Nu, e mai usor sa arunci banii pe fereastra
Asa ma gandeam si eu - produsul ala l-am gasit pe Ebay, insa vine repede ca e vandut din Europa. Probabil ca erau si la noi pe piata ceva produse similare dar nu am stiu dupa ce sa caut.

eu am ales regular pentru ca am vrut sa-mi feresc semintele de respectivul proces despre care nu situ mai nimic..plus ca o vorba din popor spune ca sunt mai bune regular pt out, chiar daca este mai multa munca si nu stii cu cate femele te alegi. Din fericire , sunt nevoit sa-mi schimb spotul.. ceea ce inseamna inca pe atat de muncit. alte gropi , alti pampersi , dar castig cateva ore bune de soare plus ca sunt intr-un loc mult mai ferit , iar sansele ca cineva sa ajunga pe acolo sunt minime. .. voi selecta dupa ochi femelele.. nu am lupa inca si nici nu am vazut preflowers , voi merge la ghici. din cate stiu , femelele sunt mai mici si au si alta forma..orice indiciu pe care mi l-ati putea indica pentru selectarea femelelor este bine primit. voi reveni peste cateva zile cu un update.. cu poze

Vin si eu cu o intrebare:
Are ceva daca dupa ce ai pus semintele la germinat le scoti din servetele le stergi bine si le pui la loc? precizez ca semintele nu au stat mai mult de 2 ore la germinat.
Care sunt sansele sa continue germinarea? Si care sunt sansele sa nu mai germineze daca o sa le pun dinou in servetele? Multumesc anticipat!

Termina la noi Sour Amnesia de la hortilab ?
depinde de ce toamna prinzi, si ce fenotipuri nimeresti. prea multe variabile ca sa te bazezi numai pe acest strain, dupa parerea mea. dar nu costa nimic sa incerci cateva plante, mai ales daca remarci unele mai indica dominante.
daca vrei sa mergi la sigur alege numai pe strainuri sau crossuri ce termina in max 9-10 sapt.

Ma tot uit la kit-uri HPS si am 2 intrebari...
1. Iau un exemplu concret: sunt becuri de 400W care pe langa 58k lumeni mai au si 128k fitolumeni (extream output). Acelasi bec fara astia 128k fitolumeni e la pret jumatate.
Intrebarea mea ce-i cu fitolumenii astia?
2. Sunt HPS-uri dual spectrum care costa mai mult. Ma gandesc ca scopul lor e sa merga si in veg si in inflorire acelasi bec. E de preferat un bec din asta fata de unul dedicat pe 2700 / 6500 K in functie de perioada?
LE:
Desi inainte de a posta am cautat pe net povestea asta cu fitolumeni m-am prins cam greu ca trebuie sa caut phito (cu ph)... chiar si asa informatia se gaseste mai greu.O pun aici pt cei interesati. E luata de pe un site cu orhidee.
Pe scurt ce am inteles eu este ca asta-i un fel de smecherie de marketing... adica 58k lumeni (pt ochiul uman) echivaleaza cu 128k lumeni pt "ochiul" plantelor.
Diferenta de pret (dublu intre "normal" si "extream output") la un bec produs de aceeasi firma si la aceeasi putere vine din un extra 3000 lumeni si probabil din calitate. Varianta ieftina fiind recomandata pt 4-6luni si cea scumpa pt 9-12luni
Daca gresesc va rog corectati-ma.

becurile cu spectru modificat (dublu, etc.) au mai multa lumina necesara plantelor, deci un numar mai mare de lumeni utili. dar pentru o comparatie corecta trebuie sa compari becurile in aceeasi scala, daca nu iti spune si cati fitolumeni are becul de baza, foarte posibil ca povestea asta sa fie marketing pentru a il vinde pe cel mai scump. in acelasi timp pretul este cam exagerat pentru becurile specializate si balasturile digitale necesare pentru a le rula in parametri perfecti, aproape ca ajungi la aceeasi investitie ca in cazul ledurilor..

da hemp, le-am pus la germina si dupa m-am razgandit.
Am cautat si eu, am gasit raspunsul direct de la sursa

