well honestly I've been thinking about what the "perfect" spectrum should be. and i have a couple of ideas. first, by best do we mean efficiency? or actual absorption? on the high times chart there shows to be pretty much 100% absorption at 425nm and 660nm. thinking about this i started thinking...if we provide only 425 and 660 then most of our light we supply in those two wavelengths, and if the charts are correct, will be absorbed almost 100% , meaning almost almost all of all the light energy we put out will be absorbed by the plants, making the LEDs about 100% PAR (right?). isnt that what we want??? do we really need to hit these other peaks (440,470,642,etc.) or can we just supply these two wavelengths, 425 and 660nm? having more LEDs and colors will reduce efficiency but also increase absorption by the individual pigments. as of now i don't think i could answer these questions. but with some testing i think i can. i will perform a test with 425 and 660 on one or two plants and on another ill try all the peaks, and form there we can compare the results, and hopefully that will tell us if supplying just 425nm and 660nm is just as good (and even more efficient) than providing all the peak wavelengths. as of now 425nm high-power LEDs are not commercially available, so this is one limiting factor. also 660nm high-power LEDs are a new development and still have some improvement. also blue light has more energy than red light, so providing more blue light in the array would mean more PAR or umol/s/m^2. but we still want to keep the light ratio of red to blue right at about 2:1 B:R for veg and 7:2 R:B (something like this) for flowering. I'm starting to think about this whole "peak" wavelength we've been talking about for a while. do the peaks even matter? at 470nm there is about 81% absorption for all pigments and about 77% for chlorophyll b. im just tossing ideas around here.

oh fuck wrong thread...sorry SnS!!!

Wow you can't be more of an asshole Stelath YOUR GETTING ON MY NERVES? I'm done with you your blocked.

Your Friends are cool. They sent me REPS for my post on led's Asking me more info buddy.

This whole LED started out with NASA and the space program NOT YOU.

Hey They don't test anything NASA in there advancments? There just a bunch of assholes like you stealth. You know I did do a little resarch on LED and was told they can mesure the light and draw it in diffrent ways. Even thought about possibly designing one. Maybe Ill just back PHYS. Was going to take a trip to Cali to sit with there engineers to see if it's feesable. To run test to reach maximum output.

Ok grow up I'm done with you your blocked.... You can bring a JackAss to water but if he does not drink he is still a JackAss.. LOL anyone want procyons just order and wait 3 days.. BLOCKED

Green leaf you should get your own thread and do this type of thing. Regardless of what you think Stealth has done a LOT of work here......this thread alone is 33 pages and represents their work. You should show some respect just generally but that kind of crap will get you banned anway before long.

SnSstealth · #**804** (**permalink**) Mar-30-2008, 12:42

i thought you were done with me and blocking me? hate me i don't care,people are repping you, great, your rep is disabled though... just quit flaming my thread. dont post in here anymore if you feel that way...easy actually, i would think. if you wanna talk about relative shit in the thread fine, AGAIN i say, we will all gladly talk about light theories, in the light theory thread.

WH Thanks for the heads up my man. He just kept attacking weather LED T5 any post "SPAM"?. We are all modern day bootlegers and I agree there should be a certain level of RESPECT. I have not felt that here look back @ all his Quarrels. Well I'm done he is blocked. It's over

Hey Stealth what day are you guys on now? I mean total from germ. I see that you posted on Jan 21 that they sprouted but want to ask just to make sure. thanks

SnSstealth · #**807** (**permalink**) Mar-30-2008, 13:48

thanks for stoppin in apoc....jan 21 was the sprout date... and today is day 33 flowering.

Cool thanks sould be getting my Procyon in the mail this week then will start my germ. As I remeber you started your Led's high and then moved them down. Would you start lower at the begining of you next grow or stay high then go low again. Was 20 at the begining then 14? Been reading so much on these boards since I got here things are melting together a bit.

ViperC6 · #**809** (**permalink**) Mar-30-2008, 14:46

But yea some real

love for you. This is something I have been wanting to find out about for while and I just felt I had to leave a comment for you. This makes me

every time I see pictures of your buds it makes me believe I could use mainly LED's to get huge flowers. I plan on making a grow that is about closet size using a bunch of led strips and a 1000w HPS w/ Cool Tube.

SnSstealth · #**810** (**permalink**) Mar-30-2008, 15:46

good to hear apoc

...the guys are quick about sending them out too..i would start them at 16 in. that seems to be the happy spot for the procyons. from what we have seen

good to hear viper, the first link in our signature will give you some great info on building LED arrays, part numbers everything. good luck!

wuz..up ,, hey I wanna goto the droolzone..heh..heh..cam workin.. snap..snap....heh...heh...heh......

cheapguy · #**812** (**permalink**) Mar-30-2008, 22:27

I'm watching you sns i didn't read all the post because i'm lazy
I'm on my first grow and am very interested in LED grows i can't wait to see your final product keep up the good work,your plants look better than mine,we are about the same time into flowering
keep us posted
Later Bro

SnSstealth · #**813** (**permalink**) Mar-30-2008, 22:54

thanks for stoppin in cheapguy!
pics on tues veggii...unless i get spunky tomorrow and come home from the beach early...hmmm...maybe

veggii · #**814** (**permalink**) Mar-30-2008, 23:04

wholly crap I guess I missed the pissing contest!!
Wt,,DB .. no worries their all just jealous of ya'll

and hurry up and get spunky!!! take em in da mornin for ya go ..

plz..plz...plz...plz...

Hey SNS, maybe you should start a flaming thread

But seriously, lets try to keep this civil. I don't mind scrolling through all the compliments and even some of the off-topic stuff, but i hate seeing all the flaming. I guess i try to make it a policy not to say anything on the web that i wouldn't say to someone face to face, but that's just me...

And regardless of the wave lengths and spectrums and peak whatever, isn't the purpose of this thread to see whether LEDs are a legitimate alternative to HID?

Everyone smoke a joint. You'll feel better, i promise

How many lumens does the Procyon release?

SnSstealth · #**817** (**permalink**) Mar-31-2008, 00:43

sounds great to me gandolf.

dont worry im sure most of it will be erased in the morning when the mods check in.

the real purpose of this thread is to see if a light, being sold on the market as a "grow light", can do what it claims without supp. lights. and weve stated we will supp. w/ LEDs if/when the time comes. I apologize for being short with some, but weve had two months of people telling us were wrong, that we must do this or that or we will fail. we dont want a fight from anyone, truly we dont. this is meant to bring people together so we can see what will happen if you spend your money on a pre-made product.

I'll get a update post together shortly. by the beginning to mid-may we will have full harvest numbers and be able to make a consice, couple of post, thread attached to this one showing the progression and results...if were able to type at that point...lol

lit it up and passin it over

3000-10000 depending on distance. however lumens are not a good way to determine plant growth abilities of LED lighting. lm's are rated by the eyes perception of light, which is basically opposite of a plants absorption spectrum.

thanks for the interest
