Tukanga Whakaputa
Ko te tukanga o te hanga hiko teitei (HP) karaehe kauwhata hiko he maha nga waahanga.Tuatahi, ka ata whiriwhirihia nga rauemi mata, me te whakarite he tino kounga.Ka konatunatuahia te tiihi hinu, te tiihi ngira, me te uku waro ki te tauwehenga kua whakaritea.Ka tukatukahia te ranunga ki te hanga i tetahi poraka kaakaariki, katahi ka tukuna ki te mahi whakangao.Ko tenei tukanga ko te whakamahi i tetahi momo pitch motuhake, i hangaia hei whakauru i te poraka matomato me te whakapakari.I muri i te impregnation, ka tunuhia te poraka matomato i roto i te taiao whakahaere hei hanga i te hiko hiko.
