1.5. Factors Influenc ng the Select on of the Greenhouse Locat on

1.5.1. Ecolog cal Factors
Plants need su table env ronmental cond t ons for the r development. Therefore, when plann ng
a greenhouse, a su table env ronment should be prepared for the plant to be grown.
1.5.1.1. L ght
L ght has an mportant place n the development of green plants. Plants take advantage of
sunl ght wh le perform ng photosynthes s. Plants convert the carbon d ox de n the a r nto
carbohydrates by comb n ng them w th the water n the r content only when there s l ght. In th s
way, wh le prov d ng the food t needs, they also release oxygen for the cont nuat on of l fe. In order
for the plants to develop, the sunbath ng level must be at the des red level n the reg on to be grown.
The amount of sun exposure of each plant dur ng development s d fferent. As the amount
of sun exposure ncreases, plant growth also ncreases. The cho ce of greenhouse locat on s
mportant, espec ally cons der ng that the weather s constantly cloudy dur ng the w nter months.
Our country allows the construct on of greenhouses almost everywhere n terms of sunbath ng.

1.5.1.2. Temperature
The amb ent temperature s very mportant n determ n ng the greenhouse temperature.
Preferr ng places where the w nter months are warm for greenhouse construct on reduces heat ng
costs. In cold seasons, greenhouses need to be heated, espec ally at n ght. In add t on, m cro-cl mate
places are su table areas for sett ng up greenhouses. The temperature needs of greenhouse plants are
also d fferent from each other. Therefore, before nstall ng the greenhouse, t s necessary to know
the temperature requ rement of the plant to be grown.
