Best LED for 3x3 flowering

[NoFucks2Give]

UV and infared will help with growth

Just because it's on the internet does not mean it is true. These are stress induced methodologies and should only be used if you know precisely what you are doing. It's nto the same as adding blue and red to white. UV and IR are not photosynthetic wavelengths, they signal defensive phytochrome responses and secondary metabolites.

Based on this image...it seems to be pure madness to consider anything besides 5000k, but clearly that is not the popular opinion.

It would be madness to make any decision based on that image. You really need to take a breath and learn a little more before jumping to adverse conclusions. This stuff is more complicated than you already imagine.



Apparently the madness has subsided:

It does look like Vero offers a 2700k cob. Perhaps Timber is able to offer it. But yeah, assuming I get 4 cobs total, what would be the best arrangement for blooming?

CRI is an rating for how natural the light is or how it matches sunlight. Most LEDs are deficient in red when compared to sunlight. The higher CRI of 90 will provide more red. The Vero 1750K 97 CRI is a very nice spectrum. It has less intensity becasue it takes more energy and florescent quantum efficiency is lower when producing deep red from a phosphor pumped LED.

That is exactly why I post these things, so people can tell me if it makes sense or not.

 

[SchweeDubz]

I'm not sure what the CRI is on the 1750k for Vero. I want to say the others are 80 but I'd have to confirm. So is the lower intensity worth it? Or am I better off going with 2700k or 3000k, with slightly less red but more overall intensity?

M'y friend use 3000k because he's doing both veg an flo under them and he have Véro29, me i use 3500k for the same.setup because im using cxb 3590

 

[madininagyal]

Another things To considèr , the g/w under cob, all m'y friend and me have noticed yo Simply smash out biggest yields in term of g/w with an very big increase of the terps for those growing under hid and better yield for me using my old mars hydro panel (stay away from those purple led) ,

 

[Rahz]

Ok, well assuming it's been tested and not a myth, (not that I actually think it is, but data always helps convince) would 3k be considered ideal? There is an option for 1750k for the Vero setup. Would 2 and 2 make the most sense? I have heard 2700k come up as well but I don't see it as an option on Timber.

My testing indicated no notable morphological differences 3000/90 -vs- 2700K/90 and had 3000K yielding slightly better. Results are still inconclusive. 3000K has more blue (12% -vs- 8%) and is slightly more efficient. It's possible 2700K is a better spectrum per radiant watt but in practice there's no evidence to suggest it's better than 3000K. Same goes for 1750, possibly being a better spectrum for flowering but also loosing out on efficiency. Where the sweet spot is nobody can really say with certainty at this point. 3500 and 4000K are also contenders. Good news is, it's difficult to make a bad choice as the yield difference is likely small.

You can rack your brain about it all day, but in the end, but as Rahz said, there isn't much of a notable difference in 2700k and 3000k. I personally mixed my bloom light between 2700 and 3000, but I'd choose 3000k if I wanted only one temp.

 

[SchweeDubz]

Mixing would be nice. Timber doesn't offer 2700k but they do offer 1750k. I would consider mixing but I am hesitant just in terms of the layout. With 4 cobs, one in each corner, it seems smarter to just stay consistent and have uniform lighting throughout the tent. I am currently inquiring about adding a 5th cob to the center using a 1750k.

I agree it probably doesn't matter a ton, there doesn't seem to be any direct evidence to suggest that color temp plays a major role (at least between 2700k vs 3000k vs 3500k, and some pages seem to suggest up to 4000k for ideal growth), but I would rather overthink it than under think it and end up with another Mars unit.

Pretty sure if you talk to someone over at Timber they can make that happen but be prepared to be more than satisfied!

 

[SchweeDubz]

I've been talking with Dan from Timber and our conversation is pretty much as long as this thread, hah.

They are working on old ideas that a specific colour is all you need to grow plants. It does, but not great. You have to consider plants have evolved for millions of years under the sun, so many parts of the spectrum are important to so many aspects of plant growth.
They use cheap diodes ran hard which means they don't last long
For the same reason they are very inefficient so your getting less light per watt.

Its the lack of light that makes airy buds.
Kind, Blackdog and most of the high priced ones use almost the same stuff as the cheap LEDs but they come up with some sales pitch and slap a crazy price on them.
The only place you will see the grows using these types of light is youtube, where some soulless creature is paid to push the product.
If they were anywhere near as good as suggested every weed forum would be full of grow journals showing the results. But there not, except for that forum which is sponsored by Mars!

