you may be right i may be wrong..but you are sure insinuating a" giant difference" between 4000k and 2700

i have used 3000 and 5000 for veg flower acouple times

and admit to not being anal but...

..i didn't see much difference at all..[please leave out the hps comparison..its just not helpig this led discussion]

i am guessing there was some other reason that one plant grew so large.......that sounds like an outlier

"Veg under the 4000k light then move to 2700k they explode in growth and size."

that is not a veg/flower test using 4 k and 2.7 k panels..its not relevent to a real test

a real test is one grow using 4k all through..one using 2.7k or whatever

Fair, however these were all the same plant via cloning. I've grown all the way through veg and flower with 2700, 3500,4000 and what ever spectrum the 315s are.

I'll be able to test more when my room is all one style of light and I can move my 4000k to be only veg to show the dramatic difference. I'll have to post photos of the size difference later today. Only the lighting was different so that's why I point at that.

I appreciate it, I did try that a while back with a 90 cri MH and it doesn't scale to 1000W well from what I've seen. Flowers want more red in bloom but the higher cri does help a bit. My results weren't terrible just not as good as going from 4000k 70cri cobs to 2700k hps were from my experience. :peace:

R2K has the 288 with samsung blues apparently.

I do not understand why no companies have made boards like Photon Fantom Designs boards looked like.
I was a huge fan of the wavy board.

Might be because it takes more time to layout the board with them in that fashion than a straight line with a minimal space savings. However I do like how they mount their boards on angled aluminum which gives me an idea. Its also much cheaper to use the LM561C since they are an older component.

The wavy was all straight lines just incorporated red and blue diodes.
Or do you mean so they're not staggered like on this pic?
It's the coolest looking board I've seen so far.

Its the staggering I'm referring to. The color is interesting and may help. Wouldnt mind testing it out more.

I couldn't care less if they're staggered or not. That isn't important at all to me. I just don't get why you don't see boards with reds and blues in larger numbers like you do on that wavy more often.
It could easily be replicated still without off setting the diodes like they are.

I'll be honest, after checking out that design for a second now, I bet that spectrum would be fuckin wonderful for flower.
The graph is probably reeeeeeeally niiiice.
