Miedzo iyi yakaitwa panguva imwe chete munguva yechando, imwe mugreenhouse ine HID toplighting, imwe mugreenhouse ine LED toplighting, uye imwe mupurazi reguta rine mwenje we LED. Zvirimwa zvakafanana zve lettuce nefetereza imwe chete zvakashandiswa muzviyedzo zvese zviri zvitatu. Zvirimwa mupurazi reguta kunyanya, zvaive nemazinga akaderera e nitrate, nekuti zvakarimwa zvakangofanana nehuwandu hwechiedza zuva rega rega.
Zvirimwa zvakarimwa mugreenhouse pasi peHID uye LED zvese zvaive nemazinga epamusoro enitrate nekuti aikanganiswa nemamiriro ekunze akasiyana uye mashoma emwenje mwero pane optimum. Zvirimwa zvakasangana nemakore, zuva, kutonhora uye kudziya kwemazuva, panguva iyo nitrate yakaungana mumashizha emiti. Mhedzisiro yekuedza uku yakasimbisa kuti kunze kwekuvhenekesa kwe LED, mamiriro ekunze chinhu chakakosha chekutonga kuti uwedzere kuderedzwa kwe nitrate.
Pazvirimwa zvakawanda zve lettuce, isingasviki 1500 mg/kg ye nitrate inogona kuwanikwa nekungogadzirisa resipi yemwenje mukati menzvimbo yakapihwa yekukura. Izvi hazvina kukanganisa goho kana zvimwe zvemhando, sehupenyu hwesherufu uye zvemukati zvevhitamini. Kubatanidza resipi yakareruka neine simba rekudiridza kunogona kudzikisa mazinga aya kana zvichidikanwa. Imwe nzira yakafanana inogona zvakare kushandiswa mugreenhouse inoshandisa mwenje wekuwedzera we LED nekugadzirisa mamiriro ekunze uye mwenje kuti ushande pamwechete. Muyedzo yegreenhouse ine mwenje we LED, takawana yakaderera nitrate mazinga pane muyedzo mugreenhouse ine HID mwenje.
