I've been vegging under my vero's even starting seeds. Pepper Seeds, Pea seeds and Cannabis seeds. I've had the best seedling growth ever. Better then under my 400watt HPS.
My light is probably 3.5 feet above the plants. My pea's are going crazy 3 weeks old and 15-16 inches tall.
There's definitely some calcium uptake differences I had some issues for the first couple weeks starting to get things back to normal now.

Mr. Head.
I am interested in knowing what you did to balance out the nutrients for your grow under led

I agree with this, for those of us trying to learn about DIY LED lighting it would help immensely if the knowledgeable people making recommendations could be more specific in regards to part numbers. Also abbreviations are a nightmare when trying to learn things off of DIY forums, but that's probably never going to change.

organics and time.
I was having uptake issues due to it being so much colder in here during the day when the A/C kicks in. It's taken a bit to adjust and get used to how little heat these lights put off.

I'm sorry it's taken me so long to reply. You should be able to create a thread, but I'm not really sure on the limits to new users. I'd suggest you try to create a thread because you do have some very specific concerns that I'm not qualified to help with and you should get a wider audience. I don't think your climate would necessarily dictate which you choose, it's more along the lines of how much your electricity cost and whether it's worth it to you to pay a bit of a premium to be able to run at say 50% efficient vs 40% efficient.
Hi here,
i need advice plz , i just bought 3 vero 29 4000k, ( will add in the future surely some cree cxb3590 and others vero 29 to replace my 2 hps 600W )
but i would like to have the "real" led's power , mean , take advantage from monochromatic leds to complete spectrum.
( cob are replacement HPS if i understood correctly ) so it has some advantage compared to hps , but its not the big led's advantage
I already have 2 hans panel 65w , it works good , no doubt on this , but i know , he didn't mounted "best" led on it, to make it less expensive .
So which monochromatic leds are the best actually ? and in which nm i should take it ? ( it will be for veg/bloom period )
I heard good about the SSL80 Olson in red , i saw many type of royal blue too ( some at 445nm , others at 441nm ect ... )
And knowing that vero cob will be power at 80W each , is what i need 80W of single led ?
( i supposed , its non sense to put 3 single led by example , surrounded one cob , it would change nothing ? am i 'm wrong ? )
ps : i know there is some panel like this , like Osram zelion , but 1k$ , woooo,
i think i can get for less expensive , something nearly from zelion or other stuff like this huh
other thing : do it is possible , to see one day, cob but in single color ( like royal blue cob deepred cob ect ..
thx for help

So I am assuming this is where I ask for help on what to buy to build my own LED light, so I will give it a shot.
First I have read several threads where SupraSPL has provided incredible information.
So here is what I have found so far:
1.Heat sinks- heatsinkUSA
2.Cooling fans- several places including Amazon
3.drivers-ebay or digikey
4.driver wire-18 gauge stranded alarm wire- ebay and other places.
5..25" crimp slide connectors-elecdirect
6.Cree COB led- digikey
7.blue and red led- Steves LEDs
All of this info I got from SupraSPL post on another forum, don't know if I am allowed to link it so I won't, he probably has it posted on this forum too and I just missed it.
So I just finished a build out in my garage, the room is 2 1/2 ft. W x 6 ft. L x 8 ft. H.
I will have a/c going to the room(Texas) and already have phresh carbon filter and hyper fan for the exhaust.
I'm only looking to grow 1 or 2 plants at a time for my own consumption.
So what would anyone advise for my setup.
basically how many cree cobs(which ones specifically) and red and blue leds(specifically), and how many drivers(specifically). If I use the 25 watt per square foot formula would I be looking at 12 cree's, seems like alot...you tell me.
Thank you for any advice.
P.S. I’m currently growing in a tent with the mars hydro reflector series 3 x 96 and while it is working, it is clearly not enough light to produce results like i am seeing on this forum...works fine for clones and vegging though.

Don't complicate it for yourself. Either 3000/3500/4000K is all you need.
You might be able to get some higher bins Cree COBs from Kingbrite even probably cheaper. Good source for MW drivers is Jameco Electronics. Fans/wire/connectors I'm sure can be sourced locally or from Jameco too.
I'd say that 12xCXB3070 with 3xMW HLG-185H-C1400 would be a great choice for your space with PPFD about 900-950 µmol/s/m^2.