LE: De la min 1:45 incolo.
"The standard measurements of light output have traditionally been done through the foot-candle, lumens and lux. They quantify how humans experience the intensity of light, based on the limited sensitivity of the human eye in the yellow/green area of the spectrum (around 550 nm). Plants however use a much wider spectrum for photosynthesis, called the PAR spectrum (Photo-synthetically Active Radiation), ranging from 400-700 nm
Photosynthesis is not driven by brightness of the light according to the human eye or the energy of a photon (which varies for different colors) but purely by the number of photons in the PAR spectrum. You need about eight photons to bind one CO2 molecule. So to quantify potential photosynthesis it is all about the number of photons within the PAR spectrum hitting the plant. This is expressed as Photosynthetic Photon Flux (PPF – total photons emitted from a light source per second) and Photosynthetic Photon Flux Density (PPFD – the number of photons hitting one square meter of surface per second) and it is measured in moles or micromoles (µmol) of photons.
You can measure the number of photons hitting your plant (PPFD) using a quantum meter, predicting the potential photosynthetic capacity of your light.
You can measure the total number of photons emitted by a lamp (PPF)by putting it in an Ulbricht integrating sphere
So where we used to have luminous flux in lumens, we now have PPF in µmol/s, and where we used to have illuminance (light indicent on a surface) in lux, we now have PPFD in µmol/m2/s
Lamps with high lumens output are not necessary high par output lamps: some lamps with lower lumens output have higher micromole output."

Pic27... merci.
Inteleg ideea si e bine ca exista cineva care numara adevaratul nr de fitolumeni care-i da un bec insa daca o firma... GIB sa zicem zice la categoriile mai scumpe de becuri cati fitolumeni da ar fi logic sa zica si la cele ieftine din productia proprie... si pe site-ul lor nu zice.
Cel putin din motivul asta am zis ca e o smecherie de marketing ca lumea sa cumpere becurile mai scumpe.

"The less expensive alternative
The GIB Lighting Flower Spectre HPS is our standard series for all plant lovers wishing to cultivate successfully who still set store by a low initial budget. Ideal too for hobby gardeners, indoor gardeners and for over wintering tropical plants, since very low wattages are available"
FS-Deluxe
"Perfection in quality and performance
The GIB Lighting Flower Spectre Deluxe does not shine merely due to its excellent workmanship. Here it is above all the internal values which count. It is ready for operation in any position and provides first class lumen efficiency: FS Deluxe 400 W: 55.000 lumen, FS Deluxe 600 W: 90.000 lumen. Chiefly in photosynthetic usability which represents the measuring value for the usability of light within the photosynthetic process its lamp chromaticity achieves excellent results. FS Deluxe 400 W: 120.000 phyto-lumen, FS Deluxe 600 W: 193.500 phyto-lumen."
FS-Xtream
"For all those who want more
A high end product which certainly will hardly be surpassed over the next few years. The GIB Lighting Flower Spectre XTreme Output Series. XTreme Output means record results in lumen discharge and photosynthetic usability. Of course the measuring values exceed all other results since the Flower Spectre XTreme Output is currently our best product. FS XTreme Output 400 W: 128.000 phyto lumen, FS XTreme Output 600 W: 200.000 phyto lumen."
De aici va faceti singuri parerea. Nu stiu daca estimeaza sau masoara. Dar faptul ca nu zice si la modelul ieftin nu-mi place...

simplul fapt ca numerele sunt rotunde ma fac sa inclin catre estimare fata de masurare. si, cum am spus si mai inainte, e foarte probabil sa fie o manevra de marketing, pentru ca cine nu vrea sa cheltuie mult sa nu simta ca a cumparat un produs inferior, iar cine are bani care nu vor sa-i mai stea in buzunar, sa simta ca a platit aceea diferenta pe ceva "palpabil".

Am o comanda la o lupa 60x dar nu cred ca ajunge in timp util din china. Intre timp mi-am cumparat o lupa 10x dintr-un magazin local insa nu pot zice ca vad tricomii prea bine.
Cu ochiul liber (sau 10x) cum imi pot da seama ca e timpul recoltei?
