LED growing- An instructional grow log

[Opie Yutts]

Hey not bitch'n,, Just that we had already covered the nm.

Uh, actually you didn't. 2 people unsuccessfully went back and looked through every page trying to find where you "already covered the nm", remember?

I was just asking for a commitment from people serious about LED grow array development, as to what actual colors they would put in their dream design. If you don't want to share, fine, but please don't send me on any more wild goose chases. I'm not trying to be a dick, but I'm not sure if your last response was an attempt at answering my question, and I just don't understand stuff like "I think we get a small 200nm to 270nm ultra-v-white-clear"

SnS, physicsnole, thanks.

Hatch, I guess I was looking for something like this. It's based on the several days I've spent on and off, trying to figure this out. I've read charts, graphs, forums, articles, and results of experiments, until my brain started oozing out my eyeballs. As far as I know, there's unfortunately nowhere that comes right out and says, "these are the required wavelengths and percentages thereof for an optimum LED weed grow array". It's not for a lack of looking though.

UV: 275,290,310 5%
Blue: 412,440,470 20%
Green: 499 5%
Yellow: 566 2%
Amber: 613 3%
Red: 645,660 60%
Far Red: 730 5%

Until I can figure out something better, those are my dream wavelengths. Would anyone else like to share with the class?

UV: 275,290,310 5%
Blue: 412,440,470 20%
Green: 499 5%
Yellow: 566 2%
Amber: 613 3%
Red: 645,660 60%
Far Red: 730 5%

These are perfect wavelengths Opie...however do you think there is a great enough red:blue ratio? 3:1 will do the job but 4:1 or even 5:1 are alot better for flowering. Also with the UV ranges...I think the only wavelength we need is UV-B 310nm, I think, unless you found that marijuana could use those lower UV wavelengths...just asking.

UV: 310 5%
Blue: 420,470 15%
Green: 499 5%
Yellow: 566 2%
Amber: 613 3%
Red: 645,660 65%
Far Red: 730 5%

This would be my array..:rasta:

tis good rock. i think somehow our grow thread has merged with the LED imput please thread:wtf3: Im the one growing with LEDs, lol...and half the shit on here is hurting my head. This first grow is a test of the procyon and LED growing in general. next grow we can start with altering the blue/red ratios or pulsing, or micro-processing, flux capasitors....blah,blah
ah........bi-polar rant over.......:smokebong:, i feel better now.

[Rock.Steady]

right on man.

the flux capacitor bong always works best for me :smokebong:

opie and physics, have either of you read the article in high times? if they are claiming the UFO is that good, then we are set, cause the procyon is 15w stronger than the UFO with more red too. according to high times, pots P.A.R (photosynthetically active radiation) zone is 380-660Nm. and the reason there are only red and blue bulbs is because of the Emerson Enhancement Effect. which is hitting the plants with very short (blue) and long (red) wavelengths as opposed to the full spectrum made photosynthesis and absorption occur faster. "thus, it may be best for indoor growers to mix opposing wavelengths rather than using the HPS/MH mix."
I know you said you couldnt get to one opie, so im trying to include all the important info in here for ya....lol. they actually took 4 clones and put them respectively under a 400 MH, a 400HPS and an UFO LED light. and the UFO yeilded 12% more than the MH, but 5% less than the HPS. (hence HGL adding more red to the procyon).
Now for a written explantion that opie didnt get from someone else. I had to find this in writing before i put my 2 cents in opie...lol...In the trials there was a markedly different potency level with the LED light.SPECULATION is that the shortage of wavelengths aided this process, as abnormal stresses have been known to increase resin production.
So, NO ONE knows the reason for sure, but the final outcome of High Times test with the UFO against 400MH, 400 HPS was this. LED was more potent, 12% higher yeild than the MH, and 5% less than the HPS. in terms of grams per KwH consumed though, the LED yeilded 4 times the rest.
Part 3 of the article is out, Ill go get it tonight or something. If this answered anything opie, im glad...lol...know you have been trying to find stuff out, just tryin to give you facts, and not opinions. that why it took my a lil time to answer stuff.
I will have some pics up tonight also, i am excited for you guys to see them. the plants are actually shorter than they chould be. which is the opposite of what we thought would happen. no stretching at all. and there is massive lateral growth for their height. so i raised the lights up, cause i need about a foot more in height if i wanna start flowering the end of next week...lol

How do I start my own thread thing? I dont have alot of money so I am trying to go with the cheapest setup that will still be successful. i just started 2 plants, they are about 3 days in and have sprouted but i dont know if i have enough light. I have a 75 watt fluorescent tube that im using but im not sure this is enough. any suggestions on what to use that isnt very expensive that will still be good? i was thinking about buying two CFLs (one for each plant) would that be enough light or would i still need more?

[SnSstealth]

go to the grow log area, and click start new thread. how big is the grow area? whats your medium? CFLs will work for 2 plants. Id use 4 for 2 plants, depending on the size of the grow area, is it closed off?, reflective material? need more info man

[dankleader420]

im using my closet i have them on a shelf that is about 1'x2.5' and about 3' high. the walls are painted white, and i hung a blanket up to close it off.

idk if that worked^ but thats a picture of my setup.

[SnSstealth]

holy hell man....shrink the pics next time...and how did you get that pic in there with only 5 posts? anyway, if you are only growing 2 plants, you should close the area down. way down. or add more plants...i love tall multi branch plants in soil, so i only have 1 plant per sq ft. 4 CFLs will grow those 2 plants fine if you close the area off more...but for using your whole closet, you will need at least a 400HPS....IMO
