Supposed to be +\- 1%
Also does Kelvin conversion, BBR curves, visible and invisible spectrum analysis, cri indexing.
Sphere not included.

haha. A sphere would be the holy grail but wayyyy wayyy outta my budget.

That's what I was about to say, I talked to owner of clw, I'm pretty sure he said they use few green diodes. They work pretty darn good, but small coverage area.

My 900W panel from PLxxxxum LED (not allowed to say their name here, had like 20 green chips in it.
 
The one thing to always remember is that when you build an array all the chips towards the center have the chips next to them that help boost the par. The further you get to the edges the par will drop so it's important to think of this in your design. You sure don't want to go 7 rows of 3 in a 4x4. I would look at a more symmetrical design.

My wife would try to buy a sphere for 275,000,000 mil. I just got a call she just bought new BMW 7 series. I'm not sure what she bought but dealership told me I can stop buy and sign paperwork after work. Thought I was going to stroke. Why does women try to keep up with neighbors

haha. Better you than me I always say. I love it because my neighbors all think I must be broke. I purposely keep that appearance. I have decent vehicles but that's about all they see. That's one problem I have never had. I don't want to even appear to "keep up with the Jones' ". That could get expensive quickly.

I built her a nice house but I can't see spending that much for a car. I have a brand new 12 year old truck(26000 miles), I'm going to keep that 12 more years lol

Same here man. 12 years old and I'll drive it till the wheels fall off.
 
I see this same argument about green light all over the internet. The empirical science just supports common sense. Cannabis has been cultivated by man for over 15,000 years and probably was around in the wild for many times that evolving on its own out in the full sunlight. Do any of you really think that it would evolve to not use such a large part of that natural light spectrum?

Just think about it.

If you dimmed the 3000k's, would you still benefit with only 4 5000ks in veg with the 16 & 23 layout?

Yes. I always run my 5000k's on a slightly bigger driver because they will run a bit cooler than the 3000k anyways. All my 5000k chips can run at 80w per chip and stay plenty cool. With 4 of them in a 4x4 room you can veg with just the four 5000k's if wanted. Myself I always still run my 3000k chips but really low.

4x80w on the 5000k chips can veg at 320 watts all by itself.
