ey man, not the way to go
many people dont use LEDS
cause the light just conserves energy
but isnt that hot.
my friends have told me that in
the long run it wont support the bud
when it grows and it will just fall....

LED's are the cool new(old) thing but they arent really good enough for mj yet. Maybe if you want to be different you could try lasers. Dont think anyone tried those yet. lol. j/k. WM

Hey taz I know the advertisements say that LEDs are the best grow lights, but they don't cut it when it comes to growing sensi. It usually causes a lot of stretching and doesn't have enough lumen output to supply good bud production. I know this because I used LEDs on my first hydro attempt and was saddened at how long the grow takes and how small the yield is. I know you want to be different, but it is best to learn the basics before you reinvent the wheel.

Use a mixed spectrum hps+ MH at the same time, that would make you different no? From EVERYTHING I have seen of actual MJ grows using led's i would say that if you continue to use them alone you will differently be different from your friends that use HPS, They will be high.
Seems like most of the led grow's i have seen, no matter how they started were supplemented with cfl's because the grower was just fed up with how slow things were moving and the tiny buds they were seeing.
Sell those bitches on ebay, or save em to veg if your in love with the things.
Good Luck

So what about the theory of ADDING led's to a grow? I plan on doing a nice DWC grow on fox farm nutes, with T-5's (Due to space / heat constraints) and i've thought about doing LED's thrown in. Ether in the walls, or along side the lights. Since im going SoG, it'll be easy doing all red lights. Is this worth trying, especially since it will be my first full grow (have plants given to me growing now) and i'd rather not do it if it doesnt stand a chance...

hey i have a question my brother just ordered a led panel yesterday for a little grow closet setup will 1 per plant be sufficient im completely retarded when it comes to science and light so i got me a hps lol! the panels are roughly 1 1/4 square foot

Hey worst case scenario you get small buds out of the deal---Keep up the good work-you don't know unless you try.
Note: Have you looked into the high output cree xlamp led's?

It will help, they are indeed good as supplemental lighting (that is what I use mine for now). Mostly any light that you give your plants will help them grow. And remember this, the more light you have the bigger your yield will be.

my last led grow was with soil out of three plants had one female a male a hermi took the female and toped it and got 13 clones out of it rasied them to be 10 inches high till harvest and got just under a oz first time i ever cloned and this was all done under leds this will be my secound harvest this year in two weeks im going fo 12/12to harvest in july ive already started cloneing they were fluff buds but was good weed got 8 seeds from last batch so that what im growing right know keep pollon from last male going to polon a few bud sites on this batch im not going to be defeated if it takes more leds ill buy more 1 put sticks beside my plants to see if they stop growing and there not i get about 1 in every four day and i put as much nitrogen in my solution as i can and run co2 all the time they will bud

