Thaum yuav khoom high-lub zog LED loj hlob teeb, PPFD (Photosynthetic Photon Flux Density) yog ib qho kev ntsuas uas yuav luag tsis pom. Ntau tus neeg siv khoom nug tib lo lus nug thaum nug txog cov khoom lag luam: "PPFD cov zis ntawm lub teeb no yog dab tsi?" Txawm li cas los xij, PPFD siab dua tsis tas yuav zoo dua, thiab tsis muaj ib tus nqi ruaj khov uas haum rau txhua qhov xwm txheej. Kab lus no tham txog yuav txhais li cas thiab xaiv PPFD qib rau siab - lub zog loj hlob teeb los ntawm qhov kev xav ntawm kev siv tswv yim.
PPFD yog dab tsi, thiab yog vim li cas nws tseem ceeb tshaj wattage?
PPFD (Photosynthetic Photon Flux Density) yog hais txog tus naj npawb ntawm photosynthetically active photons ncav cuag cov nroj tsuag canopy ib cheeb tsam ntawm ib chav tsev ntawm lub sij hawm; Nws ntsuas hauv μmol / m² / s.
Wattage qhia tsuas yog lub hwj chim noj ntawm lub fixture, tsis yog tus nqi ntawm usable photons tau txais los ntawm cov nroj tsuag.
Ob lub teeb 600W tuaj yeem muaj qhov sib txawv ntawm PPFD ntau yam nyob ntawm lawv lub teeb pom kev zoo (PPE).
Yog tias koj saib tsuas yog wattage yam tsis tau kuaj xyuas PPFD daim ntawv qhia kev faib khoom thaum lub sijhawm yuav khoom, koj pheej hmoo yuav cov khoom nrog "inflated" lossis kev ntsuas lub zog tsis raug.
Yog li ntawd, rau siab - lub hwj chim fixtures, ntsuam xyuas PPFD nrog rau cov cheeb tsam thiab lub teeb uniformity yog tus yuam sij rau kev txiav txim seb lub teeb puas tiag tiag siab - zoo thiab zoo.
Pom zoo PPFD ntau yam rau ntau theem kev loj hlob
Cov nroj tsuag muaj qhov sib txawv ntawm qhov yuav tsum tau siv lub teeb ntawm ntau theem kev loj hlob -ib qho taw tes feem ntau saib los ntawm ntau tus neeg siv khoom.
Seedling / txiav theem:Feem ntau pom zoo ntawm 100-300 μmol / m² / s; Lub teeb ntau dhau tuaj yeem ua rau photoinhibition hauv cov nroj tsuag.
Vegetative loj hlob theem:Feem ntau ntawm 300-600 μmol / m² / s, nyob ntawm seb hom qoob loo tshwj xeeb.
Flowering/Fruiting theem:Feem ntau siab -teeb- xav tau qoob loo (xws li txiv lws suav, kua txob, thiab qee yam paj ntoo) xav tau 600-1000 μmol / m² / s, lossis siab dua.
Rau qee qhov siab -lub teeb- xav tau cov qoob loo (xws li qee hom cannabis lossis txiv hmab txiv ntoo zaub), PPFD qib tuaj yeem tshaj 1000 μmol / m² / s thaum muab CO2 ntxiv.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov nuj nqis no sawv cev rau kev siv ntau yam kev lag luam. Qhov txiaj ntsig zoo tshaj plaws yuav tsum tau hloov kho raws li DLI (Txhua Hnub Teeb Nruab Nrab) thiab cov nroj tsuag tshwj xeeb; tus lej siab dua tsis yog ib txwm zoo dua.
Yam tseem ceeb cuam tshuam rau qhov tseeb PPFD tso zis
PPFD ntsuas rau tib lub teeb pom kev zoo tuaj yeem sib txawv hauv cov xwm txheej sib txawv -ib qho xwm txheej tshwm sim thaum kuaj.
