areas to
regions with milder climate has enabled
the use of less sophisticated greenhouses
and therefore, those of cheaper construc-
tion which enabled production at more
competitive costs (Castilla
et al
., 2004).
