I am attempting my first grow and would like some info on LED's

I will be growing in my closet and i wanted to ask about what i will need.

I wanted to devide it into 2 and have one area for veg growth and one area for flowering. What LED's are good for which? i thought that it all depended on the cycles i give the plants (18/6 for veg and 12/12 for flower). If this remains true, could i use the same LED for both of these? I wanted to buy this light :
We use only the highest quality BridgeLux LED's and SemiLEDs chipsets - Each LED outputs 1 Watt! Most importantly, our LED Grow light have the most efficient spectrums in the market - 660nm Red and 460nm Blue are the exact spectrums necessary for the best result of photosynthesis. Additionally, our Warm White LED's provide powerful wavelength (6,000 Kelvin) to cover any missing spectrums! Your plants will fully absorb the wavelengths for photosynthesis. Our LED Grow lights are the finest units available today, utilizing every bit of energy and providing optimal results!
Days of large bulky ballasts, cooling and expensive electricity bills are over! Each unit is equipped with three intercooling fans to keep the units from overheating. Our units will never overheat, therefore never scorch or damage your precious plants. Larger MH / HPS lights require cooling systems, ducting and heat exhaust fans. Now you get everything in one simple package!
If you've done your research, you know that the combination of Red and Blue LED's are the most effective settings - The Powerful 6,000 Kelvin Warm White LED's will cover any missing spectrums! Other models offer poor wavelength settings that are not the exact 660nm Red and 460nm Blue peaks absorbable by plants. Photosynthesis is achieved at these exact color spectrums, and our model offers the optimum wavelengths for the best results. You can find NASA study results regarding these spectrums online, which reference these exact specifications!

There are a lot of new players in the LED grow light world. There's no way to keep up with every little mom & pop setup out there.

I only know one brand of LED that really works - and I work for the company. So, I'm not unbiased. But, we are also the only people offering a 90-day satisfaction guarantee and a 3-year warranty. No one else will stand behind their product like we do.

The link is in my sig - bottom right.

There's no reason why you can't use that light for both veg and flower. BUT people will tell you that you get better results if you flower with (insert favorite light here). In other words, results may vary and you may very well be getting ripped off (or not)!

I like the fact this company advertises the LED frequencies. Since ProSource makes a point of NOT disclosing the frequencies I get the feeling they don't use 660nm LEDs.

What matters are results, not specs.

Just my $0.02.

Im goin need some serious didge to buy LED's

Well, after looking into this matter more and more i realized that i do not have the money to shell out for a good LED grow light, so i went ahead and made a CFL grow box. Used the schematics for the rubbermaid stealth box( Awesome by the way !). Will post up pictures soon of how the grow is going. Have 3 seeds so far, germinated and starting to grow. They are a Lemon Skunk strain that i got. Hopefully i do not kill them and then i can try out a better strain next time. Wish me luck !

what's the avg. price for these lights?

The best LED grow light I know of is the 180 watt Jumbo UFO. It's $700. That sounds expensive, until you do the math. They give off no heat. So, there's no cooling and venting expense. They have no ballasts or bulbs. So, you don't have to replace those. Plus, after 11 years of 12/12, they still have over 70% of their original intensity. So, really, if you look at it as 11 years of flowering in a 2' x 2' area for $700, it's cheap.

I am not expert on the topic but I think there might be a few issues. First high power LED's do produce hear and many even require heat sinks. Im sure its not anything compared to HID lights but some heat is created.

Second, I agree that LEDs will last a LONG time but judging by to constant development of high power lighting I would bet that in a few years there will be much better LED lights available. Of course you could keep using your current light but the desire to upgrade might be too great. I would be a bit more conservative and say 3 - 5 years would be a more realistic lifespan for current lights.

I might have an advantage, in terms of availability of information. I work for the company that makes the lights I'm talking about. So, my opinion isn't really my opinion. It's a product feature. We also have the only 90-day satisfaction guarantee in the industry, as well as as a 3-year warranty.

Gee... that kinda turned into a sales pitch. LOL

I guess that's what happens when you have a good product. It makes you excited.

I know you work for the company making them. So the LED light don't produce much heat at all? Do you guys use all 1W LED's? I have been meaning to corner you for some questions lol, you should stop by my thread.

Also, I still stand by my claim that the realistic lifespan of any "cutting edge" product is limited due to future developments. Does that mean that you cant use the light for 12 years, nope, but you might not want to.

Bulbs for HPS are $70 - $100 for good ones.

Just the cost of bulbs for a few years, alone, is more than the cost of an LED light. That doesn't include the cost of cooling and venting and replacing ballasts, either.

So, they are substantially less expensive to own than any HID set up.

As far as heat goes, we have to heat our girls, not cool them. They like 85 degrees - a lot.

The "good" HPS bulbs that retail for $100 emmit 90% of initial lumens at 50% of their rated life. The average rated life for these bulbs are 16,000 hours. So @ 8,000 hours you are getting 90% initial lumens. 8,000 hours of 12/12 is 22 months of operation. This is why I change my HPS bulbs (Eye Hortilux 600w Super HPS) every two years. I resell my old bulbs on craigslist for 30 dollars, and buy my bulbs in cases, 6 at a time for about 80 bucks each.

What it ends up costing me is 50 dollars per light, every two years.

I was always under the impression that they lasted two cycles and they start crapping out on the third. Mine always did, anyway.
