Can you confirm that blue LEDs die long before the reds? And if so, how would the owner replace those LEDs?

If the light has to be returned to the factory for replacement, at what cost?

If you have to toss your lights in 6-10 years that is an expensive hidden cost.

Where did any of this come from? I don't see anyone arguing over blues and reds and which fades faster, or if they do at all. So why do you feel the need to put it in here, when you can't clarify or back up your statement? Seems like someone is shooting for discourse without reason.

As far as what happens if a LED fails, WE REPLACE THE UNIT. What cost does the consumer have? NONE. In fact WE PAY RETURN SHIPPING!

I find it funny that you consider tossing a light after 10 years "an expensive hidden cost". How many of you HID guys are still running 10 year old ballasts? How many of you HID guys are still running a 10 year old bulb? So let's see, if we compare against current technology there's not a whole lot of difference going on now is there? The HID requires a $100 bulb every year for 10 years, which is $1000. It's guaranteed to use 60% or more energy than an equivalent LED, so add up that cost over 10 years. Now I wonder if the $475 or $700 panel cost is really going to make that much difference over that much time compared to the bulbs and extra energy consumed by the HID that would have been used. Or perhaps "the expensive hidden cost" only applies to people like you who buy a cheap panel on eBay when you know our lights are superior. Oh well, "you get what you pay for".

hey led girl good stuff you have goin on here. I have been following you for a long time and am interested in your aeroponics sytem. i see your growing some pretty nice trees there. Do you ever have issues with clogging from the sprayers. i wanna cut the number of plants down and grow some pretty big yeilding trees. can this syetms grow trees as big or equal to those in 5 gallon buckets of soil because thats whare im currently I have 2 600w hps and a 6x9 room i would want 2 for flowering and 1for veg can i veg a little longer like 6 to 8 weeks and then transfer the net pod from the veg system into the flowering room. thanx alot any info is appreciated

Sprayer clogging is a minimal issue with our Aero units. We use 360 degree sprinklers that clog far less than conventional sprinklers. Upon occasion (every few weeks) you may need to take a needle and clean a sprinkler or two though. The tallest plants I've ever grown in aero systems like ours were around 6' tall. I quickly put an end to that though, as I could create just as much yield on a plant less than half the size... Needless to say you learn as you do each grow, and the 6' trees were on one of my first. Anyhow, transferring plants from one system to the next is pretty simple. Hydro makes a lot of things easier in my opinion ;)

what do you think of these...
they have a 586watt for $3,200
quad bandwidth
http://www.stealthgrow.com/products.htm#SG1202

Well, at $3200 you're paying $5.46 a watt, so they better perform twice as good as our panels or you're getting screwed. Our 345W light is $1150 shipped, meaning you could have about 3 of them for the price of their single panel, and our units will cover a larger footprint when put together, while consuming close to 900W of power.

Plain and simple though (cause I don't BS), their light will not compete against our own. I have no idea how or why Advanced Nutrients bought them out, but it wasn't the smartest move on their behalf. Their lights use only 460nm, 625nm, and 660nm plus white. Photosynthesis requires 439nm, 469nm, 642nm, and 667nm. So right from the start you can see that they are missing 1 blue, and half of their output (1 blue 1 red) isn't targeted.

Our lights use 440nm, 470nm, 640nm, and 660nm. Our light is "targeted" because each LED is set to deliver the majority of its light directly at the photosynthesis peak where plants convert this light into energy most efficiently. So the 439 peak is hit by our 440nm LED, the 469nm peak is hit by our 470nm LED, the 642nm peak is hit by our 640nm LED, etc...

Their 460nm blue doesn't even touch 440nm, and since LED's have a very narrow output, it emits very little light at the 469nm photosynthesis peak. Their 625nm red also doesn't hit 642nm, rendering it EXTREMELY inefficient in regards to conversion from electrical to plant energy.

Stealth Grow uses CHEAP LED's, and the most common ones on the market. They don't take time to give you all 4 photosynthesis peaks, nor do they take the time (or money) to target their LED's to the specific nm's where they are absorbed most efficiently. 460nm is cheap and used by everyone, as is 625nm. As you can see, we don't use either of them.

Lastly, they don't have our light intensity, and without this you can't deliver the light efficiently to your plants even if you do have a good spectral output! Plants need light to pass through their leaves for optimal absorption, and their 120 degree lens won't make it through more than the top first couple of leaves. Our lights will penetrate comparable to a HID, since it is equipped with a 4x more intense 60 degree lens.

