Hoʻonui ʻo Clay Pebbles i nā mea kanu e ulu nei nā mea hoʻolaha
1. Ka inoa huahana: ka pālolo i hoʻonui ʻia
LECA (Lightweight Expanded Clay Aggregate) kahi hoʻohui i hana ʻia o ka pā hale hoʻonui i ka awelika 1200 ℃ i ka paona rotary,
ka Hoʻonui ʻia nā hualoaʻa e nā tausani o nā mane liʻiliʻi e like me ka manawa e kū mai ai kēia wela a me ka porosity
e ka lehulehu nā kīʻaha a me nā meli ma kēia mau ʻōhua e like me ke anuanu.
Hoʻohana ʻia LECA i ʻokoʻa ka nui o nā mea hoʻohālike e hoʻohālikelike ʻia me nā kinipōpō māmā maoli a
mai 1917 ua hoʻohana ʻia ma lalo nei inoa inoa like ʻole ma USA a me ʻEulopa mau ʻāina.
2. Ke Kahu Lele ʻO Clay:
Hoʻomaʻamaʻa loa ʻo Clay pebbles i kahi ulu ulu no nā mea kanu a pau. Hāʻawi ia huki kaomi a me ka waiho ʻana o ka umu.Hoʻohana ia e like me ka mulch hoʻonani no nā mea kanu pot, ma nā mea kanu lepo, me he hoʻohui i nā pā i nā ipu, a he pā lalo ma lalo o ka huki.Hoʻohana nui loa ia i ka ulu hydroponic a pH neutral. Mālama nā wai i loko o nā pōhaku i ka wai a hoʻokuʻu i ka wai inā pono hoʻolako i kahi maikaʻi maikaʻi kūlohelohe no ke kūkulu ʻana i aa. Kūpono no nā rosa, nā orchids a me nā ʻano hua a me nā lau ʻai āpau.ʻO ka hoʻomālamalama pālahalaha pālolo, ʻo ia hoʻi i kapa ʻia ka "ulu pōhaku", kūpono no ka ulu ʻana i ka hydroponic o loko no ka mea o kona kūlohelohe.- He māhu lepo pāpaʻomaʻi ʻaʻohe ʻano wai a alkaline paha.
3. Hoʻomaka
He nui nā hoʻomaikaʻi ʻana o LECA no ka mahiʻai a me nā ʻāina, e hoʻohana ia me ka mea e ulu ana i nā ʻōnaehana Hydroponics, a
kāwili ʻia me nā ʻano mea e ulu ai e like me ka lepo a me ka peat e hoʻomaikaʻi i ka holo ʻana, mālama ka wai i nā manawa maloʻo,
hoʻohuihui i nā aʻa i ka wā o ka hau a hāʻawi i nā aʻa me ka piʻi o ka oxygen hāliʻiliʻi e ulu i ka ulu ikaika. Hiki i ka LECA ke kāwili
me ka lepo momona e hiki ai ke hōʻemi i ka nui o nā mea kanu a me nā lepo lepo.
