You can veg with a good LED lamp. In my experience its about a watt ratio of 1:2, as in, a 100watt LED works about the same as a 200w HPS. I built my own 112w LED and vegged with it for 6 months without issue. A friend of mine has the Procyon 100 and had great vegging results with his light. But the prices put them out of the reach of your average cottage grower.

Yeah right... LEDS there fake...its a joke !! 300 watt Leds there $4000 and about equal to a 100 watt Hps set up! great for lighting your bedroom at night,

sigh...

here it goes.



That'll flower something...

40 watts a sink,
80 watts a foot.

I have just learned that thermally I can even do 50 watts a sink...

Is that powerful enough?

I would agree with this, as far as making sense.

You're way off, if anything your numbers are backwards. 100w of LED = 300w of HPS.

And the LEDs last minimally 50,000 to 60,000 hours, reasonably. 8550 hours in a year. Running them 12/12, that's over 10 years of service. Which would be like $500-$1000 of high quality(HORT/AGRO) bulbs. And 2-3x the power to run them.

So, really, if priced around $500-$1000, it might not be such a bad deal.

Mixing LEDs with fluoros(CFLs) is a really good idea, FYI.

What are the total watts used in those pics? Did you bud with them, if so how did it go?

LEDs work... they run cooler... are more efficient.... and will even flower and grow bud

BUT.... and this is a big one..

the technology isnt there for them.... even if they are more efficient, they dont touch HPS lights when it comes to flowering.... and ya you can veg with them... but your stems wont be as thick as they would be with HO floros or MH...

LEDs have a place... for a one plant personal grow... or a few plants if someone can afford them... but for large crops and larger plants, where theres a lot of area to cover, canopy to penetrate, and light intensity is needed to penetrate through the plant, you need HPS or HO floros... i use satellite IV floros now to veg and flower... but now that i switched where my garden is im going to invest in HPS lamps.. i did a lot of reading and research because i was going to drop the money on about 6 supernovas from hidhut... they claim one 270w LED ($$1300) outshines a 1000w HPS... so obviously i was VERY VERY serious about LEDs... and ive since changed my mind after countless hours of reading articles, watching grows online, reading forums and user comments... right now LEDs just cant compete... eventually they will be the standard.. until scientists invent some other form of light producer that is 20x more powerful than the sun and can be seen a mile away and on and on... right now HPS dominate the ability to flower indoor... thats bottom line... LEDs will work, and will produce bud, but their claims of a 90w LED preforming like a 400w HPS are bogus, false, not true, and for all matters at hand a big fat fuckin lie... you need about the same wattage of LEDs are HPS to achieve similiar results... some plants seem to yield better in LEDs than others so i can make that a solid statement... but i can say that HPS is better than LED for flowering, LED is more efficient but will produce a smaller harvest with much much much much smaller buds... hps vs led could be the difference of a pound big large sexy buds vs 10 ounces of baby pop corn buds...

That is burning 314 watts of rebel red.

Flowering something with it... eventually. Probably in a month or so.

I am quite excited to start a journal, just gotta establish sum mums to get to the cloning stage.

Rooting is slow when you're watching!

p.s. go read the experiments at the cutting edge posts by squ1rrely, its Ed Rosenthal talking about his work in the led frontier.

Makes me depressed. Im trying to get a grow going on my LEDs. So much bad hype on LEDs. Im trying not to be bias but this article is TOTALLY bias. The while light to mass is nonsense. It does happen, but not on the scale that this dude is thinking.

Growing a single plant is good with that. Growing a SOG is not practicle.

Im no "engineer" (its funny how many college graduates call themselves engineers when really you need a degree to be one), but if something gets really hot, it means that there is a loss of energy. What we are looking for is how much energy you put in, how much light you get out and how much heat you produce. Lets power a 100w array. How much heat is produced. Touch it. It will not burn you. Lets say we find any sort of way to produce light, you decide. Lets say that the system draws the EXACT same amount of power (power = current x volts) as the LED array. Will it get hot ? Yes, I can safely say that when it comes to efficency, LEDs and CFLs are in the same ball park.

When it comes to growing with LEDs, or growing in general, I can say that I am inexperienced. This is my first grow, with an LED system, and im getting results. It works, but how well I dont know. That is what Im trying to find out. Im not trying to be bias at all. I dont see what the problem with LEDs is. I know they lack the intensity of light, but all you have to do is buy MORE.

As for "no peer edited articles on LED growth," last I checked, it is illigal to grow our "tomatoes" in the majority of the world. Hence, there is no peer edited papers on the subject. ALL PLANTS ARE DIFFERENT. I can grow weeds (legal kind) with LEDS but I cant grow certain herbs with the same LEDs (I havent tried but im just trying to prove a point). He even stated, Algee and land plants are different. Until someone can confidantly say, "This spectrum, to this spectrum works for this peroid at this intensity, and this spectrum to this spectrum for flowering" then there will be NO peer edited papers on the topic.

Whats the difference between a person taking vitimin C suppliments and a person eating an orange? Vit C is Vit C. Does not matter how it is made or who made it. Light is Light. Find the spectrum that we need. We can isolate spectrums with LEDs since they are monochromatic. You cant do the same with any other light source efficiently like LEDS. I heard green spectrum is a waste of light. All other types of light produce green in their white light. LEDs dont have to.

As for price. THEY ARE EXPENSIVE. To change an LED, anyone can do it with the right tools and guidance. I know LEDs on paper, but I didnt know LEDs in real. I have built an array. Not rocketscience.

Not all light is created equally. Depending on frequencies and wavelength you're dealing light that can give life, or take it away.

Not all LEDs are monochromatic, the most research being done behind LEDs is producing 'natural-looking' white light, at very high efficiency(beyond 150 lm/W).

LEDs aren't expensive. You could buy a few hundred high power LEDs for around $500(look up CREE, if you're interested, they made the LEDs used by the various UFO models, as well as most serious LED grow lights). A drastic savings over manufacturered LED grow light.

P.S. Not all vitamins are the same compounds. Usually the higher quality vitamins are in one of the best forms for absorption, while cheaper forms basically don't do jack except get pissed out.
