Iphrojekthi enamandla yomncintiswano wesayensi ye-hydroponics empeleni iyisivivinyo esinobulungiswa: ushintsha into eyodwa, ugcine konke okunye kunjalo, bese ukala okwenzekayo. I-hydroponics ikufanele kahle lokhu ngoba izimo zokukhulisa ziyizinombolo ozibekayo, hhayi isimo sezulu osilindayo. Amahora okukhanya, amandla omsoco, ibanga phakathi kwezitshalo nomoya-mpilo — konke kusezandleni zakho. Ngezansi kunamadizayini ayisishiyagalombili esivivinyo esinobulungiswa ongawenza esitendeni sefasitela noma erakini elincane, kanye nendlela yokurekhoda nokudweba idatha ukuze imiphumela yakho imelane nemibuzo yomahluleli.

Okuthathu okuguqukayo okudingwa yizo zonke izivivinyo ezinobulungiswa

Ngaphambi kokuba kufakwe ngisho nembewu eyodwa, bhala phansi izinhlobo ezintathu zalokho okuguqukayo. Ukukwenza kahle lokhu yikho okwehlukanisa iphrojekthi yesayensi nomboniso wezitshalo wasengadini.

• Okuguqukayo okuzimele yinto eyodwa oyishintsha ngamabomu, njengamahora okukhanya ngosuku.
• Okuguqukayo okuncikile yilokho okukalayo njengempendulo: ubude, inani lamaqabunga, noma isisindo esimanzi ngesikhathi sokuvuna.
• Okuguqukayo okulawulwayo yikho konke okugcina kufana ukuze ushintsho lube nobulungiswa: izinga lokushisa lamanzi, i-pH, iqoqo lembewu, isisekelo sokukhulisa nevolumu yethangi lamanzi.

Sebenzisa okungenani amaqembu amabili noma amathathu okuhlolwa, futhi usebenzise izitshalo ezintathu eqenjini ngalinye. Izitshalo ezintathu zikuvumela ukuthi ususe umthelela wesithombo esibuthakathaka ngokuthola isilinganiso, okuwumehluko phakathi kwenhlanhla nomphumela wangempela. Ithemu eyodwa ngokuvamile yisikhathi esanele ezitshalweni ezikhula ngokushesha njenge-letisi, i-basil, isipinashi noma ama-microgreens.

Ukuhlolisisa okuyisishiyagalombili ongakwenza ngempela

Umugqa ngamunye ushintsha into eyodwa kuphela eguqukayo. Khetha okukodwa, futhi umelane nesifiso sokuhlola izinto ezimbili ngasikhathi sinye, ngoba khona-ke ngeke ukwazi ukusho ukuthi yikuphi okubangele ushintsho.

Ukuhlolisisa	Okushintshayo	Okukalayo	Okugcina kufana
Amahora okukhanya	Ukukhanya kwansuku zonke, isb. amahora angu-12 vs 16 vs 20	Ubude nenani lamaqabunga	Ibanga lokukhanya, i-EC, izinga lokushisa
Amandla omsoco	I-EC yesixazululo: ephansi, emaphakathi, ephezulu	Isisindo esimanzi ekuvuneni	I-pH, amahora okukhanya, isisekelo sokukhulisa
I-pH	I-pH yesixazululo, isb. 5.0, 6.0, 7.0	Umbala wamaqabunga nesisindo	I-EC, ukukhanya, izinga lokushisa
Ibanga phakathi kwezitshalo	Isikhala phakathi kwezitshalo emseleni	Isisindo esitshalweni ngasinye	Ukukhanya, umsoco, isitshalo
Ukungeniswa komoya	Impompo yomoya ivuliwe vs ivaliwe	Ubude bezimpande nombala	Umsoco, izinga lokushisa, ukukhanya
Izinga lokushisa lamanzi	Ithangi elipholile vs elifudumele	Ukukhula ngesonto	I-EC, i-pH, amahora okukhanya
Umbala wokukhanya	Ama-LED amhlophe vs abomvu-naluhlaza	Ubude nesikhala samaqabunga	Isamba samahora okukhanya, ibanga
Isisekelo sokukhulisa	I-rockwool vs amatshana obumba vs i-coco coir	Isikhathi sokuhluma nobude	Umsoco, ukukhanya, izinga lokushisa

Izibalo ze-EC, ze-pH nezokukhanya ezingenhla ziyizindawo zokuqala zendlela yakho, hhayi izimpendulo okufanele uzilindele. Umsebenzi wakho ukuthola okwenzeka ngempela bese ukubika ngobuqotho, ngisho noma izitshalo zingavumelani nombono wakho ohlolwayo.

Ukukala nokudweba igrafu yedatha yakho

Abahluleli banika amaphuzu amaningi kakhulu kugrafu kunesithombe esisodwa sokuphela kwephrojekthi. Yenza ukukala okufanayo ngosuku olufanayo isonto ngalinye, futhi urekhode izinombolo eziqondile kunokuthi “sibukeka side”. Irula nesikali sasekhishini kwenele ubude nesisindo, kanti ipeni eliyisisekelo le-EC ne-pH lenele isixazululo.

