Pono ka nui o nā mea kanu i ka mālamalama no ka mea he mea nui ka mālamalama no ka photosynthesis.Me ka ʻole, ʻaʻole hiki i nā mea kanu ke hana i ka meaʻai.Akā ʻoi aku ka ikaika o ka māmā, wela, a lōʻihi paha no ka ulu ʻana i nā mea kanu olakino.Ma keʻano laulā, ʻoi aku ka maikaʻi o ka māmā.Hoʻomaka ka ulu ʻana o ka mea kanu me ka nui o ka mālamalama no ka mea ʻoi aku ka nui o nā lau o ka mea kanu i ʻike ʻia;ʻo ia hoʻi ka photosynthesis hou aku.ʻElua makahiki i hala aku nei ua haʻalele au i ʻelua mau mea kanu like i loko o ka hale kōmaena no ka hoʻoilo.Ua waiho ʻia kekahi ma lalo o kahi kukui ulu a ʻaʻole kekahi.Ma ka pūnāwai, he mea kupanaha ka ʻokoʻa.ʻO nā mea kanu i loko o ka pahu ma lalo o ke kukui ua aneane 30% ka nui ma mua o nā mea i loaʻa ʻole ke kukui hou.Ma waho aʻe o ia mau mahina, ua ʻaoʻao mau nā pahu ʻelua.Ma hope o nā makahiki, ʻike ʻia ka ipu i lalo o ka mālamalama.ʻO ka ipu i loaʻa ʻole ke kukui i hoʻohui ʻia he olakino maikaʻi, ʻoi aku ka liʻiliʻi.Me nā mea kanu he nui naʻe, ʻaʻole i lōʻihi nā lā hoʻoilo.Pono nā mea kanu he 12 mau hola a ʻoi aʻe paha i ka mālamalama i kēlā me kēia lā, ʻo kekahi e pono ai i ka 18.
ʻO ka hoʻohui ʻana i nā kukui ulu i kāu hale ʻōmaʻomaʻo he koho maikaʻi loa inā noho ʻoe ma ka ʻĀkau a ʻaʻole loaʻa nā hola he nui o ka lā hoʻoilo.ʻO nā kukui ulu kahi koho maikaʻi loa e pani i kekahi o nā kukuna i nalowale.Malia paha ʻaʻohe ou wahi hema kūpono ma kāu waiwai no ka hale kōmaena.E hoʻohana i nā kukui ulu e hoʻonui i ka lōʻihi o ka lā a me ka maikaʻi a me ka ikaika o ka mālamalama.Inā ʻaʻole hoʻopuehu maikaʻi ka uhi ʻana i ka lā, hiki iā ʻoe ke hoʻohui i nā kukui e hoʻopiha i nā aka no ka ulu ʻana.
