Who knows. If it doesn't work whatever. Regardless I'm going need another spot to grow soon if I'm really going to do 2 600W's or 2 1000W's HPS. Woof.

And here we go. Pics with the LED off. Girls are startin to look purty. I was playing with them a little last night, I think they like me. Oh and I wish it wasn't so damn hot here. AC is going to be mandatory soon. Bummer dood. But these plants are growing fast now. Guess I'm just going to let them overgrow in the closet then take several clones of all of them, then flower all the plants worthy of flowering.

I like that someone is doing an LED grow. I know you get a lot of slack about it but if no one tries new things how will we know if they will work and how much they will work. With advances in LED lighting who knows this might be the next big thing. Keep up the good work and will be watching this and wish you the best.

Thanks bro. It was a little bit of investment; like the damn thing costs 2x as much as 600W HPS, but I'm hopping it works. My closet is nuts right now with an overgrow. At least this does an out of control veg and seems to penetrate below the canopy; crap open the closet and it hits the entire room.
I just started to train back the 2 largest plants since they were growing into a new canopy level and I want to stall at the current height. I'll take a pic later. If the yield is horrible or something, it's not very difficult to through a HPS in their.

Plants are getting big. Clones are entering teen phase. I setup my grow tent, started flowering of the adult plants. 300W LED fixture in the flowering room. I'd want another 300W led fixture, for flowering; once I can afford it, it's happening. Ironically the 120W led in the veg room seems to be doing great in the entire 2x5 space?
LED's seem to be amazing for veg. I want to get another 120W led or similar for the veg room. But maybe that is overkill? This stuff is really weird. LED's seem to have pretty amazing results for such low power consumption in comparison to MH and HPS thus far. I'll be continuing the LED testing, even though I am so tempted to run a HPS in the flowering room.
My setup reminds me of my old 1000W HPS/MH system on a light mover. But, light movers at least from my experience don't really do anything. The light of a HPS or MH 1000W easily penetrates a 5x5 area, unless you have massive deep bushes, and in that case I don't think you pruned your plants correctly.

I hope you do end up flowering in an all LED arrangement. We need more empirical data on the flowering capability of these LED's. In my experience, which is limited, the LED's definitely work; but their high up-front investment in conjunction with a perceived reduction in flowering efficiency is what is holding these back. Still waiting to find a source for 720nm+ diodes, as I think that their availability could help tilt the scales in LED's favor.
Here is a diagram of the custom 300w 1w/diode array I had built last year.
I had originally intended to design a light that I would bring to the retail market as a proprietary design. However, while this LED array will grow a plant to be certain, I am not yet convinced that it is capable of doing so better than an HPS light source. Frankly, I will not bring a product such as this to market unless I am certain that it can compare to and in several respects exceed the efficiency of an HPS source.
As one who has jumped into the realm of LED options, I am thankful for your thread fungi, and look forward to witnessing the progress with your chosen LED arrays.

Yah I feel yah. I bit the bullet and picked up some HPS lights. In the tent they are like 20 times brighter then the LED fixture. Still going to use the LED, but sorry it was either buy another LED fixture; which I almost wish I did, or buy some HPS lights. Going be pretty hard to test it now; but I know led's work awesome for veg at least.
Seems like the trade off for power use vs. yield vs. cost is almost dead even. But not. It still seems to favor the HPS unfortunately. I looked into building a led light and that isn't any cheaper then the lights you buy commercially unfortunately or you can get off somebody.
Also what concerns me is all the LED fixtures say they are good for 50,000 hours then they start to degrade. Which is directly comparable to a hps or mh ballast; after 6 years I'm sure it won't perform as good as a new one; and bulbs only last 19,000 hours.

i think it would be kewl to have some leds on like a christmas light strain but have them spaced every .5 inch or every inch and just wrap them in the under growth of the plant... it would be christmas year round..

I am wishing you the best and I hope it works out for you. I would love for you to prove it is possible. With my budget I will only be able to get HPS for now, but with advances in the LED field it can only get better and the prices will go down as it does with all new tech.

If you consider $800-900 for 2 600 HPS, with nice hoods, bulbs and ballasts vs $1,600 for 2 600W LED's, the price isn't that far off if you keep the lights for 10 years. But like I've read and seen, led's work great for small grows. But if you do what I'm doing; not sure it is going to work.

Cool grow. I've been interested in LEDS for a while. A buddy of mine that has a few UFO LED fixtures and a 400w HPS light, and he has great results.
I haven't ventured indoors yet, but if I did I think I want some LED's in there.

Just purchased another 400W LED fixture from http://www.customspectrum.com/
Seems like I was wrong, they both are 400W led fixtures, which pull 4 amps at 120V. I know because I bought this http://www.amazon.com/P3-International-P4400-Electricity-Monitor/dp/B00009MDBU/ref=sr_1_1?ie=UTF8&s=hi&qid=1281073578&sr=8-1
and I have a line that runs the LED + a 600W ballast and it is pulling precisely 1000W and 10 amps, and the 600W only obviously pulls 600W + 6 amps.
So these folks led's fixtures ain't no joke man. The new one is a 12 band spectrum for veg.
Oh and check out this eBay auction
http://cgi.ebay.com/420-w-3w-BEST-LED-GROW-LIGHT-300-400-600-1000-mh-hps-/280545013418?pt=LH_DefaultDomain_0
for one of their lights. Hell of a deal if you want a pretty darn good led light for veg or to supplement in flowering.

Well I screwed up. The HID's seem to be no better then the LED for flowering. Plus the stupid Hid lights are so damn hot. They add a good 20-30 F when the LED only adds 10 F. I have the two 600W HPS aircooled and it is still 85 degrees + in my tent. With the LED is it below 80. Even with ambient temps at 60 degrees.
Well I guess I should have trusted myself. LED > HID. Great now I have some worthless HPS equipment to sell.

i'm sure the leds r cooler.. but just get some more air flow.. if ur hoods r air cooled add one more can fan to suck air outta the top of the room and a fan blowing in fresh cool air from another room.. but hey do what ya wanna do.. those leds r temping....i wanna try some

Well it got colder here. Room temps inside are more like 70 F. Which I find more ideal. Once I secure the funding, I plan to run all LED's for flowering and put the HID's temporarily in a closet to prove that yield with LED's is the same or superior to HID.

I can already tell you for a fact that keeping the light that far away is gonna end badly, soon as flowering starts they are gonna stretch like a mofo and fall over in a week because of it..
One of the main things about LED is the low heat factor which allows you to get them really close for maximum intensity, which is what the plant wants to grow the best it can.
Which when growing 100% indica strains isn't exactly a bad thing dood. Please don't question my ability to grow weed.
