Izitshalo eziningi zidinga ukukhanya ukuze zikhule ngoba ukukhanya kubalulekile ku-photosynthesis.Ngaphandle kwawo, izitshalo azikwazanga ukwenza ukudla.Kodwa ukukhanya kungase kuqine kakhulu, kushise kakhulu, noma kuhlale isikhathi eside ekukhuliseni izitshalo ezinempilo.Ngokuvamile, ukukhanya okwengeziwe kubonakala kungcono.Ukukhula kwezitshalo kuyashesha ngokukhanya okukhulu ngoba amaqabunga amaningi esitshalo ayachayeka;okusho ukuthi i-photosynthesis eyengeziwe.Eminyakeni emibili edlule ngashiya ama-planter amabili afanayo endaweni ebamba ukushisa ebusika.Omunye wabekwa ngaphansi kokukhanya okukhanyayo kanti omunye akafakwanga.Ngentwasahlobo, umehluko wawumangalisa.Izitshalo ezisesitsheni esingaphansi kokukhanya bezicishe zibe zinkulu ngo-30% kunalezo ezingakutholi ukukhanya okwengeziwe.Ngaphandle kwalezo zinyanga ezimbalwa, lezi zitsha ezimbili bezilokhu zihlangene.Ngemva kweminyaka kusabonakala ukuthi yisiphi isiqukathi esasingaphansi kokukhanya.Isiqukathi esingatholanga ukukhanya okungeziwe sinempilo ngokuphelele, sincane nje.Nokho, ngezitshalo eziningi, izinsuku zasebusika azinde ngokwanele.Izitshalo eziningi zidinga amahora angu-12 noma ngaphezulu okukhanya ngosuku, ezinye zidinga amahora angu-18.
Ukwengeza izibani ezikhulayo ku-greenhouse yakho kuyindlela enhle kakhulu uma uhlala eNyakatho futhi ungakutholi amahora amaningi emini yasebusika.Izibani zokukhula ziyinketho enhle kakhulu yokushintsha eminye imisebe engekho.Mhlawumbe awunayo indawo eseningizimu ekahle endaweni yakho ye-greenhouse.Sebenzisa izibani ezikhulayo ukuze wengeze ubude bosuku kanye nekhwalithi nokuqina kokukhanya.Uma ikhava yakho ye-greenhouse ingasakazi kahle ukukhanya kwelanga, ungangeza izibani ukuze ugcwalise ithunzi ukuze ukhule ngokwengeziwe.
