Guys,

Just blow this off if it has no bearing but two things came to mind from this novice's collected fragments of info on grow lighting.

1. Is that often mentioned rule of thumb applicable to other bulb types where isn't overall wattage supposed to be a significant measure of growing capability?

2. Other thing was the prism effect in nature... suggesting here that in considering a selection of wave lengths you - being more familiar with basic fundamentals than me - could prob refine estimated wave lengths on the basis of calculating differences in angles - seasonal changes - and then finding the true or existing data on the refraction and prismatic effects of the atmosphere - and somehow come by better figures for the wavelengths that way.

Sorry if totally inapplicable tho.

turtle420, did you get the impression that we would be stuck with the round format? Would there be any advantages to rectangular arrays?

Nice find tho, really interesting, given the reduced heat advantages.
All the exhaust/blower $$$ could go back into the lighting but I'd definitely downplay that aspect in discussions with the R&D dudes.

Out.

Yeah according too the led light study you would need about 216 (around there) watts of led lighting to equal 1 1000w hps light.

someone in the uk is selling the rectangular red led's cheaply just search under led lights at ebay and you'll get about 31,000 hits. from everything I have seen so far you would need to buy many many led bulbs to equal 200 watts

Rezinator,

I think that the rule of thumb of watts for growing capability, does apply.

As to the different wavelengths just as in nature... the idea kicks-ass. It would be very cool to have an LED array that, instead of turning ON/OFF, could start shutting off individual LEDs in the time-frame of, say, 30 minutes. So, during those 30 minutes, the plants will get a quasi-sunset effect, with different colors of light and everything. Interesting...

As to the round/rectangular array... yes, that's one of the advantages that we can have... we can basically build any kind of shape with these LEDs. I would preffer round for simplicity... BUT, ideally? I would have rectangular shaped panels of LEDs. You could hang those on top of the plants and on the sides... I mean, one of these panels will probably be about 1, maybe 2 inches thick. So they will be pretty versatile regarding mounting options.

I can envision a grow cabinet with all the walls and the "roof" covered in LED panels... wow... those plants must really get some wavelengths!

Over and out... keep us updated everyone!

PS: Sorry if this post is kind of incoherent... I'm still half-asleep.

what are you trying to do? save money on electricty?

grow your own marijuana, the regular way and give up on your led dream

Thanks for your input seattle.

Hey Turtle... just get a couple lights and try it.. shit... you don't need to grow MJ... just get one of those bulbs and put it in a desk lamp and try some tomatoes.. or even better yet get a tomato clone...
worth doing just to say .. you did it!!! noty the stealing part,, the led part

love is you

i feel that the theoretical phase has to end somehow. just one guy saying "i'm growing mj s now, and leds are working well.", will be a great enthusiasm for all of us.

my place is not proper for growing anymore. but i think i'll find a place to use these leds as fast as i can.

With lights I have found that from 400, to 600 there is a different in the plant and thc and from 600 to 1000 the samene plant... and at this point I'm working with some LED on 12 VDC at what would be about 1750 to 1800 watts. with some UV light in the mix and so far they are doing supper good. the grand kids broke my cam os i'm sol and can't send pic. after I buy the LED's every thing is on 12 VDC fans pumps all... and I found the cooler you keep the led's they last longer... this is the first grow this way. there on 24/0 then 12/12 in 3rd week so far. from seeds about 6 1/2'' to 7'' tall. fat coles.. just make shur you get the right things in the LED's,,, SOME are FU*KED for what you are doing.

there are a few threads about people growing with led's on overgrow.com (use the search engine there)

LiteSpeed,

When you get a cam, can you post pics ASAP? Please... These LEDs that your using... did you fabricate them your self?

You say you have about 1800 watts... of LEDs?! How big is the setup?
And about those fans and pumps... ??? Have you found that the LEDs have to be cooled? As to they last longer::: about what the average lifespan of your LEDs?

