anyone know if these expensive, new fangled lights actually work....does any do LED only grows....i am curious if they are worth the cost....thanks...CP

Just one or two links to LED grows, if you use the search at the top of page you will find more.
Oh and welcome to the site and good luck.

There can be only one. it's the Wife.

There's actually a section called "lighting". The short answer is that if you want results don't use L.E.D.s.

Have you looked around and seen what people are doing with LEDs?
Or have you bothered to ask anyone using LEDs for an honest opinion of how they do with them?

OK, I'm going to tell you anyway.
Results with LEDs usually mean slightly less dense bud and just slightly less wgt, but more trichome production and increase in potency. Blind taste testers have always been able to tell the LED stuff was better. (sighted testers have not been used yet)
Another plus with the LEDs, no need to run duct work and use (in my case) a 400+cfm fan to cool them (more electric use). The LED setup raises bloom room temps a couple of degrees only above ambient. The other big plus, with less radiant heat generated your medium won't dry out as fast, instead of watering ervery other day the LED plants go a week. But that's not all....because less moisture is cooked off from the pots the amount of salt build up is reduce tremendously.

Here's a couple of pics of some LEDs. How about 2 TI problooms for a total power consumtion of 660watts vs 1150watts total for a 1kw HPS.

See, a side by side comparison of LED and HPS. I've actually used both.
(I also use T5s, love to overdrive them)

"But, when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government, and to provide new guards for their future security." -Deceleration of Independence

To add to Mac's list of LED benefits, with the reduction of ambient temperature and decrease loss of moisture there is less "smell" during the flowering stages with no decrease in the taste and smell in the finished dried bud.

So far my high intensity LED grow is producing buds of similar size and density and extremely low stretch. My theory is to use the same number of watts per square ft as HPS and see the results and so far so good. The up front cost is quite high right now, but as the market matures the prices will come to the point where HID is now.

I don't even want to think of how much I paid for my first 2 - 1K HPS/MH setup back in the 80's. I had friends who were fellow growers that were laughing at my concept of growing indoors with "light bulbs".

The world keeps changing my friend and I, as always, want to go "furthur".

MP

Hey MP,

Yup, good point about the smell.

Like I said above, just being honest with my results. But in my other set-up I have a hybred LED/T5 light using 8- 2' T5VHO= 320watts and almost 400watts of Red LEDs plus a few "other spectrum" stuff. It beats the hell out of a 1,000watt HPS. Bigger buds stronger herb, I don't know why people would not want to step up to the future.

The pics above are from a grow I'm partered with, using pro-mix since he's a "long time (10yrs)grower" but just a dirt farmer in my eyes. Some of the things I've been doing is trying to show him there's a better way to do things. Not just lights either, hard to break notions.

You know what I mean?

Yo Head Shake,

I keep kicking myself that I only recently started taking pics. But even since I started taking them, I still forget to document the build. I did it once (tutorial) for the franken fogger set up I built, and posted at fogponics,dot,com. Those pics I'm moving over to an album at IC, but it will be awhile.

Here's a pic or two of those same pair of TIs on a frame with 4- 4' T5 VHO. this is the current set-up, experimenters are never finished.
The spacing of the T5s needs to change, inner ones shade the edge of LED lights. It was built to hold 2- Procyon 100s, but decided to sell those (money got tight suddenly).

Sorry I have no pics of the ballast itself. To get them to VHO levels (4'=85w/tube, 2'=40w a tube) I use a ballast made by IceCap, Inc. and is a model 660, capable of driving T12s,T8s,T5s and even those square base Power Compacts floros, like TT105s. I bought a package that included end caps, standoffs and wiring harness, abt $300. And that brings up cost. It's probably cheaper to just double the amount of T5 HOs. ie:To do a 4'x4' grow tray I'd use 8- 4' T5 VHO via IceCap ballast or 2-4' T5 8bulb fixtures. 680w VHO or 864w HO and both set ups give you about 80,000 lumens. 180+watts saved, it should pay for itself.

A few pics of hybred and a few of my cloner light, 4- 4'T5 HO (54w/ea) plus 1-4' super actinic white in the middle. Designed to go over 2-120 EZ-cloners, but just using one, and side for small plants and seedlings. OH, and one happy hybred growing girl!

Yep, ahem..
I am a dirt farmer in more than one way.
At least I've been think'n about DWC, maybe in the future.

