LED growing- An instructional grow log

[Opie Yutts]

i need some help here WH, opie, mvp, rock...or someone whos been growing a while, cause ive never seen it. it looks like one of the planys self topped....its only 3 1/2 in tall, on its secong et of 5 leaves..its sprouting 3 instead of 2...all three with full stems....wierd? i tried putting the pics up...but sites pooping on me again.....
ill try with the pics a few more times

If it's never been damaged, that's a little weird. Not totally insane though. Especially indica varieties will do that sometimes.

The LED's I am using are: 5mm ultra bright
470nm-6000mcd-30mA-80mW
640nm-8000mcd-30mA-80mW
660nm-3500mcd-20mA-70mW

1000+ LED's can produce approx 80W. So 6 of these panels could make alot of watts for LED lights.

And thats before overdriving them. I can ovedrive up to 100mA, but gonna start at 55mA. So there is more light there. and if i pulse the led's i can cut the power by 90%!! so only use approx 8W power instead of 80W.

[physicsnole]

The LED drivers supply up to 55mA per channel, and there are 16 channels. each channel is a series of LED's. The max voltage the driver can handle is 36V, so now knowing I can string different colors in series (i had read that you can, and then i read you cant so i was just making sure) I can have approx 12-15 LED's per channel (depending on color ratio). So 1 driver chip can drive 190-240 LED's. 5 driver chips will be more than enough for 1 panel.

Cool, looking forward to seeing the finished product, and to seeing the nice big nuggets you produce.

http://ledshoppe.com/Product/led/LE1003.htm 500 blue LED for 20$

not bad considering brightness of 8000 mcd and 6000 mcd, respectively

damn upload pics thing is pissin me off, this is cool shit and i want you guys to see it....lol
im still not getting how you will need that man LEDs.....if they we CREE class 2's, 1000 LEDs would be 2kw of LED...isnt that kinda overkill?...just askin. whats your opinion of the procyons we are using?

wait till you guys see this suns pics!! the are going nuts now man:jointsmile:

I looked at the procyone and the only reason I turned away was because of the price. The cree xlamps are very nice, but much more expensive than 5mm LED's. Especially now that they have the right wavelengths. The heat generated is also a big issue, but the grow light u have takes care of that. The other problem with the procyon is there are only 2 wavelengths, the other two (660 and 425) give many additional benefits that the plant could use. Ive also read you can trigger flowering by shifting the color of the lights from a majority blue to a majority red. have any of you heard of this?

Fellas, check your rep and let me know if you want help figuring it out. Are you sure the problem isn't between the chair and the keyboard? :wtf:

yeah you're gonna need thousands of those based on what ive seen grown from 5mm LEDs. granted you have alot of extras (CO2....) but its really a matter of photons generated getting to the plant. yes the xlamps are more expensive but with the time and labor put into mounting 1000's of 5mm, the heat they'll generate that you'll have to pay to control it seems like a wash.

Not sure about the color shift trigger as our plants are under a 5:2 ratio of red:blue 18 hour days and vegging like crazy

Please do make you're own lights:thumbsup: Wish I had the expertise to do that. Good luck cant wait to see your threadimp:
