LED grow lights... input please.

Here are some updated pics as of 09/29. They are still under only 2 small arrays that you see above. I have 3 & 4 almost done, just been lazy. In the comparison photos, the ones in the large pots were transplanted about 4 days before the photos ~09/25. I will be transplanting the LED one's soon.

I must tell you the the 400w mh ones are growing much nicer, but they do have a better environment to grow in. They temps are better and the light is much stronger. But I will admit the LED ones look pretty good to.

I will take more photos tomorrow.

road runner>>> where did you get the machine to pulse?
and i read through japanese study that the pulsing is best at
200~400(400 being the best)μs.
so why don't you give it a try when you have time.
it increases the growth by 20% or so.

if anyone is kind enough to hit me with the info for the LED and Pulsing machine
e-mail me!!! [email protected]

I read this whole post and was worried....at first about the liddy-biddy LEDs the original guy was thinking, then it got worse with the grow/joke shop novelty LED bars, o-ghay-sis liddle array things - which are cool as supplements, or for that hightech application next to the office fish tank.

Some ghuy even said the only LED horticulture patents were owned by the toy company. HUNDREDS of LED horticultural patents exist - in the US alone!

Then people started talking about the Luxeons, which is the here and now of the LED horticultural edge (until the new Cree ones are out). First, for the completely ignorant and/or dogmatic, you're right. LEDs (as we knew them) aren't particularly great for growing.

But Luxeons, technically LEDs - Actually CLASS II LASER DEVICES - are completely suitable and are WAY (not "whay") better than the toy factory lights

Yes the Luxeons do work, and awesome. Sure you need a combination of blues (royal and regular) and reds (mostly reds, maybe a couple of red-orange, but more amber than red-oranges) to get the whole thing down, and the wiring is easy. Just practice some quick soldering.

UV ones only have NEGATIVE connotations to growth.

Just to buy the lux. stars, wire, and put on heat sink (as structural component) isn't so expensive. And if you compare the up front cost with the cost of ballast, bulb A and conversion bulb B, then the heat/ventilation issue.... and driving to the grow store, ordering through the mail...

Well, if you were cloning and using HID over LED, you' be plain stupid. Like dial-up versus broadband stupid.

I KNOW there are people who use LEDs such as Luxes, with awesome results, that's already a fact. Anything less than the Luxes really isn't worth doing, from a practical do-it-yourself view.

But I'm sure it's fun.

You should see what these things do with Masterlow and Lowryder strains!

And remember the code, never show pics of your finished LED grow! Ever!

Why is that?

Um, yeah... why no pictures?

Pictures make us happy... happy people.
Just ask Garden Knowm.... he looooves pictures.
Heck, you could put a picture of a seaLion in the middle of some hydro pics, and he'll love it!

RE: LowVoltageNerd, roadrunner, and PearlJamFan
THANKS for the updates!!!
Very inteteresting to see these experiments.

Peace everyone,

Yea we need pictures..

or is it just bat guanno. . lol :rasta:

i agree with everyone else, if you dont have pictures to prove what your claiming then your full of shit.. ( no offence ) but proven methods should always be shown, one to spread knowledge and help new growers and experienced alike, and second to prove that your not just making it all up.. cause i dont believe you untill i see a setup and a plant growing under it..

although i think exploring LED growlights could be very important and cost effective, but with no information or good reviews obviously either not enough people have tested it (which i doubt, people seem to test anything that would even yield a .5 gram more than what they are using), or it just doesnt work.. please prove me wrong if this method is so great

Most of these grows are done with 100 watts or less. Speaking of which, I wanna see a grow that matches the wattage of these other lights. Any growers out there with deep pockets that wanna contribute something back to the growing industry? Use the same amount of plants in a plot and compare a 1000 watt HPS with 1000 watts of red and blue. Since blue isn't up to spec maybe 800 watts of red LED + 200 watts of blue CFLs, or whatever ratio is optimal. Maybe 200 watts is more then the plants can absorb, maybe it's not. I don't know. A small amount of UV in there as well. Not to much though, and not focused in one area.

Dude idk man...your still not getting the picture..the whole idea of using leds it to cut down on power..a 1000 watts of leds...oh shit that would be a ton...u wouldnt have enough space...unless your running high watters ....the whole idea is too keep power down and wasted heat/light and plant intake of needed NM's up...

...your still not getting the picture..the whole idea of using leds it to cut down on power..a 1000 watts of leds...u wouldnt have enough space...

Some people seek maximum yield for their current power use. They are not seeking to reduce their power use.
If a 1000W HID gets you 2lbs....we want to hear some miracle statement like "1000W of LED can give you 4lbs". If it took more plants and more floor space to do so, I'm sure many a grower could accommodate it for the extra yield

Okay, could someone give me some guidance here.

I have extra time and no real life so this sounds like something I would like to try.

If you were going to start experimenting with LED's where would you begin?

What kind on Red and Blue led's should I get? What are the spec's of these lights and how many do I need?

I would like to make this simple. What would be the cheapest way to experiment with LED growing.

I would like to try this but links to NASA and technical papers fries my brain. Make it simple people. Kinds and spec's of lights needed for a experimental grow. How would you do it?
