LED grow

Hi everybody. I'm new to RIU, and I'm new to growing with LED, so I'm hoping to get some advice, hints and good ideas from you out there.
I started a LED grow on 9.9.09, and it has been under 24/7 light. Today, I'm going to switch it to 12/12.
This setup is basically to get temperatures, ventilation and lights right, as well as to see if LED is worth-wile, so I just started 4 random seeds in one pot.
So far I got three plants - two girls, one not showing, and they're growing fast!
I'd like to hear from you out there. Any luck with LED. How many lights/watts pr. plant - or pr sq. foot?
Show me your pictures, and tell me how you did it. Maybe we could get a forum on LED grow going. There's so little info out there.
I'd love to see pictures of harvests, if any of you got that.

Thanks for responding. In addition to two females, that I put into flowering today - I planted about 12 seeds, and I saw two had sprouted - so I'll get the camera out. My plan is to do the whole grow under LED. I have three 90watt UFO's - one for veg, two for flower. What I seemed to experience is that I put the lights too close to the plants - like maybe 6 inches from the top, and that seemed to cause lack of chlorophyll ?
Anyway, the leaves a bit further from the light seemed to do better - so now I keep the lights further away - like a foot. Maybe that is still too close - any ideas.
I went with the concept that more is better, thinking that each light could support one two-three-foot plant - or so.

I have mine at 8 inches. they seem to like it.
i am sure i could move it a little further but i haven't seen a problem yet.

keep me posted on how yours react. this is all new to most people
good luck with the seeds sprouting my friend.

LED First day of flowering, as well as day one of the babies in the veg-room. I just counted 6, of about 12 seeds. I only have 3 plants in flowering - and only two are positively female. I chose to start out in moderation, since LED grow is new to me, and I wanted to break into it gently - that way I will not be so disappointed if things don't go exactly as planned.

Generally I have a bit of 'shoot from the hip' attitude about most things, growing included - so I just tossed some seeds in some really gnarly soil, to find out later, it was way to strong, and I got burns. After a few flushes, the leaves started looking better, and I had decent growth. Then - I think I put the lights too close, and it seemed that the leaves got kind of bleak, especially those close to the light. One plant kind of closed it leaves - not as in drooping, but closed the leaves into a V close to the lights. To my inexperienced eye, that looked as if the plant tried to avoid the intense light.
Yes - intense. To all of you, who might think LED is not 'it' - think again. I run three 90 watt UFO lights, and you almost need sunglasses in the grow-room. I use a CFL just to make the light more agreeable to the eye, as well as balance temperature.
The plants seem to love it. In the beginning, I would keep a CFL close to the plant, and the LED further away, to see if the plant would lean toward the CFL, but no.
The light from the LED is much stronger, and clearly what the plants need/want.
As you can see from my pictures, I go for function, and not so much for beauty. It's a closet - well hidden, with access through another closet, and I have the flowering area above, a veg area under it. That way I get the heat from the 24/7 light in the veg room, keeping the flowering room nice and cozy overnight, when everything is off.
I shut the fan off at night, also. I'd like comments on that, as well as on everything else. Ideas, pictures, questions are all welcome.
The only thing I don't need is to be told I need HPS lights. I am perfectly aware of HPS, but my space with it's ventilation and cooling issues, as well as noise - makes LED a possibility for me to grow, where I otherwise couldn't.

I'm less than $500 into it - everything included. 3 UFOs, fan and couple cords, power-strips, CFLs, insulation, pots and soil.

Money I had saved, because I didn't have to spend money on inferior street-weed, because I had such luck with a 2-plant outdoor-grow. That's what made me decide it's time to do this ourself.
- so I'll throw in a political thought in the whole thing also. The way cannabis is criminalized, too much of it's economic potential has shifted to south of the border. The United States cannot afford to finance the flow of money out of the country, to get inferior weed from Mexico.
It's patriotic to grow. By growing locally, the money stays in the community. Mom and Pop makes a few bucks, everybody is happy.

- Back to LED - any good ideas?

With those LED did they say how much of dist. you should stay away from plants? The light I am using, the plants like it around 6". I think yours is looking good.

Well, the manufacturer suggests 3 to 7 feet or so, but I'm not even going to try that. After I backed off some - to about one foot, it seem as if new growth is coming in with better color - and I just counted 10 babies, also under UFO LED, and I'll post more pics as soon as they show real growth.
Anyone interested in trying out LED for their grow, may check this grow out from time to time. I'll post pictures at least once a week, so that you can all get an idea of what to expect from a 'bare bones' LED set-up, and I have both babies and flowering plants.
Questions and comments are welcome - as well as advice and pictures of your own experiences with LED - good or bad.

