LED 400W Pae Kotahi atamai tupu marama

Ko te PAR (photosynthetically effective radiation) e whakaatu ana i te wahanga o te awhiowhio kitea (400 nm-700 nm) ka "kite" nga tipu ka whakamahia mo te whakaahua.Ko te PPFD (Photosynthetic Photon Flux Density) te ine i te nui o te marama (PAR) ka riro i te tipu i roto i te waa.Ko te PPFD te tohu mo te kiato o te marama ka riro mai i nga tipu i roto i te waa, ka ine ki te micromolars mo ia mita tapawha mo ia hekona [photon]

He aha te PAR me te PPFD i roto i nga rama tipu LED

Ko tetahi huarahi ki te whakaata i te PPFD ko te whakaaro kei te "ringi" te ra ki runga i nga rau tipu.I te whitinga o te ra ki runga i nga tipu, kei te kohi kaha o ratou rau.

Ko te PPFD he inenga mo te nui o te marama (whakaahua) ka "ringihia" e te ra ki runga i nga tipu i roto i te waa.He tohu nui te PPFD na te mea ka awhina nga kaiahuwhenua ki te ine tika i te kaha o te marama o te photosynthesis i roto i te kohao.He mea nui ano hoki tenei na te mea ko nga rama e tata rawa ana ki te tuanui ka puta te wera, te whakapoipoi, te whakaheke tipu, te pahekeheke ranei.
