Mayeserowo adachitika nthawi yomweyo m'nyengo yozizira, imodzi mu wowonjezera kutentha wokhala ndi zowunikira za HID, imodzi mu wowonjezera kutentha wokhala ndi kuyatsa kwa LED, ndi imodzi mufamu yamzinda yokhala ndi kuyatsa kwa LED. Mbewu zomwezo za letesi ndi fetereza yemweyo zidagwiritsidwa ntchito m'mayesero onse atatu. Mbewu mufamu yamzindawu makamaka, zinali ndi milingo yotsika kwambiri ya nitrate, chifukwa idakulitsidwa nthawi zonse ndi kuwala koyenera tsiku lililonse.
Mbewu zomwe zimabzalidwa mu wowonjezera kutentha pansi pa HID ndi LED zonse zinali ndi nitrate yambiri chifukwa zimakhudzidwa ndi nyengo zosiyanasiyana komanso kuwala kochepa kusiyana ndi momwe zilili bwino. Zomera zinkakumana ndi mitambo, dzuwa, kuzizira komanso kutentha masiku, pomwe nitrate amasonkhana m'masamba a zomera. Zotsatira za kuyesera uku zinatsimikizira kuti kuwonjezera pa kuyatsa kwa LED, nyengo ndizofunikira kwambiri kuti zithetse kuchepetsa kuchepetsa nitrati.
Pa mbewu zambiri za letesi, zosakwana 1500 mg/kg za nitrates zitha kupezeka pokonza njira yowunikira mkati mwa malo omwe akukula. Izi sizinakhudze zokolola kapena zinthu zina zabwino, monga nthawi ya alumali ndi mavitamini. Kuphatikiza njira yopepuka yothirira ndi njira yothirira yosunthika kumatha kuchepetsa milingo iyi ngati ingafune. Njira yofananayi ingagwiritsidwenso ntchito mu greenhouse yomwe imagwiritsa ntchito kuyatsa kowonjezera kwa LED posintha magawo anyengo ndi kuyatsa kuti zigwire ntchito limodzi. Mu kuyesa kwa greenhouse ndi kuyatsa kwa LED, tidapeza milingo yotsika ya nitrate kuposa muyeso mu wowonjezera kutentha wokhala ndi kuyatsa kwa HID.
