Hey Weez,
Are you experimenting with pulsing the lights at all?
Are you going to add any UV LEDs?

Why on earth would I do something that silly?:silly:Quote:

Red and blue leds may or may not produce THC as fast as sunlight does, but the THC accumulates for the whole grow simply because there is no UV to break it down.
Now my meds are too strong! :stoned:
(Poor baby, yah?:D)
IMHO, UVb is just another stoner myth.
In short, don't need it, can't use it .
For the full rant. Check Merry Prankster's thread Bagseed LED grow.
Aloha,

W,
I have requested the spec sheets on those custom made LED's. We'll see what they have to say for themselves, and then test them to see how full of it they are.
Hopefully, they can come through!
Have a ? on the wavelengths in the blue spectrum. The charts you show me say 430 and 452....yet most of these led lights are using 470. What should I really be aiming for?
Aloha O. M.
"HEY WEEZE, I hope you read this....to your plants so they know what theys suppose to do when they see uvb. lol
(Hey it's the main stream media, I don't trust them anyhow) "
At your request I read it to them.
Also read them a study on the effects of UVb on complex organic compounds.
Asked for a show of limbs if anybuddy wanted to hit the tanning booth....
Not a sausage!
Though they did show gratitude for the extra CO2.;)
Dese girls ain't dumb.:D
Most of the misinformation here just gets a smile out of me.
I got less important fish to fry.
People wanna buy Superthive and pretend it does something, that's fine by me,
(did a double blind once, waste of time, made no difference),
but it don't hurt nothin' but their pocketbook, yah?
Dicking around with UVb can blind you, burn your skin and kickstart melanoma!
So, I gotta open my yap about UV before someone goes and raises my insurance rates.:D
Just askin' folks to read and think before they jump on that little me-too wagon.
The rest of the dumb stuff?
Whatevah floats yer boats is alla time fine by me.
Wilder da better I just watch and learn.
An open mind is da bestest kind.

Wee Zard
Most of 'em use 460-470nm. because that's what has been affordable/available when they designed their lights.Quote:

Emerson would be tickled pink.
I'd really like to see that.:)
If not, I'd gun for dead center at 440 nm. with a wide "skirt".
Havin' fun yet?:D
Weeze
I love this stuff....it's nice to get back into scientific experiments. About 10 years ago I used to design heart catheters for a big corporation. Since then I've been in finance.
The exercise my brain is getting from this is quite refreshing!
These guys say they can make these LED's to my exact specs. It takes the cost of my units up by $55 to get the exact wavelength LED, but to me that's well worth it if they work!
I was thinking of instead of ordering their off the shelf 120W light with just the 470's, I would substitute in 50% 430nm and 50% 452nm to comprise the blue in the flowering light. Sound like a good plan?:)
I like it!:thumbsup:Quote:

Here are the links to how I layed out the LED's on the two lamps. Should have them in about 10 days.

On the first link the unlabeled LED's are the 430nm. On the 120W all the reds are 660nm.:)
Here is the test results of the 660nm red 1W LED's that are going into my flowering light:

Organized people are the only hope for us ADD kine guys.
Without my well organized wife, I'd prolly descend into piggery in very short while.:stoned:
From the last 2 years of :weedpoke:
I'd say you are going to be very happy with the bloom light.
I'm thrilled that you are trying the double-hump blue for veg.
I have some 5W. "Royal blue" leds though I can't remember the actual wavelength.
Their skirts have quite a bit of near uv.
Enough to make a blacklight poster scream.
Lights up my T-shirt just standing inna doorway.
But, of course, no UVb.
Plants vegged under it were greener and healthier looking than the ones under 470 nm.
A subjective judgement, not a real double blind.
But the difference was not subtle.
Now, we wait, yah?
Aloha,
Weeze