The vero 29 4000k is a pretty balanced spectrum - I don't think you'd need to add any mono LEDs to the mix, just run the Veros on their own. The only thing that might give a boost are a few deep reds (660nm), but I don't really think it's necessary. Also, if I remember correctly you're running the Veros fairly hard at 2.1 amps. Even if you had some room on your driver for some 3 watt mono's, you won't find a red mono that can handle 2.1 amps, so you'd need a separate driver for the monos at probably 500 or 700ma.Hi here,

Try a couple runs with only the Veros - I think you'll be happy with the results. I would say that cobs are a big improvement to HPS - not just a replacement. With white cobs you get a better spectrum, better efficiency, less heat from IR, and less light loss from bouncing around inside a reflector (a problem with HPS).
Thx man , you right ,i'll be waiting to see if i'll upgrade with mono led.
hmm question about driver.
Now i have 3 arctic fan cooler , they run 12V@0.5A each
i bought an universal transformer 12V@0.5A but I would like to connect the 3 fan on this transfo.
You know I cut cables , I put all red cable from fan together , same for black cable, that I connect to the 12V transfo
Well this is what I would have liked to do, but I'm confused now cuz I read, with 3 fan 0.5A each one, on one transfo , I needed 1.5A in total ???
or the transfo can deliver 0.6A max.
So .... wrong advice from someone ,so I should have taken an transfo 12V@1.5A, and I bought this transfo for nothing ( well at worst it will serve for 1 fan at least ) , or do I can make as I told (cut cable ect ... ) ??

I don't have any of those Arctic coolers, but .5A seems pretty high for a CPU fan. Is it this cooler you're using? http://www.arctic.ac/us_en/alpine-11-plus.html
That one is showing .16 amps at 12v on the website spec page. You probably don't need to run them at 12v though - I think Supra found that 5 to 6 volts was all that was needed to keep most cobs around 50c or less.
hahaha , i'm must be too stoned , ive got this one http://www.arctic.ac/eu_en/alpine-64-plus.html ,
I had believed , i read 0.5A but its 0.25A.
Now on the switching power supply its write :
PRI : 100-240V-60/50hz 160mA
SEC : 3/4.5/5/6/7.5/9/12V----___ 600mA
i already dont know if i can connect 3 artic on this power supply.
I'm afraid cause , 3 fan on this should need 0.75A so ?Maybe its only at 12V ,
if i run them at 7V , maybe they 'll need less amperage , maybe it'll match the 0.6A of the power supply...
I'm such a dick in this domain , shame on me....
wooo this is like chinese language for lol , but will be cool for others , thanx for this man

I should begin this with I'm not very experienced with SMD, surface mount soldering or any micro type soldering. Through-hole soldering is the only thing I have worked with and have a lot of experience with it.
I created an account here because I know cash croppers have a bit more invested in their LED setups than the average user. I'm surprised at the results everyone is getting with "white" light. Looks nice! A local store only carries LED lights with deep red and blue (maybe a white mixed in on some) (and a massive pile of used ballasts they bought back from LED converts!). It's also interesting to see one of their new models has semi opaque white diffusers which must take away 25% of the light. I use the term "must" but it's just speculation. The plants grown under the LED's are impressive, they have done in-store side by side comparisons with HPS, T5HO, even LED vs LED. The plants just look funny without white light present to reflect the green.
I have a 3x5 tent (for a 2x4 setup with room around the sides), but don't have the space to set it up. Also have a 600W digital sodium ballast with a conversion bulb used to get tomato starts going at the end of last winter and have used it for lettuce and basil. 600W HPS is nice as far as efficiency goes but it is just a little large for my needs. 2'x4' is more realistic for tomato starts but I still don't have the room for it year round.
I'm a DIY type person and have shop space and tools, have done electronics work. In my surplus pile I have 3 very large black anodized heatsinks but they are only 1' long, very deep fins (5"?) in a pattern which should work either for convection or a small fan could be placed nearby. The aluminum is not very thick in any section, it could be an issue. Other heatsink materials I can think of is aluminum bar, then milling a couple of fins into the top or extruded aluminum - less time spent machining is good.
So if I want a blue / red combo, any suggestions as far as Digikey, etc for parts? A link to a modern setup that works? Say if I did want to flower something, maybe add a strip of red LED's?
I've tried the cheapo LED's which screw into a standard socket and have 5 LED's with a reflector and lens, 3 red, 2 blue. Put them above a small citrus plant I brought in for the winter and all of the leaves dropped within 48 hours! They were at least 3' above the top of the plant. There could have been another factor other than the light - as in maybe it got too cold before I brought the plant indoors.
Not looking to spend a lot of money since I'm not doing a cash crop.
Right now I'm rooting some basil cuttings under a ~23W 6000K CFL and a blue LED, both in cheap sockets, type often used to incubate eggs and for shop light use.
Thanks for the tips ! Again, very impressed with the photo's I've seen!