So if you don't want to waste your money, buy from the company who has already proven LED technology to you: US. Our lights are currently destroying HID in Blaze's side by side, and we actually provide comparison tests against our competitors. It makes no sense to me why anyone would trust some gimmick company who can't even tell you how their 1200W light draws only 580W of power, yet charges you out the ass for an inefficient product...

Are you going to setup a new 1500w grow room at your new location?

Nope. In fact I am selling off one half of the 1500W room displayed. If anyone wants the Aero unit and 6 lights used during this test, please let me know. The package deal for all of it is $2750 shipped.

Thats a good deal. I wish I had the cash. Im having a hard time just saving for a 205w. so no more test grows?

I moved several months ago and was supposed to do some "test grows", but I was testing out a form of TAG (misting) and needless to say it didn't work half as well as advertised. It screwed up my crops for a few months and left me with nothing. I'm moving again in another month, and then again at the end of summer. If things go well with the move, I'll do one demo grow over the summer myself. I NEED THE MEDS! Right now I'm forced to buy them for the first time in about 2 years!

Sucks so bad to go from being able to grow yer meds for about 10 bucks an oz, to buying them for 250 an oz....

Yup, around $250 an ounce when you buy a QP at a time... At least I have quality hookups though for times such as now ;) It sucks not having a garden though. It's been a huge part of my life for the last 5+ years, and not having plants around is a bit lonely. I know all of you can relate how stress relieving and calming it can be spending 10-15 minutes in your grow room every day, and I miss it. Hopefully I'll be growing again soon :)

Agreed, I need to go spend me some time with my girls right now. Just got my lil'ninja down for a nap, so its time for some gardening and a few bowls! Wish you the best of luck gettin up and growin again soon, as I know I most certainly look forward to seein' yer next set up....

look im not a noobie you need to educate about photosynthesis..

Congratulations you put yourself in a category that most don't fall into, one where people don't need educating. This is fine except that I can tell by your responses below that you do need education or you wouldn't be here.


it operates ACROSS the 400-700 spectrum. not 439 exactly and then none at 440... please. dont patronize me.

What operates across the 400-700nm spectrum? PAR? While Chlorophyll may be able to absorb 430nm, it has NOWHERE near the absorption rate of 439nm for Marijuana. In other plants you may find 430nm as an absorption peak, but we're not growing marigolds here. The same is true for 630nm. Even though plants CAN absorb SOME of this light, they absorbs FAR MORE LIGHT at 642nm. A LED at 625nm delivers no light (or miniscule trace amounts) at 642nm, making it VERY INEFFICIENT. Likewise, the region between 500-600nm has such LOW absorption amongst plants, that it shouldn't be used in grow lights at all! So why would you use a 625nm LED when you know it has less than half the absorption of a 640nm LED? According to you it seems that exact outputs don't matter, but when you're a plant scientist like me you find out quickly that they make or break a grow light.

Also, since a lot of you have probably never seen the actual graph of a single LED, I decided to show you one for the 660nm reds we use in our product:

660nm1.jpg


what about the strength of each LED's stealth uses 2W. the pictures of your lights operating look awfuly red. and maybe its just me but i dont see the blue. with a mh/hps bulb i cant actualy see it.. i cant buy somthing thats so red, my strains enjoy the extra blue or a superblue MH, so red isnt doing it for me, i usualy flower everything under MH.

i dont know what u use, sorry theres alot of pages to dig through.
also-

Sorry Digital, but you DON'T know what your plants want. I ran primarily Blue Metal Halides when I ran HID, as they have a better spectrum than a HPS (albeit lower lumens). I KNOW what your plants want, as I developed a light for them over the course of several years. HID lights weren't developed to Grow Plants, they were developed to light streets. Some companies did small adaptations to them to produce better outputs for plants, but even then they're still wasting over half the light they produce. Up until now they've been the best alternative since science hadn't done anything better yet. Our lights are designed to give your plants the PERFECT spectral output the whole way through the process, and if we didn't then our 205W wouldn't be smoking the crap out of a 400W Blue Metal Halide here on these forums! So TRUST THE PROS, not just some random idea that came into your head of what your plants want. Cause sure they may like the MH over the HPS, but they'll grow twice as fast under our LED's.

As far as their "2W" LED, it's nothing other than (2) 1W dies on a single chip. They use a 120 degree lens, and THIS is the ONLY thing that truly determines intensity with LED's. Our 1W LED is still more than 2x as intense as their 2W's because we use a 60 degree lens. So go with the Gimmick if you want, but that's all it is. They also charge you OUT THE ASS for it.


im intrested in giving the LEDs a go after seeing your thread. but instead of 12 units in a semi dome i want to just hang one fixture. again im NOT ATALL concerned with price. only quality. whats your next step, whats in reaserch? any short lasting 4w LED units?

