He roa te roa o te mahi o te miihini miihini hau, a ka nui te waahi rokiroki mamaoa o ana taputapu, kia tere ai te whakataurite i nga huringa kawenga me te whakapai tonu i te kounga o te mamaoa maroke ki tetahi whānuitanga.Na te mea he pai te mamaoa maroke mo te whakakore i te hauhautanga kore.Ma tenei ka whakaora i te kohi wahie, ka whakaiti i te pakaru o te punaha, ka roa te ora o te ratonga.
Ko te hanga o nga miihini korowha pupuhi hau he tino paerewa me te tino pai ki te taiao.I roto i te tukanga o te whakawhanaketanga me te whakamahi, ka hangaia kia rite ki ona paerewa e tika ana me nga paerewa ahumahi.I te nuinga o te waa he punaha whakapumautanga o te kounga pai me te tukanga whakaputa tino pai, ka taea te whakarite i te haumaru me te pumau o te hua ki tetahi waahanga.
He nui te ruuma pararihi o te miihini hiko wahie, ka taea te whakamahi katoa i tana whakawhitinga wera radiation, ka taapirihia he kaitahu kawemai i te wa e mahi ana, kia taea ai te whakahoki mai i te wahie ki te taumata e rite ana..Ka whakaitihia e te mura te tukunga o nga waahanga kino i roto i te hau rewharewha.