Hanging qhov siab:Qhov ze dua qhov kev sib tw yog rau cov nroj tsuag, qhov siab dua ntawm PPFD, txawm hais tias qhov kev pab them nqi qis dua.
Lub teeb lub kaum sab xis thiab lub teeb pom kev tsim: Siv tau zoo thib ob optics tsom rau photons ntawm lub hom phiaj loj hlob tsis yog nkim lawv ntawm qhov chaw.
Chip degradation:LED chips muaj teeb pom kev zoo dua lub sijhawm; qhov no piav qhia vim li cas qee lub teeb zoo li "tsawg ci" tom qab siv ntev.
Reflective ib puag ncig:Cov khoom siv ntawm cov tsev pheeb suab loj loj (xws li, aluminized zaj duab xis) cuam tshuam rau kev siv photon efficiency; tib lub teeb yuav ua rau cov ntawv nyeem PPFD sib txawv hauv cov tsev pheeb suab sib txawv.
Qhov no yog vim li cas cia siab rau ib qho chaw tsim khoom lub ncov PPFD daim duab yog txwv tus nqi; Nws yog qhov zoo dua los sab laj PPFD daim ntawv qhia kev faib tawm los ntsuas lub teeb pom kev zoo thoob plaws thaj chaw loj hlob.
Kev txiav txim siab xaiv High-Power Grow Lights
Raws li cov ntsiab lus saum toj no, peb feem ntau ua raws cov lus pom zoo rau cov neeg siv khoom los ntawm cov ces kaum hauv qab no:
Txheeb xyuas cov qoob loo thiab kev loj hlob ua ntej txhawm rau txiav txim siab PPFD qhov xav tau, tsis yog tsuas yog caum "tus lej siab."
Tshawb xyuas seb cov chaw tsim khoom puas muab cov thib peb -peb tau lees paub PPFD daim ntawv qhia kev faib tawm es tsis yog tus nqi siab tshaj plaws xwb.
Tsom ntsoov rau thaj tsam ntawm kev them nyiaj thiab kev sib koom ua ke; Txawm hais tias lub teeb muaj qhov chaw siab nyeem ntawv, qhov poob loj heev - tawm ntawm cov npoo yuav cuam tshuam tag nrho cov txiaj ntsig loj hlob.
Factor nyob rau hauv dai qhov siab rau qhov tseeb xam; PPFD cov zis ntawm tib lub teeb tuaj yeem sib txawv los ntawm ntau tshaj ob npaug nyob ntawm qhov siab.
Cov ntsiab lus
PPFD yog ib qho kev ntsuas tseem ceeb rau kev txiav txim siab seb qhov siab - lub zog loj hlob li cas raws li qhov xav tau kev cog qoob loo, tab sis nws yuav tsum tsis txhob saib hauv kev sib cais. Nws yuav tsum tau soj ntsuam nrog rau tej yam xws li theem kev loj hlob, cheeb tsam kev pab them nqi, dai qhov siab, thiab lub teeb uniformity. Rau cov neeg yuav khoom, ntau dua li kev xav txog "peak PPFD," nws yog qhov tseem ceeb dua los nug, "Dab tsi yog qhov nruab nrab PPFD thiab qib sib xws rau kuv qhov tshwj xeeb loj hlob thiab dai qhov siab?"
Txoj kev no muab cov ntaub ntawv siv tau ntau dua thiab muaj txiaj ntsig. Yog tias koj tab tom xaiv cov cuab yeej siv rau ib txoj haujlwm cog qoob loo lossis xav paub qhov tseeb PPFD kev ua tau zoo ntawm qhov tshwj xeeb siab - lub zog loj hlob lub teeb raws li koj qhov chaw loj hlob thiab dai qhov siab, thov hu rau peb. Peb tuaj yeem muab cov kev daws teeb pom kev zoo thiab cov ntaub ntawv pom zoo raws li koj hom qoob loo thiab ib puag ncig kev cog qoob loo.
