Successful use of polythene and glass greenhouses

Za uspješno korištenje klijališta, staklenika ili plastenika tokom cijele godine potrebno ih je u našim klimatskim uvjetima zimi grijati, a ljeti hladiti. Grijanjem tla postižemo da biljka može dobro rasti i u hladnijem zraku, jer joj korjenov sustav nije pothlađen. Rashlađivanjem zraka hlapljenjem vode pružamo biljkama korisnu zaštitu, te omogućavamo njihov uspješan uzgoj tokom ljetnih vrućina.In order to use glass or polythene greenhouses and forcing-beds successfully throughout a year, it is neccessary to warm them in winter and cool them in summer in Croatian climate conditions. By warming the soil a plant can grow well even if the air is colder, because the root system has not grown cold. By cooling the air by evaporating water we give a useful protection to the plants, and make their growing throughout the summer heats successful
