Hey Dok,

That`s the longest couple of days I`ve ever seen, dude. Let`s go already! - RT

Agreed. This kind of behaviour is certainly not going to convince anyone to buy one of these lights.

It cannot be a coincidence that these threads always make it all the way up to just before harvest and then suddenly stop. Very fishy if you ask me!

There is a clear trend here. Is there anyone that can provide a link to a LED grow that produces 3 to 4oz of bud per plant? That's a decent HPS grow, some are better some are worse.

There are no successful grows on the net. The only people getting success are the LED sellers, not the users.

There is a guy who has success with tomatoes and peppers and that was with $1200 lamps, but none with MJ that would bring a paradigm shift.

Sorry for the downer, just trying to keep it real.

3 months for you and your editor to get this printed.:roll:
Please, this thread has more views then that mag will sell copies.
The OP created this thread on multiple forums all over the grower community.
Just shameful advertising of an inferior product, if you ask me.

Very nice LED grow, respect

However running some quick numbers in my head I don't think thats very efficient. The initial price is simply too much, I guess electricity wise LEDs can be a little better than HPS, but the cost is just too much for power efficiency to matter. And if it is heat issues - a cooltube type of reflector solves it, i run my 400W HPS through one and it is safe to put much closer to the plants compared to those 300W LED modules, as little as 10 cm / 4 inches

I definitely wouldn't throw those away if someone gave them to me, I'd be rather happy, but I will never buy them at that price.

Like all cool new things, LEDs have a LONG WAY TO GO, before becoming a viable option.

Wanted to say nice setup and good looking progress for a L.E.D. grow. Two quick questions for you. What nutrients did you decide to go with? Also I see in your two veg. chambers you have a standard UFO and a all blue UFO but the flower chamber looks like it has the 300W or 120W unit not a 90W. What wattage are you working with in your flower chamber?

I wanted to throw my 2 cents with leds lights.

I've been building led lights for aquariums. These are high powered leds are are nothing like these "grow" lights. Now for aquariums you use blue/white lights. Building one yourself costs around $250-300 in parts.

Using high power leds you mount them on a large heatsink, like a computer, and have fans blowing over them. Without doing this they melt. These look like their just in a plastic case. Someone who actually owns one should take it apart and post pics.

Secondly, leds are like spot lights. You need them a few inches from your plants and then you would really only be hitting the top of the plant.

I'd say these are the equivalent of using cfls, at the 10x the price.

Damn. I've been hunting around now for a while, pokin around at the idea of growing my own, and these LED's sure LOOKED good. Glad I checked. thanks guys.

Alright I just read this entire thread and no one mentioned this one time, we all see he is using soil. What if use DWC/Bubbletronics? Constant o2 vitamins etc... is it possible that LED is meant for hydro maybe? Just what was on my mind after reading 12 pages, Not taking away anything from a amazing grow that was done by this LED crusader :) + rep

i totally agree, i just ordered 4 225w panels of red and blue from ebay for $90 that is 900w of LED so go check that out and im going to do a test run on a DWC and soil to see what the outcome is and how different of a yield is. so ill be making that journal as soon as my lights get here so just look for it =]

I hate to say it, but I'm about to burst your bubble here. Those panels aren't 225W each, they are 225 x0.06W LEDs, with a total output of 13.5W each panel. So really, for your $90, you got a grand total of 54W of output, nowhere even close to the 900W that you stated. This is not to say that they can't work, but they are not going to grow more than one plant effectively, and more than likely only as supplemental lighting. If you want a good comparison test, do a side-by-side grow between the LED setup and either a 75W or 100W HPS. EYE Lighting has a 100W HPS bulb with a 1900K color temperature for pretty cheap, and ballast kits usually run in the realm of $40 online. Anything much larger than these sizes, and you're pretty much guaranteeing that the HID lighting will do better.

Also, for the vegetative stage, you might consider comparing it directly to a 65W CFL, since this is right around the same wattage as all of your LED panels combined. The HPS would be good for the flowering stage.

Pay attention when I start my grow log around the end of February, beginning of March. I'll be doing a same-wattage (300W) comparison between LED and HID lighting, using fog-ponics as the growing method. There is also another thread on this forum, where the grower has a direct comparison between a 600W LED setup and a 600W HID setup, side by side. Check it out, though I will say he is using soil as his growing medium.

To a certain extent, I agree. The majority of the lights that people are buying and using in their grows are of the cheaply built, snake-oil variety. I'm probably going to be purchasing a few that, by the research I've done, *should* be better quality than those. Once I've bought and received them, I will more than likely take them apart and post pictures online describing my finds.

That said, once I determine, for myself, the advantages of LED lighting, I'm planning to build myself a 300W LED "pole" to be used in a V-ScrOG cabinet setup, using high-powered 5W LedEngin chips.

I will disagree on one of your points though. LEDs are only spotlights if they have a narrow beam angle. The vast majority of LEDs used in these grow lights use a 120-degree beam angle, and as such, don't have that one "bright spot" that you are describing. In fact, if you were growing only 1 or 2 plants under a 90W UFO, a narrow beam angle would actually be advantageous, as the light would be more concentrated in a smaller area, and thus would penetrate the canopy more. For a larger grow, a higher-wattage, wider beam angle is advantageous.

Hey guys

I just read this whole thread and wanted to add what im doing.

i purcahsed(at a great price) on ebay 2 LED boards 24 watt each..

i have 6 plants going 2 under led's and 4 under CFL..

SO FAR it's a tie 1 week into this experiment. i will be starting a thread soon..

I am doing this for the average home grower not someone looking for 15+ plants i just like this as a hobby :) so i will keep ppl posted! i ordered more seeds and im going to test LED vs CFl under 100$ total budget!

If you buy an expensive one, post up some pictures of the guts of them. An led pole is a good idea.
