new lights at Area 51

Ditto what? You never used any of their lights so how do you know what works better? Like I said before, you need to grow something before you get your discounted light, they don't give em to non growers. Just sayin

DITTO for the fact I was going to purchase this light....If I wanted a handout I would go straight to the source... not via here.... you seems upset about it though.. wanna talk about it?

and still no pics of your grows... how come junior?

MOVING ON!


I will say after talking openly about it with a few people I kind of made myself feel better about the new light...

There is a method to the madness, and I don't see any reason why this new panel would not outperform the SGS (more efficient whites, more red)

For my peace of mind I break it down as they are running the CWs to consolidate "space" on the panel so they can add more red, without being inefficient, and keep their 15-20% blue.

After running all my whites, personally I think NW is your "all around..." if you have a "direction" that lets you use more efficient emitters, wouldnt you? the xpe's are already like, top 3 right Supe? I get what you are saying about the warmer color temps hyroot- root growth kicks in with a little more red... but I think id still go CW+R (erhum. AT's 4:1) to keep stacking my nodes how I want- and still get that perk of root growth, or even all 6200+ for mums to just stack-stack-stack.

As a "GENERAL" statement- more blue is better- especially veg- but yes, you can "accent" the spectrum with peaks that provide specific activity... The more and more I talk about it the more and more Im thinking about getting one. Damn white cases.........

That panel look a little like how I built mine. 2/1 white and red. I'd think a neutral would be ideal but I'm also sure a company does much more spectrum testing than me so the the cool white could very well be the right choice.

from the looks of it the new spectrum they have should make the largest flowers of their choices. Kinda surprised they didn't put a few deep reds in there...reinforces my idea of trying 630nm out in place of 660nm to see if they have similar growth effects.

We used to use cool whites + 630 reds because they were the only somewhat efficient whites available. The reason I don't use them for flowering now is because their peak is in the green/yellow range and missing out on the red/deep red similar to HPS. They contribute lots of blue, but blue LEDs are a much more efficient source of blue (55%).

So nowadays there are 3000Ks that are 38% efficient and reasonably cheap (XML2 T4) or even cheaper 3000K COBs at 42.5%. They have lots of red (more than HPS) and some deep red. If you want to add deep blue and deep red you can, but they great on their own from what I can see so far.

Anyway I agree with Scotch the XPE 630nm is one of the best weed growing LEDs although keep in mind these are not advertised as P3 bin. Because of the efficiency, A51 is one of the best commercial lamps available IMO. Any chance we can get confirmation of the bins?

EH is pretty open about the bin #s, should be up soon on the site. Yeah the xp-e 630nm is an awesome emitter, still would like to see some 640/660nm added down the line on his products, BUT he's stubborn about it

Ya there are a few really good deep reds available. Even if there is some argument whether deep red is better or worse than red, deep red does work about the same as red. So we might as well spread the spectrum as much as possible as long as we are using efficient emitters to do it.

Im hating Area 51 shipping at the moment, ordered about a month ago, shipped 10 days ago, ive yet to recieve them, if i knew shipping was goin too take this long, i would of gladly paid for quality shipping instead of the cheapest usps shipping option.

Supra, I have the highest respect for your input, BUT, I respectfully disagree.

580-630 provides ~ 95% of the PS mj needs. 660 MAY have a place (Indicas), but, in limited % of the overall spectrum. I grow sats, and have personal experience that it does little to nothing for them, OR, I have low quality 660s, which is a possibility, but this includes BOTH hot5 and leds

@ petflora 580 -625 is the wave lengths that suppress melatonin. So I respectfully disagree

Hmmmm.

Here is a link to CMH, which is the new hot choice replacing hps. Note the strong 580-625 range, which most hps have as well, and people been growin some awesome meds with both.

IMHO, scientific data, like PAR peaks in R/B are WAY overblown AND the middle ground is very integral, sort of a catalyst. Yes, you could have too much catalyst, but you can also have too little

It is a very short list when it comes to high efficiency red LEDs. The Cree XPE red is 40% efficient. The only deep reds that can keep up with that are Luxeon ES (38%) and OslonSSL hyper red (39%). Top bins in all cases of course. If you are using anything other than those I would not vouch for them.

Those deep reds do most of the work in my Red/White/Blue modules. I can vouch that they grow just as much bud as 630nm reds alone and probably more because you are spreading the spectrum.

Well, looking at your recent pics under the 3000K cob, it doesn't seem like you are missing anything bud wise, but, some 660 can't hurt, and like you say will help spread the overall red spectrum

Ya we can do without much 660 and still get good results. HPS nugs are a good example and the 3000K as well. We used to build RWB lamps without 660 because there were no high efficiency 660s in those days and results were very good.
