Tits up.

So true in so many ways, Joe!

You said;

"no infrared, no ultraviolet, very important for some plant processes to work correctly..."


Perhaps, but for practical purposes, I find that dichroics, (660 and 470 nm.), can do a bang-up job.:thumbsup:
Here's the latest Led Vs Sunlight grow-off.
[attachment=o228065]
G13-BB cuttings.
Sunlight girl inna middle.
The indoor girls are a tad smaller and the outdoor girl had her main cola chopped for bud rot,
[attachment=o228067]
but, considering the container sizes, that's a damn fine comparison for 150 W. of LED.
The indoor girls used half the water and nutes!
They had no rot, no borg and all their trich caps in place with 90% of them cloudy!
[attachment=o228066]
Brought these out in the afternoon.
[attachment=o228068]
4 hours of sunlight "toasted" about 30% of the caps to a nice amber hue without shriveling them.
Then I chopped next morning at sun-up.
One girl got too close to the light and got bleached.
Also stopped growing for a week.

Leds work well with only deep red and blue.

UVb burns the heads off of trichs as they ripen and turn cloudy.

Far red, 730 nm., may or may not hasten blooming, but, so far I haven't found any use for IR.

Always eager to learn though.

Aloha,

my chinse lights seem to be doing fine on my 4' plant. right now i am using a prosource 180w ufo, and that hydro girl gave me a free 126w led light of hers to test out. ill take a free light anytime i will do a side by side test with her 126w agianst my 180w. when the money is right i might also get some TI pro blooms to try out.

but i am very impressed with my 180w 5-ban light. my plants were in 95-100F* heat all their life and they were attacked by spider mites. plus i use to have a 90w ufo that i used for these plants from start to 5 weeks of flowering.

ill let u guys know how it works out for me with her 126w light that she says will blow away all the rest. it must be magic!!! i did use her light for a few weeks on 2 of my plants but took it out of my grow area and just used my 180w. you can see her light in one of the pics on the left side corner.

While we are at this, I will mention to you I have also been using 2 TI Pro-Blooms 600s for the past year. They have the BEST full spectrum light output of any LED on the market. Those 2 TIs together will better a 1 kw HPS, I know cause I've done side by side grows using both.

hey oldmac what watt leds dose TI use in the pro-bloom? what size foot print will it cover? and whats be best higth to hang them at for good pentration? any info on these lights wold be appriated.

also hows the vegging on these lights without any side lighting?

Shake's gonna need this for spam removal.

LMAO!

that's awesome DH! i missed a bunch of stuff in this thread. i've had my kids this weekend and my son spends more time on my computer than i do when he's here! (playing harry potter games, not visiting cannabis message boards though!)

man, this thread got good.

i must say, spams not that bad. fry that shit, throw it on bread with some mustard. well at least if remember right from my childhood.

and damn these LEDs and all their confusing-ness.

They average 2watts per diode, but there may be a few 1 & 3 watters in the mix, I'm not positive.

The TI Pro-Bloom has 150 LEDs; 105 red, 18 blue, 15 white and 12 "proprietary" some of which are UVb, IR etc. (no mention of "sunrise orange").

For photon whore plants like mj, 3'x3' growing SOG, 1 pro-bloom is enough. I'm currently getting ready to launch "fogfognugen" an aero/fog grow system and for starters we are using 2 pro-blooms on a light rail to cover a 4'x4' tray. Ultimately we will use 4 per tray, but decided to experiment first with 2.

They are not designed for vegging, but would do ok probably. I use a 600MH soon to be replaced with 320watts of T5, 4' overdriven to 80w/bulb, for vegging. Which btw I don't do a lot of, I grow SOG. Which brings up my grow philosiphy indoors; regardless of the artifical light used, it is more efficent to grow lots of small single cola plants then bushes. I'm not interested in large plants, with big stems, lotsa branches and leaves because I'm going to throw that stuff away, I just wants buds. This does not work tho if you have concerns about plant count, then look towards SCROG.

What a rip! 40 watts of L.E.Dâ??s for $800?

Looks like you just have six 5-watt stars (or 3-watters) and a 15 watt red LEDengin ($86.44 from Mouser, total) wired to a power supply. Top-of-the-line dedicated LED drivers are only $55. Thatâ??s with current limiting, voltage limiting, and dimming via pulse width modulation, and 60 watts, not 40. So how can you charge $800 for that?? :wtf:

BTW, the following words are all misspelled in at least one location on your webpage: :error:

Heat emission
Reference wavelength
Guaranteed (thatâ??s scary)
Self-sustain
Specific
Technology

That's kinda scary from somebody hawking a homebrew build. Is your product UL approved? CE compliant? Do you have any specific product liability insurance on it?

Iâ??m calling bullshit on your â??patent pendingâ?� claim. Provide a link to the patent info (itâ??s all available on line) or go away. US Patent Office donâ??t like no phony claims.

BTW, spamming's against the rules here. Thanks! :spam1::thumbsup:

DH,

I am finally at a point of building my own light like you did. I had a 1W based model made and it works, but it would be better with higher powered emiters. Would you be willing to email me links to the parts you used to build yours for the LED drivers, contact for the heat sink, stuff like that? It's ledtime @ comcast.net.

It would be much appreciated. Seeing the results you and Weez got I am blown away. Those higher powered emitters work really well. The 120 degree pattern of the 1W doesn't penetrate all that well. Works good, but not good enough.

Thanks!

or just start a thread with all the info (and yes, i know it's in the other one!)! make 'em sticky it and then everyone has it all in one, nice, neat package.

I thought all that info was in;
http://boards.cannabis.com/indoor-lighting/167881-calling-out-weezard-led-advice.html

I'll save ya some drillin', though.

Generally, anything electronic can be had from mouser.com.
And a short e-bay search will turn up heatsinks to burn.
(Got my first ones by cannabilizing an ancient stereo amp)

We'll be hangin' out here:jointsmile: and are always willing to lend a hand.:hippy:

So, jump right in.

Santa Clara, CA - August 27, 2009. LedEngin, Inc. today announced the addition of Far Red products to its high power LED product portfolio for horticultural applications. The Far Red 740nm LED provides record radiometric power up to 400mW in a compact 4.4 mm x 4.4 mm package with exceptional radiant flux density for LED grow lights.

LedEngin Far Red LEDs add to the current portfolio of Red (635nm), Deep Red (660nm) and Blue (460nm) LEDs for horticultural grow lights. The Far Red wavelength simulates seasonal effects and the onset of sunrise/sunset to prolong perceived daylight. This product completes the family of desired wavelengths in the plant absorption spectrum of light believed to enhance plant growth. LED grow lights allow customers to optimize the light to promote accelerated and predictable plant growth while realizing high energy efficiency compared to traditional horticulture lamp sources.

It's official. Ledengin is throwing its hat into the horticultural lighting ring. Looks like the 660's are going to be a permanent catalog offering. They're also real proud of the 40-watt whites they've come out with. Too bad this is just a 5 watter.

ledtime: check out the Mean Well PLN 60 series. Their 12V driver will push 4 red / deep red 15 watters beautifully @ 10.5-11V range.

You need their 15V driver for ledengin 15W blues. You can run 3 hard (18 watts) ea.) or 4 easy. Neat, simple, easy. Hooks direct to the LEDs. CC and CV. All protected. Just mount your leds and connect. :thumbsup:
