LED lights with pics

[SmknVTEC]

Yes LED's will save on electricity over an hps. However with the spread in price with LED's being so expensive, I think I figured out that the original out of pocket expence initially of the LED's will be saved after two years of use.

LED's can be used for flower. I proved a few pages back that they will flower nicely. I had three plants grown under the LED's for about two months, then switched to flower all in 1 gallon pots and got about 1.5 ounces for 3 plants. So it does work all the way through.

Well, I hope there are no ill effects from using LED light that seems to create a satisfactory plant. One thing that's been bugging me is that the plant doesn't seem to want much food, according to VTEC. I hope that doesn't make for an unhealthy plant that can't grow big buds. I'd like to hear from someone experienced (I've never grown anything) who's happy with the buds after using LEDs in veg phase. Until then, I'm a bit concerned.

I do want to stress I don't really know anything. I'm just trying to supply scientific skepticism to the LED interest.

Hey bud it is very true the plant needs only a fraction of the nutes. My LED plants from page 16, 15, 14 were vegged under LED's for one month and then flowered after that. While the buds did not fill out quite as much as they do with my 400 HPS, the plants remained green and healthy the entire flower period, which I was never able to duplicate under HPS. The high and smoke from the weeds grown purely under LED's was nothing short of excellent. Nobody knows why the plant needs only a fraction of the nutes and why it is so easy to keep plants green under LED's but I can attest to being a seasoned, advanced smoker and that LED grow weed is every bit as potent as weed grown with other acceptable lights.

Uhm. Yes, and Yes. POTENT. I pulled a couple small buds for a half harvest...mmmmmm.

[SmknVTEC]

Ha ha nice work bud, your thread is awesome too.

[wtfk]

Hmm VTEC, so maybe I misunderstood your comments on your experience with LED...I believed you considered your LED buds unacceptable overall (because of the small size.) In that case, I'd be very hopeful that improvements in the spectrum would provide an acceptable product. Perhaps other forms of light are similarly "deficient" in meeting the plant's needs in some parts of the spectrum then.

LEDs are the future.. its only a matter of time. As soon as prices come down as one of you mentioned earlier, Growers will be having an awesome time. If I had the extra cash I would proly get a few good lights for vegging and still use my HPS for flowering BUT flowering with LEDs is possible... its just different.

Oh and response about the less nute uptake and water jazz. I would say thats due to less heat being beat upon them...as far as less nute uptake, possibly due to slightly slower growth? Idk

Check out these two threads if you want to know more about LEDs, LED wavelengths for MJ Procyon LED grow, etc.

http://boards.cannabis.com/indoor-li...row-light.html This one talks about wavelengths, pulsing LEDs, and a bunch of cool stuff that will eventually make LED grows waaaaay efficient and just as effective or better than HID if used properly.

http://boards.cannabis.com/grow-log/...-grow-log.html This one is person growing with 3 Procyon LED lights... interesting indeed. Oh, and with the LEDs he noticed a higher production of resin on the buds. It makes me think about LED Grow + Hash Making

actualy LEDS aren't the future, plasma bulbs are

this is a much better lighting technology compared to LED

Naw man I was actually impressed with the LED plants and potency was identical of that of HID grown plants. Only difference was the yeild which was a bit smaller with the LED lights.

Yeah man could be the reason why less nutes but even CFL's need more nutes then LED plants and the heat is about the same. Thanks for the links I will check them out in detail.

Yes but do they grow plants? We will see.

1 1/2 o outof 3 plants!! i get that out of 1! how many wats of LED are you using? matbe using a 250 hps to supliment would bump up your crop, just watch the heat.

Check out where we got them. http://www.luxeon.com/ my hoods have the Luxeon III.

Yeah but how long did you veg and what size pots? Don't compare apples to oranges.

Yeah I got over an ounce dry from one plant in a three gallon pot grown under a 400 watt hortilux hps. So, the purpose of this LED grow was to prove that LED's ALONE grow weed. Supplementing with other lights known to grow weed doesn't prove anything because how do we prove which grew the plant; the LED's or the HPS? So I did not want to supplement anything as it would ruin the experiment.

BTW I currently have three cloning mothers under the LED's just vegging away. LED's work great for clones and moms that don't quite need the lumens that flowering plants need.

[khronkaiser]

been a while since i visited this thread, i looked at price comparisons and such with LED lighting.

it seems if u want to equal a 1000w HPS with LED's your looking at $2,500...
or $350-$450 for a 1000w HPS. Hmm...

I think SmknVTEC mentioned the lower power draw on the LED's, they draw 1/4 the power and produce the same lumens while enabling you switch up the spectrum.

Anyways, just some random info

[SmknVTEC]

OK so lets say $500 [because I suck in math and 500 is easier to add] for an LED equivalent to a 1000 watt HPS and 1/4 the savings in electricity. With your numbers LED's start saving 5 years after initial purchase. Not great but in time it will get better.

I have been doing a little research in order to grow my own avoiding getting wripped off by college kids and going dry, like i am now! I've just moved country so lost my suppliers after 18 yrs of smoking.

My wife is limiting my spending so i thought LED was the answer, no ballast or cooling fans needed so easily hidden and easy to set up.

Yeah ok i'm getting to the point, i've been looking at LED panels on e-bay but the wattage seems really low, compared to Fluoro.

Blue light wave length: 465
Red light wave length: 650
LED QTY: Red: 72pcs Blue: 40pcs Total =72+40=112pcs
Working Voltage: 240V
Power: 45W

What do you think, i only want a small set up in order to grow my personal use? Should i go for it? Or just by the below Fluoro lights which come with reflector etc no ballast required either.

Any replies would be good, Thanks Ty