"But in order to use plants, you must have an energy source, and that energy source is light," he added. "And the lights we use in our homes are not energy efficient enough to get the job done. So that's why we're developing these innovative technology lights."
Take the common incandescent bulb invented by Thomas Edison more than a century ago, or the type of fluorescent lamps first developed in the 1920s.
Both contain electrodes that burn out, so the lights must be periodically replaced. And both gobble up electrical power -- a precious commodity in space -- while generating heat, which must be dispelled from closed environments such as spaceships and space stations.
"Standard light sources that we use in homes and in greenhouses and in growth chambers for controlled agriculture here on Earth are not efficient enough for space travel. Not only that, they don't last a very long time," Goins said.
"And in space, heat is like trash. You make it, and you've got to get rid of it, so we don't want heat. We want light."
In recent years, dramatic improvements in lighting technology have provided NASA and its support contractors with new means to develop low-power space-farming systems that will last the life of a building -- or a greenhouse on the surface of Mars.
Working in plant growth chambers the size of walk-in refrigerators, Goins and other plant physiologists here are experimenting with blue and red Light Emitting Diodes, or LEDs, to grow salad plants such as lettuce and radishes.
Similar to devices now used to manufacture advanced traffic lights, the LEDs enable researchers to eliminate other wavelengths found within normal white light, thus reducing the amount of energy required to power the plant growth lamps.
The LEDs generate less heat, and while leaves take on a black hue due to the lack of green light to reflect, the plants grow normally and taste the same as those raised in white light.
"What we've found basically is that we are able to limit the amount of color we give to the plants and still have them grow as well as with white light," Goins said.
"Being plant physiologists, we know the chlorophyll molecule well enough that we know which wavelengths most efficiently stimulate plant growth, and it turns out to be blue and red. So I don't have to devote energy to green light, and my plant will grow just as well."
Nevertheless, green light can be added for aesthetic purposes.
"So if you're in orbit for a long time, not only do the plants taste good but they actually appear as plants do on the ground," Goins said. "But we also know we can eliminate the green light if energy costs are a concern -- and they usually are in space travel."
Another bonus: The LEDs can last the length of a round-trip mission to Mars, unlike incandescent or fluorescent bulbs, which require frequent replacement.
A second long-lasting light source being tested here: Sulfur Microwave Lamps.
Now used to light up large airplane hangars, shopping malls and gymnasiums, these high-performance lamps were first developed in 1991 and one day might be used to light conservatories on the surface of Mars. "The microwave lamp is a technology where we're thinking about a large-scale system like a greenhouse on Mars, where we can illuminate a large growth area," Goins said. "It is the most efficient electric lighting source known to man."
Twice as efficient as other high-intensity sources, the microwave lamps can generate as much light as the noonday sun. The light in fact is so bright that it can be funneled through pipes and then distributed over large areas, such as a hothouse on the Martian highlands.
The lamps also are dimmable, so space colonists would be able to attenuate light within their greenhouse to match the growing cycles of their crops.
"When there are small seedlings, you don't want a very bright light," Goins said. "But then you could turn the lamps up accordingly as the plants got bigger."
The bulbs, meanwhile, are simple hollow quartz spheres with sulfur and argon gasses that are energized with microwaves. And with no filament to burn out, researchers think the lamps could prove to be the perfect light source for a space colony.
"Theoretically, the microwave lamps should last for years and years, and we've found that to be the case," Goins said.
With an investment of just $80,000 to $100,000 over the past three years, the high-tech lighting systems here have been used to grow potatoes, sweet potatoes, lettuce, spinach, radishes, wheat onion and a whole plethora of herbs such as marjoram and parsley.
The plants typically are grown hydroponically, or without soil. Water laced with a nutrient solution is circulated within plant growth chambers that are lit up with either the LEDs or the Sulfur Microwave Lamps.
And while greenhouses and space colonies on Mars are still a long way off, Goins said a specially designed LED plant growth chamber should be ready for launch to the international station within the next three years.
"I would probably call it a salad machine," Goins said.
About half the size of a tall file cabinet, the plant growth chamber would enable station astronauts and cosmonauts to grow and harvest salad greens, herbs and vegetables during typical four-month tours on the outpost.
"Now this salad machine wouldn't be built on a scale large enough to actually give the crew all the food they need," Goins said. "It would be just a supplemental endeavor in the near term."
But it would have psychological benefits for station crews, too.
"When you're inside a can for several months, I can see where having something green and living onboard would be very appealing," Goins said.
"So to have an herb garden or a salad machine actually on the space station would make the stays in space more pleasurable," he added. They would just love that."

taz you just don't get it. The reason you only got a little less than an oz on your last grow was because of the LEDs. If you would actually take some of our advice and get maybe a 250w or even a 400w mh or hps you would notice HUGE gains in your yeild. With several plants you could easily make it to 3-4oz in total with just a few plants. Or you can stick with your LEDs and make pitiful yeilds with not much potency.

have you ever seen a hps exploded i have and when that went the baluster fried and flames came out of it i do electric work for people and ive seen a melted ballester nothing agaist them but not me im going to prove you all wrong i only got a once because i did not let my clones mature enough the min they rooted i put them right in two flowering at 3 in by the time they were ready to harvest they where only 10 in im not doing this for yield im experimenting and having fun and for the qaulity of the last harvest it was good i smoked it with friends that dont know that i grow and liked it if something new came out i wood try it because its a hobby i have plenty of it hanging around to not grow i love to grow for the fun of it not to be like every body else
