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.

They look fine, don't worry for now. I just have my doubts about LED lights being more efficient than anything else. But I'm open to it if it DOES work.

This looks good crispyfried .Will be intresting to see how this grow goes.They look a bit slow for 2 weeks but look real healthy.What strain is it and have you done some research on these led bars.? What is the purpose of adding the red light? Sorry about all the questoins but im intrested.The Postman.

The red light is good for when the plant starts flowering and preflowering. If this does work, the plant will grow like a madman when on 12/12

The bars are from solaroasis and other sites, and they claim that each bar is equivalent to 100 watts of HPS, but judging by the somewhat slow growth rate this may not actually be the case. The red LED bulb is just another type of LED grow light that's available online. And it seems that I needed some more light anyway. I mixed up all my strains in one bag, and I bought a bunch of different ones, so they could be almost anything, such as regular afghan to white widow to that california orange strain.

Plants are slow under hps aswell, I got a feeling that they'll explode with groth when you switch too 12/12 later on.

So they come in red and blue and i take it that cannabis comes under a high light plant.Just had a look at them on the link you mentoined and they seem to think that they are good so it will be real inbtresting to follow this.Could you add more blue for veg and more red for flower.The Postman.

The solaroasis lights just have their standard mix of bulbs, so you can't adjust the blue and red, but this other company at ledgrowlights.com sells only red or blue, so then you can adjust them.

What kind of plants are they? Maybe I can give you an estimate bout how high they can get in there.

Looks like your plants are having enough light, cause they're not streching.

Crispyfried
04-27-2006, 05:42 PM
I'm not sure what strain they are. I mixed up at least ten different strains in one bag, and chances are all three are different strains.

Crispyfried
04-27-2006, 06:08 PM
It's not so bad because I only wanted healthy plants, not a particular strain. So I planted a variety in order to select out the healthiest seedlings. Then I may breed these and produce plants that do well for the given conditions.

But there's a huge differance in plant height. Haze for example is normal too grow fairly high. Now If you take a PP (powerplant) those will stay faily small but wide.

Well guess I'll find out the hard way. Althought two of the plants are a lot shorter than the middle one.

Yeah the LEDs really seem to work. If I didn't have the 42 watt CFL in there there would be no doubt, but that CFL helps to eliminate odors so I've gotta keep it.

WOW crispy thanks for sharing.. I think a lot of us have been wanting to see these puppies in action.. Growth in the first 2 weeks is always pretty slow... But after day 14-17.. the plants should really start to take off.. The stalk should start to get thick and the plant should get bushy...

please keep posting pics...

It does not look like you mixed any perlite in your soil...?

thanks again..


one more thing.. GET tHE LIGHTS closer if you can.. They should be nearly touching the plants...

Yeh keep posting pics as this will be a real intresting thread. i done some reading up on these lcd last night and they sound good on paper and they seem to be doing there job and as knome and britewire say they should take of after a week or 2 and they will take of during flower . Best of luck with your grow and i hope it goes well for you.the Postman.

There's some perlite in there. The mix is mainly coco coir with wormcastings and perlite, also rock phosphate, starter fertilizer, a good amount of volcanite, trace mineral rock, and I recently added some Super Tea to the top of the soil which probably covered up some of the perlite.

Yes, you have to move the LED's much closer 6" or less would be optimal. You do not have to worry about any type of heat problems with those. LED's do not put out a lot of light at 14" away. The plants would really thank you for it.

Crispyfried
04-28-2006, 04:57 PM
Well with my setup it's a real hassle to adjust the LED bar array, but I'll let them grow up to the lights until they're touching them before I move it higher.

Yeah I moved the CFL and the red LED light closer. I also pulled the right-side plant as it wasn't getting good air flow, but I added some new seeds to the soil so I'll have some additional plants in better locations.

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.

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.

Opie Yutts

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.

Looks like the light isnt covering pointing at the most efficient angle, half the plant isnt covered.

YOU can put the LEDS as CLOSE AS YOU LIKE because heat should simply NOT be an issue and the penetration isn't that strong on LEDs so the closer the better.

otherwise, looking good, I too am very interested to see the results.

The lights in the photo are just supplementary, there's an array of four LED grow bars 7 inches above the taller plant.

I admit I was impatient in my similar post and didn't look carefully enough. I am so glad you are running this experiment we are all rooting for you and your LEDs let's hope they come through in the flowering stage. So are you using 5 or 6 bars? Four from above and then two supplementing the sides?

Well the two plants have been under 12/12 for six days now, and the one that's in front of the Buddha seems to be doing quite nicely. I can't take a picture right now because they're in the dark. If the bigger plant is a female I'll pull the smaller plant and move the one CFL out of the main compartment and just use LEDs for the rest of the grow. If the big plant is a male and the smaller one if a female, I guess I'll do the same thing for that plant, but I'll also have to bend it towards the center of the growing area so that it grows under the primary LED array.

Crispyfried
05-07-2006, 12:30 AM
I just pulled the smaller plant because it wasn't growing much. I really hope that the one remaining plant is a female. If not, I'll have to start from scratch, but at least now I know how to grow properly with LEDs. I'll post a new picture when I find out the plant's sex.

Crispyfried
05-07-2006, 02:36 PM
So yesterday I noticed one very early preflower, but no hairs, so I'm hoping that it grows some hairs soon. It currently does look like a ball on a stick, but from what what I've seen posted about preflowers, it may still turn out to be a female. I'm going to go get a magnifying glass so I can more fully examine the preflower when the lights come back on tonight.

Crispyfried
05-08-2006, 01:53 AM
Well sorry to say that my one remaining, quite healthy plant is a dude so I yanked him. This unfortunately means that there are no plants left for my LED grow. So this grow is over, but I can say that the plants seemed to do fine under LEDs with one 42 watt CFL. But it does seem that it is important to place your plants directly under the center of the LED array. Dunno when I'll have time to start another grow, but I'll continue to use my LEDs.
