By the way, here's some pictures of plants at 5 weeks into bloom using 504W (4 x 126W units) over a 2' x 4' aero tray. They are being grown by a customer and personal friend.

Do you work for the company that sells these lights?

Yes I do. I also stated that a few posts ago

Do you have a husband named Rory. I say this because because of your Real name from the other forum and I think I might know you.

Nope, I'm a lesbian. I have a wife though

Ha Ha, OK, They are from Medford Oregon but I had to ask, been trying to get in touch with them for a few years now with no luck.

The commercial link pasted all over your pictures, and your repeated posting of material linking to that site, is in violation of our TOU and you should consider editing them. Please re-read the TOU you agreed to upon registering if you have any confusion. Thank you.

L.e.d are junk

I am new to the forum, and extremely interested in growing with LEDs. I have never cultivated MJ, but plan to grow other things. I am pretty good with electronics and understanding basic electrical theory, and plan to build my own light panel using reliable parts from the net.

My question is, how much is enough?? Personally, for a small home operation, i think a 600w HPS is overkill and a waste of electricity since most of the energy is converted into both unusable spectrum of light and heat.

Leds sound like the right idea given plants only need certain spectrums of light to grow and be healthy.

How much LED power do you really need for a 3-5 plant setup??

I'm using 300 watts of LED light for a grow about that size through flowering. This is my second grow using them and they do work well.
Just make that the individual emmiteers are strong enough. 3 and 5 watts each are preferable.

M.P.

thanks for link to the ledgrowlights. I posted this very question on another topic I started but nobody replied as of yet. I'm guessing these can get expensive or maybee a bit difficult for first timers but there seems to be very good for air flow and heat. Can someone tell me about how many would be needed in a stealth cabinet or closet size grow box?

To me, a stealth cab and a closet are two way different sizes. I would say:

Using good parts and efficient drivers, 50 watts of LEDs will match 100 watts of CFL, fluoro, or HID.

Costs about $2/watt for the LEDs plus $1/watt for the drivers.

So, for $180 you can build a 60 watt LED light that'll match 120 watts of something else. (A 90-watt UFO will NOT replace a 400w.HPS. That's a sales pitch. 200 watts of high-end emitters and drivers, though....no problem.)

Not really cost-effective (yet) unless:

a) heat is a big problem
b) electricity's real expensive, or
c) maximum stealth (no electrical or thermal footprint) is critical.

I'm probably gonna put together a DIY tutorial if anybody's interested in building their own light. Let me know, Hermie.

I guess thats true, when I think stealth cabinet I think roughly half of closet (at least height wize) or maybee one or two rubbermaid boxes stacked ontop of the other, like : SUPER Stealth Rubbermaid # 2 (new strain)

I'm guessing from what you said price wise its more efficient for other methods. I'm not sure of a cabinet (size I mentioned) or closet would have major heat problems but I have yet to build.

I'm thinking one advantage over the other methods though is that the led lifespan should be more? or am I wrong?

forgive ignorance what do you mean by driver (led)? I've normally seen only leds in computer/electronic components, not hardwired in sequence.

I would definitely like to see how its setup, so a diy would be great. no pressure or anything but I'm curious already.

Oh, leds will last several years in any decent design. What we're hoping is the current production will be obsolete long before that time. Lotsa companies making streetlights, residential lighting, car lights, etc. Technology will trickle down. Still, for some, leds make sense now, for any of the above three reasons.

I guess when I talk about a driver, it's like a Mean-Well brand unit. They have an A/C plug on one end, and two wires, + and -, on the other. Very simple and neat. You wire that directly to the leds --nothing else is required.

It's a power supply, but it's also got current regulation built in. You can dial the voltage up and down, and limit the current to dim the leds. You can run your leds exactly as hard as you want.

With highpowered leds you can power each color with its own individual driver and have total control of the spectrum.

The "current controlling electronics" part itself can also be referred to as a driver, too, but you have to add a wall-wart or some other kind of power to them. That's pretty simple, too. Real cheap, but not real efficient.

I have a grow going on using a 600 watt Full Spectrum LED panel. Check out the Video on youtube.. Please subscribe!

heres some leds

I'f ur not going to spend more then 500bucks on an led systems its not worth it IMO. I've seen the difference first hand in light output and the panels that work on the HID scale are around $1000. Keep in mind the 2watt bulbs they use for these panels cost about 20bucks each. My hyrdo guy over at the store is putting together a panel to sell that incorporates 3watt leds, its going to be a 600watt HID equivalent and is going to be about 1300 bucks. They sell some really good systems over there but he's trying to get more bang out the same size panel. They have some grows set up in the shop, and the UFO light was ok but not much for flowering and the bigger systems were so intense u couldnt even look at the light with out doing damage to ur eyes. I'm gonna wait for the price to come down on the systems worth buying before i make the decision to change.

"Keep in mind the 2watt bulbs they use for these panels cost about 20bucks each"

That is incorrect by an order of magnitude.

3 Watt "stars" are around $5 ea.
High quality 5 Watt mounted emitters are only 8 or 9 bucks.
15 Watt emitters can be had for $26.

Dunno where you get your info, but I'll be happy to sell you 2 Watt "bulbs" for 18 bucks each.
Such a deal!

Still, you are right about waiting for decent commercial lights at a reasonable price.
Won't be much longer.

Aloha,
Weezard

Well it was directly out of my hydro guys mouth who's building them. I asked why they cost so much and his answer was the leds. I tried to find some places that sell the LED's 2w or 3w but cant so i only have to go on what he said.

Now that i'm looking more into it, im finding LEDs that cost a buckets load that have high lumen output. NOT YOUR STANDARD LED that cost 2 bucks.

But still they can be had cheaper.

Reading this thread has been extremely tedious and to be honest I skipped a good deal of it. Typical forum fodder...

I've been researching this quite a bit. Seems that LED tech is still being proven depending on who posts but HID is a known quantity that delivers consistent results.

Furthermore, experienced naysayers demand even greater performance than HID before they'll accept LED's.

For myself the heat/fire-risk issue from HID is a deterrent and LED lights would solve my awkward attempts at using CFL's effectively.

My conclusion is that higher wattage panel such as 300+ should work adequately for veg and flower?

Long time grower seeks LED information. if anyone wants to see an honest pictorial, as well as an hps comparison, read the last couple posts: or if you're reading this in the future-read the first page...and look for me.

504W Test with LED Grow Lights by Hydro-Grow - Grasscity.com Forums LEDGirl...maybe you can answer the question that you were asked in this now defunct thread? It would definitely add credibility to your story.Nice pics tho-that purple sure draws em in...dont it?

Kinda funny how she bagged ass after she posted her advertisement.Shrewd...I'll give her that.

Following Ledgirl's lead, I figured it was time to introduce MY led grow light.You guys were wrong about the wavelengths.It's green yal...these are my patented "Kermit Green" .25 watt diodes.The unit is 15 watts- but you need 75 of them to cover a 4x4 grow area.I think I need to work on the name tho-
