That may be true. My intention is to find out. At the least it will be an issue for some without the extra head space. 3500K 80CRI, 3000K 70CRI, 3000K 80 CRI, neck and neck. 2700K 90CRI and 3000K 90CRI, six inches higher at the moment, about 30% more distance from the base.

Longer internode spacing does have it's advantages, and can be advantageous if it allows reducing the veg time so long as it doesn't affect yield figures. Such considerations might make one source better for SOG when headspace isn't a concern, and another source better when growing SCROG when root mass is allowed to fill out more before the flip.

At this point there is still much to learn and final figures may still sway my opinion one way or the other when it comes to the best spectrum for a general purpose source. If the yield figures favor 90CRI I would consider offering a choice, but if the stretchy plants perform similar to the others then I will consider going straight 3000K 80CRI.

I'm just messing with you...........not a high cri fan if it sacrifices ouput, but more info the better Rahz

You stated the Pro-9 puts out 30% more light than a 1200w DE. I'm just curious if that's documented somewhere. A grow doesn't prove how much light a lamp emitts. Nothing you just posted indicates it puts out 30% more light than a 1200w DE. Is that documented somewhere or did you just make it up? Respectfully...

Here you go bro.
The Pro-9 just spanked the Genisis DE In testing.
It's a true DE killer. Pushing high intensity 90+ CRI.
+19% efficiency
+35% lux
+38% YPFD
+42% PPFD

The Pro-9 is the Commercial LED/light to have.

That is truly shitty PPFD for a 1200w double-ended. A single 600w puts out, like.. 1000-1200PPFD? I'd say these stats are doctored or that particular HPS is shit. Not talking shit, I love you, dude, but that's an issue I'm seeing.

Interesting, but you should explain how you came up with the figures. Manufacturer data? Spot measurements? If spot, how many? What space used?

Something's wrong with the equation, particularly factors pertaining to PPFD. A 600w HPS alone puts out 1000-1200 PPFD.

Well, PPFD is space dependent so the numbers by themselves don't mean anything.

The Florida Sun is apparently 89% efficient. Doesn't make any sense.

Thought it typically refers to square meter, though, but I understand. I have used what you're saying to try to demonstrate before, as you've seen.

Yeah, I wonder what the Sun's actual efficiency is, energy consumption to output.

I don't know all the details. Testing is done using super high tech new equipment by an unbiased party. I'm not at liberty to discuss who did the testing but some here may already know. It's all supposed to be on the hush until they're done & ready to make all this info public.
A hint though, it's the same guys running the grow test w/ many different LEDs against each other to determine the best commercial unit.
Oh, sorry guys, I forgot to mention, it's a 1000w DE called a Genisis.
It's 42% more light in the PPFD so if you add the 200w to make it a 1200 DE, it's about what I said w/ the 30% more light put out by the Pro-9 in comparison to a 1200w DE.
When I'm given the green light, I'll post a link to the study's & results for you guys.

Sure they do, both lights use the same space to determine the #'s Rahz.
It sounds like you're looking for any reason to not believe.
Fact of the matter is, the testing is an unbiased study. So, no ones trying to make this stuff up to make Amare shine. It's done for all the lights that are partaken in the growth study using Tomatoes.
I originally came up w/ 30% based on # crunching I did myself w/ the par #'s Victor sent me for the unit.
Now the study verifies my math. Just wanted to share since you asked bud.
Did you guys notice all the IR in the Pro-9? I was surprised to see that it's more than the double ended.

I don't lie homie. Thanks for the love though, feelings are reciprocated.

Like, 1000w puts out 2100PPFD. In a square meter. 1200w, I suspect, should put out more. Especially using two 600w HPS bulbs, because they are the choice for balance between power and efficiency regarding HPS.

This is a phenomenon I can't really explain. I've seen first hand the measurements in a tent of the Maximizer and a Gavita side by side. The Gavita should look better but it doesn't. I'm not implying anything with this just sharing what I've seen.

A bare 1000 watt Phillips on its best day puts out about 2050-2100...... That said BARE is the key here. Reflector loss is as real as Trump being president elect. I don't have to like it but it's true lol. Reflector loss is 20%++++
