I haven't seen or heard about secondary reflecting lens thingies on LED lights yet, so that is neat.

No reason to use more electricity than you need to I suspect. That and I had an issue with my seedlings going straight to the LED, they grew more nodes than HPS but were half the size/height they should have been after a month. Keeping my seedlings under CFL for 4-8 days before LED at 2ft does...

You don't have to crater if you have the airpot right side up (you want the end without the holes on top, I always make this mistake with at least one of my airpots each grow ><). Then just make sure its filled to within 1/4in of the top and you should have any leakage Cratering is easy though...

He told me he doesn't think they will put out enough new tech this year that it will change again before next year. But I do believe he is working on a 100w LED and a <100w**(**supposed to be small enough to fit in PC grow box) that may be available before the end of the year, I don't think the...

That is something I think a lot of HID growers never consider. That is the way I looked at it for me, sure I just forked over $1,100 for a 395w light - but it will easily grow enough its first run to pay itself off and then some, (I am willing to sacrifice that upfront $$$ for all the benefits...

This is the kind of talk in an LED thread I like to see. Does anyone here happen to know if any big name companies are developing LED lights/bulb/diodes/whateveryoucallem for growing plants specifically? I mean I know a lot of LEDs are tailored to plant specific wavelengths, but Phillips or...

Yeah I hope it will be a lot cheaper soon. 3w with <100 degree angles seem to get good penetration (better than my 400w at least), I wouldn't start to worry unless a plant was getting over 3ft tall. They made the jump from 1w diodes to 2w, and I think you could say 2011 is the year that 3w came...

Yeah I guess you gotta hope they cared enough to go for a quality power supply as that seems to be the only thing going wrong besides LEDs just dieing out. Normally I'd say going with one of the top companies you could get away with 1/2 as many watts going LED (especially if you SCROG, LST...

It should be cheaper if you know who to call/buy from as far as parts go (factories, warehouses, US/China). But it would seem to me that the people having much success building their own are the people who end up starting their own online LED business (some which are crappy ebay ones, others...

In no particular order, blackstar, isis, magnum, GLH, advanced LED 3w, LG-LED solutions, hydroponicshut pro-grow, apache tech, blackdog, are companies I keep on my list RRLBT420 what is the system and size of your grow you are thinking of when you say that?

Just to point out that I don't work for any one them. Thought it would make it stand out a little more. Oh I guess i forgot to say it would be extra unlikely for someone to work for more than 1 LED company anyway. Wayno30 no it would not be from my fellow salesman, because for what must be at...

If you can give me examples of crappy LED flowered grows, I can show you they were done with crappy LEDs. And I can show you a good grow with a good LED. That would be much better than what you've been doing, you don't need to give examples necessarily, you just need to do something different in...

Well you're wrong. I'm someone who got into LED, found some good ones, and helps others interested in LED or those who it would work well for (as I've gotten through all the crap LED tech and grows that naysayers haven't, I know the bullshit LED from the not). If you read 800 of my posts you'd...

It was $1100 from growledhydro. Its since been upgraded to the 500w model. They cost about $2.9-$3 per total watt, the other company I'd go for would be blackstar 3w panels at $1.9-$2. Magnum, Isis, and a couple others look good to. PS: haha I really like your signature quote thingy at the...

Again wayno30, I don't sell LEDs. Could you please just go away or stop commenting if you are just going to continue and make stuff up about me with your posts? I get that you think HPS is vastly superior to LED, but this is a thread about LED being the future, and me and others believe that...

Well I'm not sure how many are really useful. One point of LED is to not waste power on spectrums/wavelengths that come along with using say HPS. I haven't seen any LED company go over 12 wavelengths, so I think there might only be 12 wavelengths that are useful for cannabis that anyone knows...

I've never seen a cannabis grow journal of apache lights, nor have I seen them from quantum. But I know I've read at least 8 between Irish, SettingSun, and some other people over at 420mag and here with GLH. If you plan to get at least one from each company, I'd go with GLH first because its the...

Well one lesson I learned for sure was this: Its too good for freshly popped seedlings at 2ft, they grow without light burn, but after the first month they are half the size they should be because it was so easy for them to get light they didn't bother growing in size so much as every node...
