50W Killer Setup GOD knows how many LUMENS!

(i mean upper one).
The luxeon people sell LEDs with exactly the same wavelength output, and some cool and warm white ones with broad outputs due to phosphor coatings. They already sell everything you need
While I'll say that LEDs, if you get the 3 watt ones and rig up at least 100 watts for a 2.5 square foot space, will work nicely. If you use short autoflowering varieties, they will work excellent.
That said, the results he got with what you saw are actually below what an experienced grower would get with the same equipment. Too much was due to that Fluorescent lamp added in.

^^ rofl looks amazing how that gras grew ! you could use this to make a fairway look really nice on the folf courses
hahahaaa

you've played folf too....sh*t me too...I didn't think there was anyone else out there that had played folf before!....j/k....just got a REALLY weird sense of humour I guess

if your growing 2 plants i don't think there gonna come a knockin at your door...there looking for people that grow like 100+ plants.

With just 2/3 plants probably probation.............but we dont even need to think about that!!!Thanks for the advice! Can somebody confirm that how much I can get if the swat smash my door?? Im living in the US!
Thanks

i think alot of you have missed he boat on this one..to me it seems LED make an ideal platform for the likes of LR#2 etc.. i think the short strains should do well under this kinda setup, as they seem to penetrate the top 12" of the canopy quite well... so on a 12-18" LR they should provide adequate lighting throughout.. no?
either way nice experiment.

I have done a small amount of research on LEDs aswell as reading on these forums. It seems people are bad mouthing LEDs with out even trying them. These posts or journals are being hit hard with such remarks. One of the common ones is watts comparison (LEDS to HPS). Watts is power consumption not necessarily light emmited that the plant uses. HPS has worked and is proven to work at high temperatures and power consumption. While LED's are emmiting the main spectrum that the plants use to Veg and flower with minimal heat and power consumption. To me this is a comparison of that similar to cars. Large SUVs hog gas while a small honda gets better gasmilage both are just as effective for A to B travel. Might be a shitty example but it gives you a general idea. Just keep in mind you may have to adjust methods for these lights over the old method of HPS and the like. The other is lumens. From my general understanding lumens is light visible by the eye. Not light that is necassarily used by the plant. I see it as an illogical basis to say LEDs are inferior. That said, I would like to see other more experienced growers do similar experiements to see if this is actually just as effective as other lighting methods. I don't mean to bad mouth the person that did this test, but he lacked experience which is understandable for a first time grow. I am not saying LEDs are the next light everyone should buy for their grow operation, just that they are worth the chance. But then again 'Why fix it, if it ain't broken.'

LED's are the future, unfortunately we are in the present.
The plant doesn't see lumens it absorbs them... as much as you can get except for far the extreme ends of the spectrum, and green. Intensity is very important in getting a decent yield.
I agree that led's will take over fluoro's soon if fluoro's do not make the intensity jump... but they have a long way to go before they can compete with HID.
If you want finished plants that don't have a full cola, grow fluoro. If you want even less than that, use LED's. The light simply doesn't penetrate far enough, doesn't have the luminosity. Until they do, i will stick to HID's.

No, LEDs are clearly now, and emerging. If you look at the led lamps like the ones used in this thread, then yes, they aren't so useful, other than supplemental lighting in or near a window. You can buy 3 watt LEDs that truly make these lamps the grow room equivalent of the E Z Bake Oven.
I walk by a few buildings illuminated by LEDs everyday. They have STREETLIGHTS in their parking lots which are LED. They definitely penetrate.
efurmother was exactly on the nose about lumens... that's why a green lamp (even LED) throws out more lumens than a far-blue one. Lumens are a measurment based on human vision. You could have a lamp, or a few lamps with half the lumens of an HPS, and get a far superior grow, as long as the wavelengths of light were proper. So much energy of an HPS is wasted on green light, far red, and IR (heat) that when compared to the efficiency of LEDs (even now).
Lumens... great for reading, or watching food cook, not so for plants growing. Of course if they are applied to a number not as subjective like 2700K or 6500K, they can be a little useful.

I have to bad mouth the leds...I have 5 led lights on my itty bitty grow. 2 red par 36 (I think) and 2 blue, and 1 white. They actually seem to respond better to the white one...anyways, I bought them from ebay and after the research I did I was lead to believe that these were the high-output good ones. After 3 months or so the plants are a little over a foot tall and don't seem to be going anywhere...even though they have been flowering since 9 inches and for two months. I could go on into details on temp, humidity, etc but this is about the lights.
In my humble opinion in this horribly worded and grammatically incorrect rant...the L.E.D. lights are good for veg, but not for flower, unless you have a shitload of them. More light is better! And these just don't pack the punch needed. At least not what I was lead to believe. Hope that helps!

you have no idea as to what you're talking about. ive had a long day and i really dont feel like reading about some kid claiming a few LED lamps with half the lumens of an HPS would result in a far superior grow. if LEDs are so "now", then go buy one of those ripoff UFO lights for $600, see how equivilant they are to a 400watt and enjoy spending $600 for something you could have paid $120 for and gotten the exact same results (400watt off htgsupply = $120).
It's true! YOU have no idea of what you're talking about. You haven't a clue, while I do!
I mean those cool 3 Watt plus LEDs that are called Luxeon IIIs. The ones they use as automobile headlights
I would never even advocate those stupid lights filled with the little ten cent LEDs, I mean LEDs that are used for real illumination, not indicators.
But enough of that, I don't have the time to educate the unteachable.
The pic below is of a 35 LED array, made up of 35 3 Watt LEDs. It covers an area of about 30"x24". It produces at least 35 grams of trimmed, dried flowers per week, or 1 lb after 10 weeks (24 plants). I only grow Masterlow autoflowering under it. All in total it cost $160 to make. Unfortunately, it will only last 5 years at 24 hours per day. The success is due to the light being evenly spread out though the little grow space. It is made of royal blue, blue, red-orange, red, and white LEDs. It's not too hot, so odor is kept low. It CLEARLY outdoes an HPS, and MH for my needs.
Lumens???.... you just don't get it. U CHaMP! Thanks for your input, chronicless.

show us proof. show us your whole setup. show us its worth 3 months of time working with these tiny lights for an amount of product that is 1/8th what you would get with real hps.
