He mea nui te pūnaha hauhautanga o te whare kati kōtuhi ki te hauora o ngā tipu me te whakaputa hua. He tokomaha ngā māra tauhou kāore e kī ana he puhoi te tipu, he iti ngā hua, he raruraru rānei ki ngā mate urutā nā te koretake o te pūnaha hauhautanga o te whare kati kōtuhi. E mārama ana te nuinga o ngā māra ki te hiranga o ngā pūnaha hauhautanga hei whakahaere i te pāmahana engari he maha ngā painga e puta mai ana i ngā pūnaha hauhautanga. Ehara i te mea he mea nui noa iho ngā pūnaha hauhautanga hei pupuri i ngā āhuatanga taiao engari he pānga tika hoki ki te kaha o te tipu ki te mahi i te photosynthesis, te tango i ngā mea nui, me te whakaoti i ngā huringa whakaputa uri (whakawhitiwhiti). E whā ngā mahi nui a ngā pūnaha hauhautanga whare kati kōtuhi: te whakahaere pāmahana, te whakahaere haumākū, te whakakapinga CO2/hāora, me te tohanga o te hau.
