LED grow pictures

Sounds interesting, keep us all updated any more pics yet?

Legalizdahurb Reviewed by Legalizdahurb on 04-29-2006. LED grow pictures So these plants are about two weeks old, germinated in custom organic soil mix under 200 watt CFL, then put under four LED grow bars and at first two, now one 42 watt CFL and as of yesterday an additional red LED light over one of the plants. I'm a real novice and haven't ever completed a grow yet, so tell me how my plants are doing. Rating: 5

I got a couple of those Oasis led strips myself, they dont seem to do much other then supply a small amount of supplemental lighting. Anyone wanna buy mine? I only used them once..

Care to share more about your experience with the strips? How many plants were you attempting to grow under them? They definetly don't look as bright when shining on the plants since most of the light is absorbed. I'm hoping the new professional bars will be a bit better for flowering. They are working just fine for me now but time will tell whether they will actually do the job adequately or not (I got my 250watt hps on standby just in case).

I am pulling for you but I am skeptical. It looks like those plants are pretty healthy at this point, but I agree that the lights need to be closer. The main advantage of cool-running lights is that you can get them close to the plants. I know that almost anything will work for the vegatative state, but I have yet to see pictures of something flowered solely by LED. I have a feeling that the yield is much less than desirable, but like flourescents, with enough of them you may produce some good bud.

I have yet to be convinced that anything is really worthwile for flowering other than HPS. I have however seen pictures of some descent yeilds with flouros, and this may be the only possible exception. I would love it if your grow here would prove me wrong. I would love to tear out my big fans and hot, electricity sucking lights. I would love to see this thread continued to harvest with nothing but LED's, but I completely understand if you must use other light sources.

they claim that each bar is equivalent to 100 watts of HPS
Yeah right. Does that mean while it's touching the plant? Even so, I doubt it.
Has anyone held a light meter the same distance away from these? I need to see this documented before I will believe it. I'd like to see the cost necessary to produce the same amount of photons in a room or closet. Better yet, the cost to produce the same yield. I wonder if this would give the LED's an advantage due to the red light it produces. LED's vs 600 watts of HPS and the necessary additional ventalation. Mano Armanie, man to man, no rules, just photons vs cost.

Thanks a bunch for posting this experiment. I hope it works out great for you and I would like to see more grows using LED's. I have a feeling that they are not economically viable at this point, but who knows, maybe pretty soon...

Good luck.

So I in the name of science I moved the CFL above the main LED array so it's essentially removed, so we'll see how the LEDs work solo from this point on. I also increased the air flow.

Very intresting this crispyfried. great thread.The postman.

If you have something to smoke, that's great that you want to use just (or mostly) LED's. It will be very intersting to see the results. If you're short on weed though, I would just blast them with whatever light you can, especially when they start to flower.

In other words I don't want you to go without smoke just to appease my quest for knowledge.

Please keep us posted. Can't wait to see. I want LED's to work, dad gummit.

And very good job moving the lights closer. This is very important, more so than many people realize. Photon intensity decreases dramatically as distance from the source increases. A way to easily move either the lights or the plants should be a major concern in grow room design.

An update and some advice. My grow box was getting a little cold so I moved the CFL back into the main area. Also, the CFL is over some new seedlings that just sprouted, I may or may not keep any of the new seedlings. The bigger plant that's in front of the Buddha is doing quite well, but the other plant isn't growing much and its leaves may be starting to brown and curl a little bit. This may be due to the custom soil mix and fertilizers that I'm using, but since the other plant is doing fine I think that it may have a lot to do with the plants position under the LED array. As such, it seems that it may be very important for plants to be centrally located under the grow bar array. Given the size of cannabis plants, this may mean that it may only be practical to grow one or two plants under an array of maybe three to four LED bars. I'm going to switch to 12/12 tonight, and if the bigger plant turns out to be a female I'll probably pull the other plants. If not, I'll keep all the plants going and see what happens, just for the sake of science.

I'm really looking forward to seeing how these plants flower under LED