If I'm reading Guod's file correctly it looks like at 12v their fan was pulling 150ma (.15 amps), which is more typical of a small CPU fan and in line with the other spec sheet I looked at. They also used some resistors to test the fan at different voltages, to test for noise and power used. Dime - do you have a multimeter that you could use to test the fan current?wooo this is like chinese language for lol , but will be cool for others , thanx for this man
Not sure about your heatsinks, but you could always use some thermal paste and kapton tape to test it. If the sink gets too hot to put your hand on after running it for a while then it's probably not going to work for you. If it does work then mount the cob more permanently.
I think most of Digikey's mono LEDs are sold unmounted, meaning you'd need some bare stars and the capability to reflow solder the LEDs to the stars. It's a bit trickier than using a regular soldering iron, but I've seen online tutorials on how to do it (never tried it though). Their are a few online shops that sell quality bin mono LEDs premounted on stars - Steve's LED is one of them. You can also check with aquarium lighting websites. Not sure what part of the world you are in and what's available to you. Else just stick with white COBs, I think plants prefer the fuller spectrum of a white cob over monos anyways, and you can get the COBs in smaller sizes for smaller applications (see Cree CXB25xx series, Vero 18s and 10s,etc)
EDIT - OOPs I was thinking disengaged's post was a continuation of dimebagor's post (no avatars and similar names combined with my inept reading abilities). Not sure what I typed was relevant to disengaged.

Hey all. I've been doing quite a bit of reading over the past few months and while I've certainly formed some opinions, I figured it was time to just start asking questions at the risk of sounding stupid rather than dredging through thousands more pages of responses.
So! I'm looking for LED light recommendations (obviously).
I'm planning a DWC SCROG grow using isolated buckets (not recirculating). I've done some outdoor and some ad-hoc indoor grows before, but this is my first "serious" attempt at an indoor setup. Here's what I've got going:
Already own:
4x4 grow tent
Humidity/temp monitor
Electronic PH & PPM testers
Fan controller
Light timer
4 DIY DWC buckets roughly based on this guide (http://forum.grasscity.com/do-yourself/121335-lets-build-bubble-bucket-step-step.html ... essentially 5gal buckets with large airstones, drainage valves, fill valves, and water-level meters)
Air pumps, check valves, etc.
2 x 6" oscillating clip fans
GH Trio (but planning on following the Lucas Formula)
Strain: Reserva Privada Skywalker OG (feminized, photoperiod)
I'm set to purchase the 6" VenTech (440CFM) fan with carbon filter as well, unless someone talks me out of it.
I don't have a set budget for lights, but I'd prefer to not go too far over $500 if at all possible (but I'm absolutely willing to go higher than that if that's the best option). Also, I'm not really up to DIY an LED light at this point.
My initial plan was to just do 2 x DWC buckets, but I'm willing to do 4 (they're already built) if that's a better option.
So, can anyone recommend me a light or set of lights for this setup?
And, while we're at it, is it reasonable to SCROG 4 x DWC buckets in a 4x4 tent or should I just stick with 2 for now?
Thanks, and let me know if there's any other information I should provide!

Looking for an LED. New space made is 30in x 30in. Pretty much going to use it to start plants in for veg a few weeks then flower. Prob 3 plants total 5g pots. Currently have a 400w hps laying around to throw in there but too big and to much heat for my area. Want to go something that give off cooler temps. Want something that'll put out enough light for just 3 plants. Something to replace a 400w hps or something a little lower if it'll run cooler and be easier on my electric bill. Very interested in trying out the LEDs while I have my other space going. I'm sure I'll get answers as I should make my own etc. I'm looking for something I can just buy. Nothing too expensive but nothing cheap and off name. Willing to spend money if it's going to do the job just not be ridiculously over priced.
