LED grow lights... input please.
I have seen LED's compared to HPS 400w, and they're almost identical.

LED grow lights... input please.
Thanks for the link. Very interesting, but I don't undestand why the guy has the LEDs 3 feet from the plants. One advantage of LEDs is that you can put them right next to the plants, for much better growth. He's producing scraggly looking plants, but he is experimenting, and he is getting buds. He needs more LEDs and he needs to have them closer to the plants.

I don't know anything about that first one except that it looks terrible for weed farming. Is it even LED? Assuming the 2nd one is in the proper wavelength, then yes it will work well. You would probably need 20 or so to grow a plant, and 50 or 100 of those to come close to equalling the yield of 400 watt MH. Just a stab at it.

im not too sure but if you look at the base of the babies it appears that the beam itself is only just spredding out enough to cover the entire plant. its my opinion that the reason he has them so high is inorder to have his lights cast a beam wide enough to cover it all? and did u see the end result? the size of the buds was very small as was the total amount.
kids ive been watching this whole LED thing for a really long time and for whatever reason NO ONE is posting any math formulas (in relation to abount of useable light required - per ft squared) ) / nano meters (to determine which of hundreds of types of LEDS to use - even within the red and blue wavelengths / lens types (to determine the spred pattern so that lights may be hung at the proper height) what we need to do is CONTACT some of these LED vendors and invite them to either post their addys here and researching specs in thier literiture or post INFORMATION..... maybe even make it known to these vendors that those who comply with our requests will be the PRIMARY suppiliers to the DOZENS of comsumers that are willing to invest HUGE amounts updating our rooms from this very site???
this is somthing that has to be done because i dont know about everyone but i do know that electricity is killing me costing me an extra $250 - $300 a month not to mention how much is being wasted just to COOL a room because of the intense heat generated by HIDs. all i know is that if any of these manufactures were to put out info id read it and if some were conflicting then id read it all and average out the #s...this has gone long enough what we need are some hard facts

There are LED's that shine in a wider angle, thus allowing you to get them close to the plant. You could get them close to the plant with non wide angle LED's too, you would just have to use a more reasonable amount. This is extremely necessary as the intensity greatly decreases as you move them back.
I agree about getting some numbers down. LEDs for weed farming is such a new concept it hasn't been thoroughly studied and documented. Ziggy, wanna be the first? I wish I could but I just don't have the time, darn it. I got a few numbers, but not enough for a real grow.
I still am waiting to see an LED grow that produced buds of any significance. I have no doubt that a person could get some decent bud from LED lighting. In general people are going about it wrong, and they refuse to spend any money to boot. At this point the initial set up would be expensive as hell to get one plant to bud nicely, but it can be done. Due to the life expectancy and low power draw, very soon they will become viable. Perhaps even today.

LEDs are nice. Low heat, means less A/C bill. Plus they run very low power. So less electricty used. They save money and grow some sick plants because you can perfect the color spectrum to how the plant works.
