LEDGirl, I feel that you have done a really good job of explaining yourself and answering all the questions people have had. I'm no pro but just a noob at this. I have done alot of research on LED systems and have learned more from you in the past 3 days than I have in the last 6 months. I am highly anticipating the results of your friend's and Ed's testing. I really wish I could also join your testing. I've personally emailed you and you have always responded very quickly, so I appreciate that. I was the one who asked to compare a 600hps vs another led/cfl system vs your system in my grow tent, but my funds (like most) is super tight right now. So I really can't wait for your find.
Keep up the good work.

all wicked plants, but......why didnt you turn off the LED's for the pics? rotfl........kinda cool effect, but i like seeing the shades of green :)
i'll stick with my HID lights, anyday.
fact is, LED lighting systems are like.....only obtainable online where i am at, so.......yeah. that answers that for me. i'd give 'em a try if i could.

The 54 w were spread out over a 5 x 9 area, and if you read my notes the hids were not on all of the time - they were really the supplemental lighting but whatever - I'm not here to argue but it drives me crazy when people only look at the facts that support their argument and ignore the others.

Wow, that's just ridiculous, spreading 54W of LED over a 5' x 9' area? I see two rows of 3 bars in that space. You just solidified it to everyone though that you're full of shit, as there is NO WAY IN HELL, that 54W of low power LED (ESPECIALLY hung that high) can produce anything close to 2 oz's, ESPECIALLY WHEN YOU USE IT OVER 45 SQUARE FEET! You SERIOUSLY think any of us will believe that your results are attributed to less than 1.5W per square foot of EXTREMELY LOW intensity LED light? Again, you're ONLY trying to JUSTIFY your extremely expensive purchase. Go blow your smoke somewhere else. Maybe if you were using 54W of high power LED in a 1' x 1' space, at 6" above your plants, you could produce your 2 oz's...

People like you give this new tech a bad name by spreading so much bull shit. I can't believe you'd actually lead people to believe that 2 pounds came from 54W of LED. You should be ashamed.

This recession has hurt a lot of Americans. I completely understand the lack of funds thing, or my veg garden would already be full of LED's :(

Anyhow, Ed should do a great job at showing the true responsiveness of LED to HPS. He'll show you how many watts you need, to create X amount of yield, in a Y sized area, through his results. That way people won't be so afraid to try the technology, and spend the extra money to get something that will last them for 10 years without servicing. You've gotta see that it works, before you can justify the costs ;)

The nice thing about LED though for the pockets, is the monthly savings on electric. I'm personally saving $160 a month right now, because I switched from 4,000W HID + A/C + Fans, to 1512W LED. My growth rate is faster, plants are healthier, and I save almost $2k a year now on electric :)

Because when I turn off the lights, people like to tell me that the plants were actually grown under HID, and that we simply hung up the LED's to take the photo. Next time I go, I'll try and get some good pictures with a flash, and the lights out. If it wasn't for all the haters, and people who like to voice their negatives, instead of just picking a different thread to post on, I'd have likely done this already, as it makes the plants much easier to see.

Dillweed, I can't believe you (of all people) bought the load of bullshit he was spewing about his 54W of low intensity, low power LED's, spread out of 45 square feet, and his claims that they supposedly made 2 lbs of bud.

Of all the people on this forum like yourself who are questioning LED's, you're the one now who's not screaming bull shit? You just amazed the hell out of me.

Ed Rosenthal is using 3ea-318W led's ( that's close to 1000W of LED power) and going to compare it to 1ea-1000W HPS ?

Is that right?

Oh, I don't believe him either but it still doesn't mean that you aren't a cherry picker, my dear. ;)

Yes, Ed is going to use a 1000W HPS over one grow space, and over the other will be 954W of LED. The point of the test is to establish some sort of an equivalency, by using close to the same wattage. We expect the LED to outperform by quite a bit.

Since you have compared the 318W Led's to being comparable to a 1000W HPS; the test should be just that, a 318W led grow and a 1000W HPS !
Report the bud quality and yield of both grows.
It is implied that the same plants and number of plants would be used in both of the grows.