MP

Hey MP,

There's nothing wrong with being a dirt farmer, that's how I started.
Age of ten me and my older brother were sent to my aunt and uncles' farm in SC because my uncle got called up from Naval Reserves. Tended tobacco, veggie row crops and my favorite, hemp. Couple of years later I was helping and learning from the hispanic workers tend patches of "wildwood weed" in the hedge rows between fields. Did not even know it was mj till a few years later. LOL

At least you stepped up to the future with your lighting!

Oldmac,
Don’t want to interfere with this thread, but I could use your opinion on an HID/LED combo grow. Here’s a link HID & LED

Hey Horse intrude away..........

.....not my thread either

sorry for the hybred hyjack, just wanted to show off that LEDs don't work. lol

I'm still waiting to see a big bush, grown with LEDs ... all I ever see is small plants, healthy, but small ... I know the LED will be the way to go, someday, but I still haven't seen it ... I'm as anxious as anybody, especially when electrical rates skyrocket

Hi Image Reaper,

I know I have heard you say that before. I was just telling someone on another thread the object behind my combining LEDs that really don't have much penertration with T5 VHO that don't have good penetration either (compared to HPS) is to grow single cola plants. I think a nice height is 14"-18" tall. I even think using HPS to grow small is more efficent.
Here comes my inflamatory statement:

It is my opinon that the most efficent way to grow mj indoors under artifical light is to grow small single cola plants, as many as your light or space permits.

Here's my thinking: I'm only interested in the bud of the plant. I want it to be as big and nice as it can be; I'm not interested in a big robust stalk many mutiple branches and all the leaf matter that goes to it.....I'm only going to throw it away! Why should I spend my time (it takes longer to grow big) and my money (electric ain't cheap) to grow a bunch of plant material I'm not going to use? Hope you see my point.

Now don't get me wrong, I love a big beautiful mj plant, outdoors. You should see some of our NL crosses in the field, 7-9' tall and at least 12' in diameter.
Just don't have the space or wattage to replicate mother nature inside,even tho they say it's not nice to fool mother nature....I think I can.

yup, I see your point, the LED could probably work excellent in a SOG-type garden ... I'm waiting for the LED that will allow me to grow my conventional plant (5-6 feet, multi-branched) just my thing, I like to see them grow out ... the ultimate LEDs are coming, it's only a matter of time ... I would imagine the prices are starting to come down, too ... rumors have it, some huge utility increases are headed our way, we may all wind up with LEDs, soon

Hey IR,

Your wait my not be all that long, the commerical use of LED lighting is accelerating at a remakable pace. That is where gains are being made, in light output and power....we just have to wait longer for a trickle down to the niche market of horticulture.

But we will probably wind up first adopting "parking lot" light technology, much as we did with HPS.

Thanks for understanding my indoor grow philosphy.

I'm with ya, since I fulltime in an RV now, (12-volt lifestyle, ya know) ... I am real anxious for LED to be right for me ... I can visualize growing a big girl in my shower stall ... I only have a single 135-watt solar panel now, but would happily add more, to power an LED grow lamp someday

Wheres the best place to buy LED's?

My first indoor grow with LED:
Procyon100/4 23w cfl
DWC/Aeroponics
Bagseeds
3x3x7 closet

Temp in the closet never really got above 80 this summer. And now with cooler temps rolling in it's been a steady 70 in the closet and all I have is a 6" pc fan in the ceiling for exhaust. There are many LED grow logs on here including mine. And as stated above, virtually no smell either. Gotta love it.

This was grown under leds.

Brought her outside for a true color photo prior to harvest.

IMO, LEDs are well worth the cost for personal medical grows.
Watt for Watt, they are much better than HPS.
On identical 2' clones, the 150W Led light grew larger, tighter buds, than her sister grown in Hawaiian sunlight.
(With the help of a little CO2.)

Could those long slender leaves be of the “Homie” pheno?

HMR

Good guess.

She would be one of Homie's aunts.
And Daddy was a fatty of the polecat persuasion.

I'll take some snaps of the present led girls and the new outdoor ganja kennel tomorrow.

tonight.

These are some images of plants that my friend is growing under LED. Up until the day the pictures were taken, she was running 4, 126W units for a total of 504W. The day the pictures were taken she added in a 5th 126W, so now she has 630W LED. Anyhow, the plants are at 5 weeks into bloom, and the buds are extremely dense. Not all LED grow lights produce the same results, and I haven't seen any on the web that were as big as hers, so enjoy the pix:

How about provide grow results, want me to stop doing that? Kind of hard to not do one as they go hand in hand. How can I post a picture of plants in bud under LED, without saying who makes the LED? Seriously dude, smoke a joint and chill out.
