No way bro. COBs have an inferior spectrum because they lack UV/IR, remember? I Should've used DE Tech! :wall: Oh well, I guess this will have to do.

It's an honest question man. Why not hold a tape measure up to show everybody just how much they stretched from the first pic? Not trying to be a dick at all, but how is everybody supposed to get a perspective on what you are trying to show without a frame of reference? How much did they grow...

Are you sure they aren't just 'growing'?

I definitely think you are right. I've done a fair bit of research into the Emerson Effect and the photosystems I & II. I based the ratio of light I chose off the Mccree Action Spectrum as opposed to the solar spectrum. This is why I chose a 3:1 Red:FR ratio. I don't care about extra stretch...

@Randomblame I actually liked the ratio of light that I used. The plants responded well to the added Red/FR. Seemed to keep the leaves perky and pumping out the chlorophyll. That being said, if I could chose a spectrum all over again, I would def choose 3000k 90 CRI for flower. I've always...

I ran 660nm and 730nm during lights on and did NOT notice the stretch everybody keeps talking about. The plants seemed to grow normally or even a tiny bit shorter than I'm used to. The 660 : 730 were in 3:1 ratio and only accounted for about 8% of the total light being created. The rest was a...

Proper Nutrition, Proper Light Intensity, Proper Environment = Healthy Plants;)

I agree that HID tech has the potential to offer a fuller spectrum, but HPS spectrum is no better than warm white phosphor LED's and people can grow healthy plants without deficiencies using either technology. So I'm not entirely convinced that lighting alone, will cause deficiencies. It may be...

What exactly do you consider "full spectrum"? And why?

I totally agree. Pretty useless in the growroom haha!

Not arguing practicality. Just commenting on your incorrect statement. Light follows the laws of physics we adhere to (aside from extreme gravity/quantum mechanics). This topic has also been covered in other threads a few times, which would be a more appropriate place for this conversation...

Nope. Sorry. That is incorrect. Please do more research before stating claims as fact. Just google if the inverse square law applies to lasers....

Are these going to be rated at 80 CRI or 90 CRI? @Stephenj37826

Any news on boards coming into stock? @robincnn

Oh gotcha. Sorry I thought you were referring to Meanwell. Yeah I don't know about that other company..

Since 1982. They started out making power supplies for computers. http://www.meanwellusa.com/aboutEvents.aspx?c=9 I feel real comfortable about using Meanwell drivers.
