Izivivinyo zenziwa ngesikhathi esifanayo ebusika, eyodwa e-greenhouse enokukhanyisa okuphezulu kwe-HID, enye i-greenhouse enokukhanyisa kwe-LED, kanti enye epulazini ledolobha elinezibani ze-LED. Izitshalo ezifanayo ncamashi zikalethisi kanye nomanyolo ofanayo kwasetshenziswa kuzo zontathu izivivinyo. Izitshalo ezisepulazini lasedolobheni ikakhulukazi, zazinamazinga aphansi kakhulu e-nitrate, ngoba zazilinywa ngokuqhubekayo nenani elifanele lokukhanya nsuku zonke.
Izitshalo ezitshalwa ku-greenhouse ngaphansi kwe-HID ne-LED zombili zazinamazinga aphezulu e-nitrate ngoba zithintwa izimo zezulu ezihlukene kanye namazinga okukhanya amancane kunokwanele. Izitshalo zaba nezinsuku eziguqubele, libalele, zibande futhi zifudumale, lapho ama-nitrate anqwabelana emaqabunga ezitshalo. Imiphumela yalolu cwaningo iqinisekise ukuthi ngaphezu kokukhanyisa kwe-LED, isimo sezulu siyipharamitha ebalulekile okufanele ilawulwe ukuze kwandiswe ukuncishiswa kwe-nitrate.
Ezitshalweni eziningi zikalethisi, ngaphansi kuka-1500 mg/kg we-nitrate kungafinyelelwa ngokuhlanganisa iresiphi yokukhanya ngaphakathi kwendawo yokukhula enikeziwe. Lokhu akuzange kuthinte isivuno noma ezinye izici zekhwalithi, njengempilo yeshalofu nokuqukethwe kwamavithamini. Ukuhlanganisa iresiphi elula nesu lokunisela eliguquguqukayo kungase kwehlise la mazinga uma kudingekile. Isu elifanayo lingasetshenziswa futhi ku-greenhouse esebenzisa ukukhanya kwe-LED eyengeziwe ngokulungisa imingcele yesimo sezulu kanye nokukhanyisa ukuze kusebenze ndawonye. Esivivinyweni se-greenhouse esinezibani ze-LED, sizuze amazinga aphansi e-nitrate kunasesivivinyweni se-greenhouse enezibani ze-HID.