False. Kind and blackdog are BADASS leds... you dont see tons of grows using them, because they are insanely expensive - NOT because they dont work. Once you learn about diy lights or qb's, its hard to justify spending 2grand for a light. I would WAAAY rather spend half the money, on a ~750 watt diy light, using qb's with few cobs mixed in

Have you taken a look at rapid led? Their 3 COB, 240 watt vero 29 D series, diy kit is only $220, AND you get a 10% discount on 1st time purchases... thats about as cheap as Ive seen for a quality diy COB setup. They also have the cree 3590's for $300 if youre after efficiency. Timber is noticeably more expensive...

They have Built and DIY routes

Has the #s and Facts a skeptic like yourself might get behind.

Dude, are you a salsman? Im seriously asking. Because youre recommending the priciest, "pay for bells and whistles you dont need" lights. ChilLED is WAAAY overpriced... "oh, but they operate submersed in water!" SO WHAT?! You growing seaweed or cannabis? My advice - spend $185 on a diy Hlg qb288 that can pump out ~159watts, and steer clear of the 90watt ChilLED that theyre selling for a $300.
note- they SAY that theyre 100watt lamps - but that is just what it pulls from the wall, including the driver. Its only giving u 90watts for $300...YIKES!
You could just about build a 2 board qb288 light, that puts out up to ~320 watts for the same price...
HLG all day long

Well, I am going to use my Mars II for vegging, it seems fine enough, at least for now. I expect it to crap out eventually and maybe I'll replace it with a veg specific light then. But it creates good temps, and I don't see stretching. Very small light burn here and there. Airy nugs tho!

I don't expect the CMH being hard to change heh, it's more of that $80 cost twice a year that adds up.

Minmaxing is essentially what I want to do here. I would like to figure out the best setup for my 3x3 space (currently with 5 plants). Like I said, the Mars II isn't delivering dense enough buds so with this purchase of a new light, I want to make sure I am getting the ideal grow. The Vero 400w setup on timber is probably seeming the most appealing right now, but my main concern with that is if I need to supplement UV lighting, or any other spectrum issues. The G8 600 still seems appealing as well as it covers UV etc, but its $900 and still pulls 50w less than the Vero would.

@madininagyal I will try and do a price comparison with the Vero kit on rapidled and let you know if a. they have all the parts and b. the cost difference. Thanks!

If youre after a vero 29 set up, Im telling you... rapid led will blow the doors off of timbers pricing. Plus, they will work with you, & advise you of your diy options, if youre looking for a custom build. VERY inexpensive to part your light together this way. Dont pay $750+ for a light until you have checked out HLG - if you want COB leds instead if quantum boards, go to rapidled.com - they have 12 COB cree kits that'll cover a 4x4 for $900 if you want max efficiency... or get the 12COB veron29 lamp for ~$700. That will MURDER anything you can get from Timber & ChilLED at that price point. Just email them & ask them to help you build... whatever u want. Theyll send u invoices & are endlessly patient with quetions. Theyre my #1 choice for COBs, & 2nd choice overall behind HLG.

That is why they are included VERY sparingly in led diode lamps... be careful if youre diy'ing your own "diode style" led lamp... u need little to no uv/ir

 

[SchweeDubz]

Lol I appreciate the advice but I already went with the 400w Vero29 setup from Timber. Perhaps a bit pricier than what I could have gotten elsewhere but it's all setup and I'm glad I went with this over the Platinum LED XML2 or w/e it is.

The dude Dan was very helpful though and answered probably 50 of my questions before I made a purchase.

RapidLed sell kits, not assembled fixtures. For $750 you get cobs, heatsinks, 600w of drivers and assorted hardware but this does not include the frame.
Timber sells a 600w kit with the same gear that comes assembled in a nice frame ready to plug n' play for $899.

So how exactly does RapidLed 'blow the doors off of timbers pricing'? LOL@Murdering someone else's prices.

Once you add the cost of the frame to that $750 it's up to $939. If you add the reflectors like Timber includes in the pricing it bumps it well over $1000.

Dan at Timber offers every bit equal support on the products as RapidLed does. Don't get me wrong I order from RapidLed and like the online shop but you're talking about blowing doors off and murdering someone else's prices....and in reality it turns out they are more expensive for the same wattage light fixture. The only slight advantage you get from the more expensive RapidLed light is twice the cobs running half as hard but for some they might even prefer the 6 cob setup and it's slightly higher hanging height. Plently of folks will undoubtedly prefer having the light be plug n' play which is a downside for the RapidLed light and should add to the cost because you either have to pay someone to put it together or take the time to do it yourself...which some people don't have.

 

[CobKits]

Or do brands like Platinum LED not use efficient components?

this

if you want a premade there are few top shelf choices
hlg/timber/tasty/plc

all of these are better than platinum/mars/perfect sun/optic/etc

not to say that lights that incorporate reds and blues are bad
amare and california lightworks are some good ones that use top-quality components