This one every one will understand. What say you?

I took some pictures just now of three of my plants under LED, with the lights out. This way you can see the color of the plants, the THC content, etc... a lot more easily. The first picture plant is going through week 3 right now, with the two other pictures in their second week (a few days apart). The first photo is Afghani X Brazilian Skunk, the second two are of Ice Princess: White Widow x Cinderella 99. The oldest plant right now is in week 4, but she's short and hard to take a picture of. Anyhow, enjoy the pix.

The test wasn't decided by me. It is ED's test, and he told me what he wanted to do, so I gave him what he needed. Don't think I didn't suggest 3 of our 126W units against a 1000W, but HE is the one who wanted to do the watt to watt comparison, and I think a lot of people will thank him for it. If he yields 3x or 4x with LED, vs his HPS, then it's pretty easy to equate at that point how powerful each unit is on it's own.

To my understanding, each room is of equal size, holding an equal number of plants, and all will be clones from the same mother to keep things as fair as possible. The only difference will be the lighting and the yield.

Three 318 watt LED lights cost $3,300 to buy, emits 36,000 lumens and weighs a combined 120 pounds.

One 1000 watt HPS light costs $300 to buy, emits 150,000 lumens and weighs less than 10 pounds besides a remote ballast.

I'm just sayin'! :shock:

First off, how many of you use CHEAP-ASS equipment to grow your plants? A TOP quality, Hortilux 1000W puts out 145,000, but you aren't using one if you have a $300 setup. Also, a $300 setup means your ballast weighs 40 pounds. A $300 1000W Setup looks like this:




That's $175 for the ballast, $70 for the Generic GE Bulb, and $41 for the cheap reflector, plus tax.

Sure, plenty of people grow with this kind of a setup, but it's like comparing a red/blue/white LED, to my 6 band light. You're not talking apples to apples, when you give me a LOW-BALL 1000W setup. A professional runs a higher quality ballast, higher quality bulb, and a vented hood. These setups retail between $450-$650, not to mention the fan/ducting you still need to purchase at an extra $200 to run the thing...

So what's your issue, the lumen rating? Considering that a 1000W HPS doesn't make anywhere near 1000W of usable light for the plant, who cares about 145,000 lumens? It's not an efficient way of rating HID lights for plants, as they emit a TON of light that plants don't use, including the HPS's peak output in the yellow spectrum. So 36,000 lumens of precision-tailored, photosynthesis specific light, or 145,000 of everything plants don't use, and the little bit that they do? No offense, but at some point you're going to have to acknowledge that you're not giving your plants 145,000 lumens of photosynthetic light with a HPS. You're also going to have to acknowledge, that while HID is the market standard right now for growing, that it is not an efficient light source when you compare how many watts it uses, to how many are available for plant growth.

Hey nice thread here.

I understand a comparison on a few different levels will be taking place soon, as even with yourself, am I right? I am very interested to see this. It looks like the ladies are coming along nicely. I am also eager to see the chop/weight pics of those.

Best growing.

I'm excited to see the results too. People are so set in their ways - but LED is going to get there eventually. I'm not going to make the change until I'm confident the bugs are worked out and the price comes down - but I'm definitely not going to be one of these block heads who refuses to accept any suggestion that LED's will replace HID's one day. I'm sure the first guy who grew plants indoors under lights had to deal with skepticism...and the first hydroponic pioneers..."it will NEVER work! You HAVE to grow outdoors...in DIRT!" and "Hey, what are you....a bucket salesman?"

Hahahahaha! Change is good. Can't wait!!!

Hey Ledgirl I understand the point you're trying to make, however the terminology you need to be using in order to make that point is PPFD not lumens. PPFD stands for Photosynthetic Photon Flux Density and describes the density of photosynthetic friendly light. Just figured I'd help you out :)

Project Fuoro - That graph that you display as your avatar is TOTALLY distorted....do you know that ?

LEDGirl- Do you have a PAR meter? Can you give the reading with the 316W LED at 12" and the reading for the 1000W HPS at 24" ?

That would be a good thing !
