E pili ana i ka DFT Floating Hydroponics
ʻO DFT (Deep flow technique) ʻo ia ke ʻano kumu mua loa o ka ʻōnaehana hydroponic, e pili ana i kahi ʻenehana hydroponic kahi e ulu ai ka ʻōnaehana kumu o ka mea kanu i kahi papa momona hohonu a kahe. Hoʻopiha ʻia ka pahu kanu me kahi o 5 a 10 cm a i kekahi manawa ʻoi aku ka hohonu o ka ʻawaʻawa, e waiho ana i ka ʻōnaehana kumu o ka mea kanu i loko, ʻoiai e hoʻohana ana i ka paila wai i waena o ka wehe ʻana i ka wai hoʻolako e hoʻoheheʻe i ka wai meaʻai, e hoʻohui. ka oxygen i loko o ka meaʻai meaʻai a hoʻonui i nā meaʻai i loko o ka meaʻai.
'O kēia 'ano o ka mahi 'ana i ka nutrient sour layer nutrient seifrom he 'ano pa'a, akā, ho'oponopono pū i ka pa'akikī e pono ai i ka 'ōnaehana mo'omeheu wai 'ai mea 'a'ole hiki ke hana pono.
ʻO DFT (Deep flow technique) kahi ʻano o ka hydroponic gradening kahi e uhi ʻia ai nā mea kanu i nā moena pāpaʻu, a kahe mau ka hopena meaʻai ma luna a puni nā aʻa o nā mea kanu.
Nā hiʻohiʻona o ka ʻenehana moʻomeheu wai wai hohonu

Hōʻike ʻo Deep i ka pahu kanu ponoʻī i loaʻa ka wai puna ponoʻī he hohonu, a hohonu ka papa wai meaʻai i loko o ka pahu kanu.Hiki ke hoʻonui ʻia ka ʻōnaehana kumu i loko o kahi hopena meaʻai hohonu, ʻoi aku ka nui o nā meaʻai i loko o ka ʻōnaehana kanu holoʻokoʻa, ka hoʻohui ʻana o ka hopena meaʻai, ka hoʻopaʻa ʻana (me ka ʻike ʻana o nā meaʻai like ʻole, ka nui o ka paʻakai a me ka hoʻoheheʻe ʻana o ka oxygen i loko o ka meaʻai. solution), acidity, moisture and temperature, etc. ʻaʻole i maʻalahi ke hana i nā loli koi, paʻa mau ke ʻano o ka ulu ʻana o ka ʻōnaehana kumu, kūpono ka meaʻai meaʻai a me ka hoʻoponopono He mea nui kēia o ka ʻenehana aʻo wai wai hohonu.

3. Hoʻokuʻu ʻiaʻO ka hoʻokuʻu ʻana e pili ana i ke kau ʻana o kahi mea kanu i kanu ʻia ma luna o ka ʻili o ka wai meaʻai, me ka manaʻo o:(1) E hoʻokaʻawale i ka ʻāʻa aʻa mai ka ʻili wai a pale aku i ka hoʻokomo ʻia ʻana o ka ʻāʻa aʻa i loko o ka wai hoʻoheheʻe a hiki i ka pohō a i ʻole ka make (koe wale nā mea kanu a me nā mea kanu me ka ʻiʻo hoʻokomo oxygen mai ka lepo a i ka lepo);(2) E hoʻomaikaʻi i ka hāʻawi ʻana i ka oxygen o ka ʻōnaehana kumu: hiki ke hoʻonui ʻia kahi ʻāpana o ka ʻōnaehana kumu i loko o ka hopena meaʻai e ulu ai, aʻo ka ʻaoʻao ʻē aʻe e hōʻike ʻia i ka ʻili wai meaʻai ma waena o ka pā paʻa a i ʻole ke ʻano mesh paʻa o ka. ʻāpana o ka ea maʻemaʻe, i hiki ai i ka ʻōnaehana meaʻai a me ka ʻōnaehana kumu i ka lewa ke komo i ka oxygen. i ka ulu ʻana o ka hua a me nā kūlana climatic e hoʻoponopono i ka absorption o ka oxygen mai ka ʻōnaehana kumu.
ʻO ka maikaʻi o ka hydroponics
1. E hoola i ka aina. Hiki iā mākou ke kanu i nā wahi a pau, ʻo ka luna hoʻi.
2. E mālama i ka wai 85%.
3. E hoola i ka hana.
4. Mālama i ka fertilizer 80 % .
5. E mālama i ka pesticide, aloha o ke kaiapuni.
6. Hana kiʻekiʻe.
7. ʻO ka lokahi huahana. Liʻiliʻi ʻōpala.
8. Ke kūlana kiʻekiʻe a me ka palekana.
9. Hiki ke hoʻomaluʻia nā kūlana ulu a pau.
