Pab kom lub paj ntawm cov nroj tsuag muaj lub teeb ci: Txhawm rau kom induce flowering, deb-liab lub teeb ntsiab lus ntawm 730 nm yog xav tau. Yuav siv tau los kho lub photoperiod ntawm cov nroj tsuag. Qee cov nroj tsuag tsuas yog tawg thaum nruab hnub tsawg dua 12 teev. Qee qhov tsuas yog qhov sib txawv, tsuas yog tawg thaum ib hnub dhau 12 teev.
Kev faib tawm spectral: Siv 20 feem pua dub xiav LED (450 nm), 60 feem pua ntawm super liab LED (660 nm) thiab 20 feem pua ntawm cov liab LED photon flux ratio (730 nm).