OK - new day. Took a few pictures of the babies. They're under 24/7 LED, and seem to be doing allright. Not too much stretching, and I can tell they're growing from day to day.
The way I have set it up, I have to go into the room every evening, and close the 24/7 light section, from the 12/12 section, as they are in the same room, and I have it masked off to almost 100% light proof.
The 'bloomers' are stretching and looking fine also. I know the red color from the LED is a pain in the ass, but when you use it, you get used to it - I almost don't notice anymore, but I can see the pictures are really red. For that reason I use CFL to make it more agreeable to the eye - but as one can see, the LED overwhelms the CFL
I mention that, for those who still think LED is not bright. The newer LEDs are bright as all hell. When I go turn on my grow-room in the morning, I keep my eyes shut.

I don't think LEDs are better than HPS, or CFL for that matter - they're different, and fit different uses. This thread is for good ideas - or results, on the subject.
I know you're out there.

Hello again. Somebody is still cruising by this thread. Hopefully it'll inspire.
I had read a shit-load of Redmans bubbleponics, and had begin thinking of it, and today I gave it a whirl, just to see if I can get the principals right. Seems to work OK. Bubbles really good, and flows fine. Maybe dirt and clay pots are an unusual combination, but that's what I had at the time.. I'll figure a way to let the roots out - like crack the pot a little.
Had some comments about the light in the pictures, so I used a fairly powerful flash in some pictures, but you can easily see the LED light also - which tells me, the light is pretty strong.
Anyway, just doing some 'shootin' from the hip' growing, using LED in the process, to see if it can be done. And then, can it be done for regular people, without a ton of equipment and all sorts of knowledge?
I'd say yes. If you can grow anything, you can grow pot.
This thread is to gather ideas of how to grow with LED, and in the meantime I post my own attempt . Are there almost no successful LED grows???
So far people seem divided.
I think it's working good. I have three UFOs - that's all. Below are todays pictures.

After trying out a makeshift bubbleponics-system for two days, I was convinced it needed to be investigated further, so I acquired a larger water reservoir, plumbing parts, hoses and pumps. I noticed in Redmans exceptionally thorough tutorial on the subject, that dividing the waterflow into each separate pot, can be tricky - so I invented a new system.
Instead of using a waterpump I use the airpump to lift the water, thus eliminating one part.
I have to add that although I eliminated the waterpump, I had to add another airpump to make the system flow properly. It gargles and gurgles a lot, but seems to work A-OK.
I also use a waterheater so I can keep the water in the 70s.
If the pictures doesn't explain my set-up well enough, I'm happy to answer any
questions.
- the page will not let me attach pictures - let me try again.

Wow - I'm so glad I read up on bubbleponics by Redman. Although it took forever to read, one must agree it was thorough. Also, the good spirit with which it is done, comes through.
Back to my own thread. Maybe I should have named it 'mini-grow on a shoestring', or 'innovative mini space grow' or something more catchy than 'LED grow'

- led is new to me, so I thought it would be interesting. First time I turned one of those 90w ufos on, I knew this would work. Compared to those miserable little 225 led/30watts panels, this was bright!

I have three of them - the ufos, and I might want one or two more, for my 6 square foot growing space . It just makes it much easier and cleaner than tons of wires, plugs, extensions, reflectors and other shit for all those CFLs.
I use those also - but by the time you have rigged it, you go - well - I could have done the same with a 90w ufo - with only one wire.

So the light is a little unusual - to your eyes, but to my own surprise, I quickly adapted. Now, I can hardly tell the light in the growroom is red anymore.
And it doesn't look green in the house, after you've been under the led-light for awhile, either.
The brain compensates for it, to some degree - another good trick is to blend in some CFL light - it makes it more agreeable to the eye, and the plants like it also.

Hi KenWood. Yeah - I couldn't figure if beeker74 was just so friggin' impressed that he had to call on higher powers, or that he mistakingly thought this was a religious thread.

Besides I looked up his threads, and I can't tell if he's for or against LED. I wonder if he knows. One moment he seems to think it's the worst ever, next thing he's growing with it.
Anyways, my babies are doing just fine - looking better every day - and my bubbleponics setup is gurgeling along just fine, and the clones I stuck in there seem to be OK also.
More pictures later. Happy growing.

Everything is running smooth. Temperatures and humidity are OK. Plants are stretching and filling out after having been under 12/12 light for 19 days. Since I don't know what I'm growing, I don't know what to expect - as this grow is a test run.
The bubbleponics is gurgeling along just fine, and the 5 clones I put in there are hanging on, although there hasn't been too much growth yet. The small plants are 19 days since seed.
Just took these pics.

So how are things going? How many days are you into 12/12
