**2.1 Site microclimate**

At different geographical latitudes and longitudes, the climatic conditions may differ substantially, and certain factors may even pose limitations for vegetable crop growing—insufficient daylight intensity, frequent fogs, extremely bad weather conditions, too much shade from trees, or high mountains, etc. Such outdoor climatic conditions are unfavorable for growing most of the vegetable crop varieties, which means that it would require substantial investments in indoor installations if one would opt for building a greenhouse in such a location. One of the most important factors is the wind rose chart. One should gather all the data from a relevant hydro-meteorological service for a larger number of years (up to 30, and if the data can be obtained, it would be best to get it for many years, even up to a 100, so as to know what the microclimatic extremes could expected in a given area).
