You are right that they may not be that cheap, since hitting the right wavelength is the issue with standard LEDs/plus lumens.

I take it this is the product Procyon 100 [Procyon 100] - $600.00 : Buy LED Grow Lights, Procyon 100

It seems to use smt leds it seems.
56 CREE* Xlamp high power LEDs (40 635nm, 16 470nm)

I'll try to resource this a bit more.

Cree reports lab development of 86-lumen LEDs - compoundsemiconductor.net
Two years old news report.
"indicates that the LED industry is at least two years closer than previously predicted to achieving the "holy grail" of 150 lumens per watt." If that's true that's pretty much as good as HPS of course wavelengths will become an important factor, but hopefully its not too far into the future.

If you guys dont want me spamming LED info just let me know.

LEDs generally have a more focused beam than regular lights. I would think that would allow you to have them farther from the plants. That could be good because then you could fit more of them, a lot more of them. Im envisioning a small circular room where the walls emit light from every point.

Actually, you want them close to the plants, since the amount of light greatly decreases as you move them back, even more than other lights. As far as a more focused beam, you can find LED's in 15 to 180 degree beams. Maybe even more by now I don't know. Some are more focused, some aren't. You are going to need to encase a plant in LED arrays to get any kind of decent yield. I'm thinking close and wide beams, not far and narrow beams.

hes right. if the lights are 2X further away, 1/4 the light reaches/hits the plant (Inverse square law)

on the tomato experiment with the procyon on greenpinelane, sfortier kept his around 24 in from the tops, im at about 20, dont seem to be stretching bad....will have new pics up sun...gonna do pics once a week till i have enough posts on here...lol..i can take pics if anyone wants something specific....pic of the LED array or whatever...thanks for stopping in guys...

Paving the way for new indoor grows all around the world! Good luck stealth ill be watching close

Opie Yutts · #32 (**permalink**) Jan-27-2008, 21:02

Me too. I hope you do good. I would love to switch to an all LED grow.

SnSstealth · #33 (**permalink**) Jan-27-2008, 21:44

alright guys....these pics are one week old sprouts. lookin good so far, had a few stretching a little bit, but just moved some pots around and they are fine.....

yay....looks like i have graduated to not using photobucket.....lol...babies lookin good so far, had lil stretch scare on a few, but just moved plats around and they are fine.last night i started adding fox farm big bloom.

DoDoFoShoDoe · #35 (**permalink**) Jan-27-2008, 22:21

Excuse me if this has been answered, but where exactly are these plants being grown? in a custom made box? do these LEDs cover up to a 10 x 10 area each?

50ul }{4ck3r · #36 (**permalink**) Jan-28-2008, 01:13

well any pic without the led's on...crappy pix...

SnSstealth · #37 (**permalink**) Jan-28-2008, 02:37

the plants are in a 2x8x10 closet. lined it in mylar. yea, HGL says each light covers 10x10, but we are using 3 of them. and sorry about the pics, but im trying to preserve the integrity of a pure LED grow. dont want them to touch white light. ill try differant light settings on the camera. its a 8.1megapixel cybershot. any ideas on getting a better pic let me know. And to weedhound, cmasfca, opie and rock, my bad about the forum ettiquite, ill get it down. thanks for the interest in the grow guys, ill keep updates current. if anyone wants to know red/blue ratios, or Nm, layouts, whatever, ill let ya know. $600 is hella lot for a light, so hopefully i can answer any questions before someone wants to get one.

I'm guessing you'll be able to at least see whats in the pics once the plants get bigger. Those babies are still, well, babies and are tiny. Hope to see this entire log, all the way to the END. Keep us posted !!!!

sublime27 · #39 (**permalink**) Jan-28-2008, 07:26

looks good stealth, ill be watching as i too am very interested in the led growing lights. Do they each have their own reflector?

no worries dude, 'learning curve', i'll give ya a pass

and I'll shuffle ur Q over here, and answer it.

whiskeytango

how would i mount the fencing? lke a table maybe with four legs?

when to train? basically, when tall enough. prolly 4-8 nodes, depending on growth.
should u top? thats a personal call, it will theoretically add 2 weeks to ur cycle, 1 week repair, i week recovery to point u were at b4 the cut. thats not nesesarily a bad thing, just a thing to consider.
also, its a question of strain, grow characteristics, and ur space.
i would say if ur gonna go LST or Scrog, u would want to top once or twice, but, im no expert. Topping will help them stay lower and bushier.

I've reviewed ur setup and log and am confused.
These r babies dude, why r u using bloom nutes?
again, i'm no expert, BUT u need veg nutes first.
I'm not familiar with this strain, and certainly no idea how these funky lites will effect your grow, but, i would think u need about 5-7 weeks dedicated to the veg cycle b4 u start pushing them to bloom.

and to be candid, these pix suck man,,,,welll,,,,unless i was trippin.
dont be so crazy bout "no white lite".
get us some decent pics so we can see whats goin on.
There was better lighting in the pix from the Mars lander

a 2 minute change in lighting (especially this early in veg stage) is no big deal, really

as to how to assemble the scrog, I am a total novice and only experimenting myself.
if u have the area to install it semi permanent, i would do it something like Opie or MVP are doing it.
but, here's another consideration to keep in mind.
these LEDs ur pimpin are a serious wild-card in my book. u may be one of the first to try it. i havent seen em. (personally, considering cost, i woulda 'passed' and spent that kinda coin on something proven, but thats just me)
Now, considering the LEDs r an unknown factor, I would do a couple la-naturale, and a couple LST. Why LST? IMHO thats a bit easier to manage and shuffle the pots in ur type of a setup. Again, thats just my opinion, i got a belly button too

either way, those babies need WEEKS of growth b4 u think about doin anything like manipulating their growth.

ok, that should give ya somethin to gnaw on for a while

btw- i aint hatin on ya n ur lites. sometimes its just easier to say it straight, rather than sugar-coating my thoughts.

long as u aint wearin a man-skirt, we should be cool

keep goin n keep us updated.

I've never seen a pink grow before.....

Keep us updated Stealth, I'm interested in this

You might be able to set the whitebalance in your cam. You have to use a white sheet of paper (or better slightly grey, but white will do) and take a reference picture for the camera of it under the pink light. The camera alters the colors accordingly, but the plants would still look dark, since there is no green in the spectrum