Ezibalweni ezishintshashintsha usuku lonke, njengezinga lokushisa, i-EC nezinga lokukhanya, i-microcontroller iyazikhokhela. Ibhodi elinjenge-sheenbot∞ lingafunda iprobhu bese lirekhoda inani njalo emizuzwini embalwa, okuguqula ukuqagela kwakanye ngesonto kube ngumugqa ofanele kugrafu. Abafundi bavame ukwakha uhlelo lwabo lokuqala lokurekhoda izinzwa kwelinye lamawekhishophu ethu amaholidi esikole, futhi ibhodi namaprobhu ayatholakala esitolo uma ufuna ukuzimisela elakho ekhaya.

Izinhlobo ezimbili zamagrafu zanele emaphrojekthini amaningi: igrafu yomugqa yokukala ngokuhamba kwesikhathi, yokukhula isonto nesonto, negrafu yamabha eqhathanisa umphumela wokugcina kuwo wonke amaqembu okuhlolwa, yesisindo ngaphansi kwamahora angu-12, angu-16 nangu-20 okukhanya. Beka amalebula anezinyunithi kuma-eksisi akho, futhi uphawule noma yikuphi ukucishwa kukagesi. Impompo noma isibani esasicimile amahora amane siyingxenye yedatha yakho, hhayi into okufanele uyifihle.

Uhlaka lokubhala olulindelwe ngabahluleli

Iningi lemibukiso yaseNingizimu Afrika, kuhlanganise ne-Eskom Expo for Young Scientists, lifuna umgogodla ofanayo. Gcwalisa isihloko ngasinye ngokulandelana:

1. Inhloso: umusho owodwa ngalokho okuhlolayo.
2. Umbono ohlolwayo: isibikezelo sakho nesizathu saso, kubhalwe ngaphambi kokuba uqale.
3. Indlela: imininingwane eyanele ukuze omunye umuntu akwazi ukukuphinda ngendlela efanayo ncamashi, kuhlanganise nalokho okulawulayo.
4. Imiphumela: ithebula lakho namagrafu, kanye nomugqa noma emibili echaza ukuthi kukhombisani.
5. Ingxoxo: ukuthi idatha isho ukuthini, yini engahambanga kahle, nokuthi yini obungayishintsha.
6. Isiphetho: ingabe ubufakazi busekela umbono wakho ohlolwayo? Yebo, cha, noma ngokwengxenye.

Amaphutha avamile okufanele uwagweme

• Ukushintsha izinto ezimbili eziguqukayo ngasikhathi sinye, ngakho ayikho imbangela eyodwa engahlukaniswa.
• Isitshalo esisodwa eqenjini ngalinye lokuhlolwa, okukushiya ungenayo indlela yokuthola isilinganiso.
• Ukukala ngeso esikhundleni sokurekhoda izinombolo.
• Ukugcwalisa ithangi ngaphandle kokuhlola i-EC ne-pH, okushintsha buthule izinto zakho eziguqukayo ezilawulwayo.
• Ukuqala sekwephuze kakhulu. Ukuhluma nokuhlolwa okunobulungiswa kudinga amasonto ambalwa, ngakho qala ekuqaleni kwethemu.

Okumele ukuthathe

Amaphrojekthi e-hydroponics angcono kakhulu alula: into eyodwa ecacile eguqukayo, ukukala okuqotho, negrafu exoxa indaba. Yenza kahle isivivinyo esinobulungiswa bese ngisho nesitende sefasitela esinamaletisi siba yisayensi yangempela. Uma ufuna usizo lokuguqula elinye lala madizayini libe yinto oyakhayo, bhukha ikilasi lokuzama bese sikusiza uhlele umshini nokurekhodwa kwedatha.

Imibuzo evame ukubuzwa

Kufanele ukuhlolisisa kuthathe isikhathi esingakanani?

Hlela amasonto amane kuya kwayisithupha okukhula ngemva kokuhluma. Leso yisikhathi eside ngokwanele ukuze ubone umehluko wangempela phakathi kwamaqembu okuhlolwa nokuze ubeke amaphuzu amaningana kugrafu, futhi singena ethemini elilodwa lesikole.

Yikuphi ukuhlolisisa okulula kakhulu kumuntu okwenza okokuqala?

Amahora okukhanya noma amandla omsoco. Kokubili kulula ukukulawula, kushibhile ukukumisa, futhi ngokuvamile kukhombisa umehluko ocacile, okugcina usosayensi omncane ekhuthele.

Ngabe ngidinga izinzwa ezibizayo?

Cha. Irula, isikali nepeni eliyisisekelo le-EC ne-pH kwanele emaphrojekthini amaningi. Ukurekhoda okuzenzakalelayo nge-microcontroller kuyinzuzo eyengeziwe eyenza amagrafu akho acebe, hhayi isidingo somphumela oqinile.
