Making a Perfekt LED for Vegitativ Grow (wavelangth)

[larstwayda]

i want to buy an Grow LED only for vegetativ grow, and i can choose the wavelangth of every LED , i decided to take these wavelangth´s
400nm
420nm
440nm
460nm
470nm
(they are all inside the blue spectrum)

because i decided to use only lightspectrum, that dont let the Plant produce Flower-Hormones, i need to know from wich color ore wavelangth the plant beginns to floweringprocess?

is the green color (wavelangth) a spectrum that take the plant to flowering? ore not?
can the greenlightspectrum be the reason for blooming/flowering?

from wich Wavelangth ore (nm-Number) we are talking about a flowering color?

this question is realy difficult i guess, because i never saw a LED Light on the Market wich has the color Green


i recordnized that the photosynthese gets worst at around 500nm, but what about the spectrum between 480nm-500nm

????

help me if you can PLZ

you need all color. only blue for veg is a wrong thought.

green is in many LED now today. I think it came from info from nasa showing a green led helped..

flower is done by manipulation of length of night for the plant.. unless were talking autos..


what we know, yes more blue in veg, but that's even starting to change, and more red in flower, which that is not changing.

if we knew the perfect spectrum, we would all be doing it....



anyone at this point is really going to tell you to add whites, even if it's half whites in the panel.

 

[larstwayda]

so, you will take even other colors for your vegitativ grow?not only Blue?
i thourght that the color of light can turn the flower into blooming/flowering Mode?
not only the light-change from 18/12 to 12/12 ?

i thourght that take part for plants that got the disposition to get an Zwitterplant?

i are realy sure that that dont take part? and that the color of light dont make sence for the decision of the plant to get into flowering?

im talking about regular strains (ore maybe feminized once´s) not autoflowering...

thanks for your help, Hope you understand my english, i think its not the best

 

[larstwayda]

when i look at this picture, for me it looks like the plant is changing her metabolism at around 550nm ....

under natural circumstances, the Light of Sun is changing naturly (its not everytime the same colors , from spring to beginning of winter ) because of climatic conditions (weather and clouds).


so you dont think that a STRESSED-PLANT is getting into flowering because of color of light?
i cant believe this...
many people told me the duration of the daylight is not the only point.

because the different colors of light produce different hormones, wich produces different effect on the plants...

maybe im wrong?!?!?

 

[larstwayda]

i mean what about fastflowering plants? some plants they get much faster into blooming than others? that only depence on the phenotyp they are ? ore not? the genetic got different phonotypes , and one of them is flowering faster than the other phenotypes...and these plants decid to go into flowering not only by way shorter daylight....

dont get it twisted with autoflowering plants, they are realy spezial in they treathment

no one I know of has a all blue light. I do believe it was done before though

the color of the light cannot turn a plant to flower, well that we know of yet, maybe if you had a certain color at very high power, maybe.. but as far as we know, no.. all flowering is done by length of night

maybe I don't understand you, but the charts for chlorophyll A and B show uptake in the blue and red, regardless of flowering or vegetative.

yes the suns color changes, which is why we try to do more blue in vegetative ( spring ), and red in flower ( fall ) .. but what can we do, where indoors under artificial light.. were not at a point to try and fully replicate the sun.. that would require light movers, and programmed electronics, many different color spectrum and high knowledge.. until then, we do the best growing using a panel what is available.

well I'm no scientist, what did the other people tell you then, as all I know of and have ever heard of, is manipulation of night length, nothing else I've ever heard of. which is what we manipulate also in nature. more light in summer ( vegetative ) , less light when fall hits and end of summer ( flower ). if you put a plant out in the sun in spring, it will never flower, nor will a plant ever stay vegetative in fall.

take Hawaii for example ( I'm not 100% ) which is why they never have time change, as the light is always at the point where a plant put outside will flower, from what I've heard ( and lived there on Oahu and Maui ,and looking at it now it makes sense ) is the daylight hours are usually the same all year, hence the no time change for Hawaii. which I've heard you can never have a vegetative plant outdoors ( someone correct me if I'm wrong please, always grew indoor there )

I'm sure there is things we can't even begin to understand with plants, and there mechanisms. but no test or anything I've ever seen made a plant vegetate or flower on color. color can have effects on growth ( slow, fast, tall, short... ) and same in flower ( tall, shorter, less weight, more weight.. ) .. which is why we try to understand, what is the best spectrum and when to grow the best plants... we don't know.. it's why we just try a white at it to fill in alot of color.. I more myself think we should mimic the sun as best as possible ( all color ).. my ideas anyways

i mean what about fastflowering plants? some plants they get much faster into blooming than others? that only depence on the phenotyp they are ? ore not? the genetic got different phonotypes , and one of them is flowering faster than the other phenotypes...and these plants decid to go into flowering not only by way shorter daylight....

yes genetic phenotype has alot to do with plants, as each one varies.. like your brothers or sister, you might be similar but different in other areas.. like grow a whole pack of seeds.. one might need more Mg, one might not like as much food, one might need more, one might be picky, one might be happy whatever you give it, one might start autoflowering if rootbound.... all sorts of factors play into what make a good plant good to you..

there were some people trying to do tests with red / far red color to get the plant to flower quicker.. everything I've seen or read has been un-successful to get the plant to flower / finish quicker.

I also think, some people try to flower quicker by using nutrient products.. to that I can't really say, some people say using ( forgot ) will make the plant finish a week quicker... who knows

not twisted with autoflower.. I know much about them as I try to grow them along with my "regular" plants.. and find them comical / unique / interesting / amazing





if you firmly believe, a veg plant only needs blue, then don't let me stop you,

we learn more from mistakes then we do from success, is all I can tell you.

Here is what I use for veg:

3 reds (Cree XPE red P3 bin)
4 deep reds (Luxeon ES EX6 bin or Oslon SSL T3 bin)
2 deep blues (Luxeon ES 450nm M4R bin)
4 warm whites (Cree XTE 3000K R3 bin)

Those are all top bins that are available on stars depending on what country you are in. Check out ideal spectrum led for Oslon SSL 3T bin if you are in europe. The XTE warm white R3 and XPE red P3 are available from Cutter in AUS. The Luxeon ES deep blue M4R is available from steves leds for $3!

I drive them all at 700mA so you end up with 24 watts of dissipation. That ratio gives you 25% actual blue output. It may not be the perfect ratio (who knows) but it sure does work well and controls stretch. I don't recommend using any other wavelengths of blue because 440-450nm blues are so much more efficient than any other, especially when it come to the Luxeon ES deep blue, which outclasses them all and is very cheap. In other words, even if there is a better spectrum to be using, I don't recommend it because this one is so much more electrically efficient (~42% at 700mA).



Good luck!

there are all blue lights on the market

heh wish hps had these efficiencies

i can tell you guess ive even read some biological studies in german language , and they say the blue color of light is the perfekt light for "only vegitative grow" , because its create a more bushy plant
i even find many manufacter led lights that are beeing sold with the spezial adivice that these lights with allblue spektrum are more effectiv than one with more red, and some are sold as motherplant led lights....

i decided to make a light with allblue (different spektrums) with the colors i told

when it dont work, and i realy made an mistke with that, i will just add add another light with some more red....
so it will be no problem...i hope


here is an lamp from a manufactor....for example

^ well go for it man.

I'm not sure if you mean you already have, or are doing it right now, but please let us know. I would be interested.. but I will never build one even if.. working under that color must be very unpleasant.

thanks for the link, I wonder if anyone using a all blue will come forward to let us know experiences.