What wavelengths (nm) are you using?

Can we get some pictures? Pretty please...

puter fans on the base of the led 20c. low 60's or lower. they will last from 5 to 7 years, all fish tank stuff reworked to 12 VDC heaters pumps, timers, car heater fan for plant. friend is a (EE) did most of the work for me there 6 lights 8 inch each and cover the plant. 4 sides and 2 on top this is only a trial to see what they will do if it works or not. need a battery-charge and battery. Lights 400 to 500nm and 575 to 700nm and the UV's I don't remember what they are. the set is 4' X 4' X 8' hight.
sorry about the pictures the grandkids broke the cam. and I 'm on fix income. where i'm at one plant will get you $2,500 first time and 1 year jail. They let the meth cookers go free. we have 30 DEA in town looking for the green, man they have got 6 18 whellers full so far in a town of 350 people. and they said they can not burn it here for it will put the people in the hospital they say it is worst then PCP. if they burn it. all B S...

Fuck damn litespeed... that town of yours seems fucked up by the DEA. Hope they leave soon. Stay safe.

But on another note; you're a town that so far, the DEA has hauled out six 18-wheelers full of weed... you bunch of stoners! LoL!!!

Hey man, sounds very intereseting your setup. Please keep us up to date when possible

Is this your first LED grow?
Is this your first cannabis grow? (just asking)
Have you noticed major differences in???::: growing speed? flowering?

Question (yet another one): Do you 'divide' your bulbs and turn them on at different times? Or do your turn on the entire LED setup at once? . . . I mean, do you have special LEDs for flowering, and others for vegetative? Or do you follow the entire grow cycle with the full set of LEDs?

Sorry for such many questions... Thanks for the possible answers!

Looking forward to your comments,

-turtle420


Here are two threads I'm following over @ Overgrow.com:
http://www.overgrow.com/edge/showthr...?pagenumber=29
http://www.overgrow.com/edge/showthr...5?pagenumber=5

I have been growin since the 60.
This is the first with LED. at a little over 3 weeks.
so far it looks like they are growing a little faster then with HID & HPS. all I can do is wate & C
have not got to the sex or flowering yet. this is from seeds.
The LED's Lights 400 to 500nm and 575 to 700nm and the UV's spectrum one light for every thing.
as the plant grows I will turn on more light. there are only 4 on it now. out of 6. we set the lights up like the (Sun) out side. duplicatethe Sun... the double EE say's I'm not the sharpest knife and i tell him he has No common sense. and we get long fine. electronic is not my thing, so have to leave that to some one that knows it. The threads your following over @ Overgrow.com: and what you post here he said look good. and we are talking about doing the 2 light way also. 1 for grow and 1 for flowering. He thinks that the all in one is the better way to go there 2 that has more red and 2 that have more blue all I can do is see what they do...
as for stoners, this part of tn puts out all most as much as cal. in green. last year they say this part sold about 2.5 B thats after the dea/th come here.

Seems like a more expensive route than HID's.

Definitely my good friend.

I think we're still about 4 or 5 years off using LEDs for grows. I've seen insane setups in Overgrow.com of about 5,000 LEDs... ALL soldered by HAND?!!!!

Sorry, but I preffer to cough up some $$$ than to make 10,000 soldering points. But, tCreator, please keep us updated with the LED thoughts that cross your mind. I'm still very much interested. Maybe as supplementals.
??? Great to see you posting here!!!

Will do. I'm tired of the lounge lizards.

Man, I just don't understand this expression. Care to shed some light? Thanks

stores lyk CVS, Target, Walmart.. they sell LED lamps.. with like 64 mini bumbs that make this bright ass fuckin lamp, i had a LED flashlight n it had 3.. could we use a couple of those to produce the same/similar effect on the plants??

If we try it on other plants... and they grow.. the mary J should too grow.. right?? so someone go head n get a couple tulip seeds or somethin and try it out!

...

AHA!
