Ukusetshenziswa okukabili, ukunweba noma ukuhoxisa, lungisa ngokukhululekile isikhala sebha yokukhanya ukuze kwakheke i-PPFD ehlukile (photosynthetic photon flux density) ,indawo ekhavayo ehlukile kanye nokugxilwa kwezinyawo.

Ngemva kokunwetshwa, ukufakwa okuncane okungu-1000W kungu-6 ngo-4ft.

Ngemva kokunwetshwa, ukufakwa okuncane okungu-730W kungu-4 ngo-4ft.

Inani elanele lokukhanya uma kucatshangelwa ukudonsa kwamanzi nokusebenza kahle

~1500+ umol/s endaweni engu-5'x5'

~1100-1500 umol/s endaweni engu-4'x4'

~600-850 umol/s endaweni engu-3'x3'

~275-375 umol/s endaweni engu-2'x2'

Ukumbozwa okwanele kwe-PPFD yesiteji sesitshalo:imifino:300-600umol/m2/s, imbali:600-1000umol/m2/s