LED's are not HID's, so if you want to grow with them you'll need to learn how to garden with them. This isn't the same old tech in a different package, it's completely new tech. So if you don't want to use it how it's designed, no problem, but you're never going to get the results out of it that you want, and our competitors have already proven that. If you're going to grow with LED's and you want to cover a large area, you need multiple panels. Period.

As far as our research, I don't think I need to divulge it to someone who speaks to me in a sarcastic and disrespectful style: "Short lasting 4W LED's", "please don't patronize me", "I wouldn't buy any of your panels"... Seriously, LOSE THE ATTITUDE UNLESS YOU LIKE GETTING MINE BACK.

just seams like i wouldnt buy any of your panels yet "there just too small" im looking to replace a dual-arc mh/hps combo bulb. and still fillup my large garden.

Well Hippy, it seems as though you should look somewhere else. You DON'T know enough about photosynthesis, you LIKE companies who sell you with gimmicks over science (or maybe it's just cause I'm a woman that you don't believe a word I say), and you DON'T want to use the technology how it was designed. Seems like you might be stuck in HID land for a long time.

Thanks, again, LEDGirl. Having red the first 21 pages, spent eighty hours of the last work week reading up on LED (one of the first made BLUE LED, 198?, is still 'on') and comparing notes on Light absorption rates and Chlorophyl I&II ... and even reading up on builders and vendors of the LEDs, I am, still, convinced that you ( Hydro-Grow) are on the right track. It IS the ###nm and it IS the intensity.
One thing that I havent found, on-line, are the specific ###nms's for Cannabis... So I am taking your word for "...440nm, 470nm, 640nm, and 660nm, ..." are close enough for Cannabis. (and, thats what I am seeing from NASA, MIT etc. =most green things) Its not Ivy, it aint a Marigold.... Not even Apples and Oranges... :)

Anyway for me to be a supplier for our local Med groups?

(Im thinking Advanced bought out Stealth cuz A.N. KNOWS Cannabis and I will bet that Stealth now comes out with ... your ###nm ##s... at three times the cost, but, they have the name... but YOU have the product NOW)

Sorry about all the house-moves. You rock anywayz!

Stay cool, stay safe

thats a nice breakdown.
i like the garden too, looked really good. the LED lights seam to get penetration fairly good too?

i just upgraded to water-cooled lights, and dont have temp flux anymore. but im no where near as effeciant as you. mad props.

DH... you say you want to try LEDs... are any other LED manufacturer's anywhere near as involved or as up front as LEDGirl? Read through LEDGirl's post history, and the grow logs of the other members on the forums that have used these... I just don't see how there's room left for skepticism... and if you know of anything showing any LEDs performing better than LEDGirl's, I'd love to see them, because I'm planning on making a purchase soon.

LEDGirl - Thanks for all the info. :respect:

439nm, 469nm, 642nm, and 667nm are the Chlorophyll absorption points we found for Marijuana. It took a lot of time to find this information, and we've held true to it since the beginning. We're also probably the only company who states that our product was actually developed for marijuana specifically, so it makes NO sense to my why Advanced (who also says the same thing) would buy a company who was not "marijuana-central", as that's their core marketing audience. If they would have been smart, they would have contacted us and teamed up with a company who actually understands this new tech, vs Stealth Grow and their crazy gimmicks. They say that their 2W LED's are more intense than our own, until you learn the FACTS about their 2W's and how they use them. They admit in Maximum Yield Magazine that they do not drive their LED's at the regulated operating current like we do. Instead they run less power through each chip, causing it to produce roughly half the amount of light that it would at normal amperage, and then run two chips to make up for the lack of light output. So in essence, instead of running a single 1W at 20 lumens, the run 2 diodes per LED at roughly 8 lumens each, for a total output that is still less than you would get from a single chip with our company. They have turned down the intensity by half or more on the their (2) diodes per LED, and then paired them both together in order to say that each chip puts out "x" lumens. So the actual brightness (intensity) you get from their 2W chips is more around 8 lumens x 2, not a single output source at 20 lumens like our own. Did we mention they also use a 120 degree lens to spread their less intense light out over a larger area, making it even less intense? Crazy huh?

Stealth Grow is going to have a difficult time copying us though, as our lights are patent pending (as are their own). If they do make an attempt, know that a lawsuit will follow swiftly once the patent is granted. :)

If you want to become a distributor for our lights, feel free to send me a PM or email and we'll get you setup :dance013:
