Explain The Dawg's grow then, the 90 CRI has slightly less PAR, he shows the measurements on page one, and yet the 90 CRI plants are much bigger and further into flowering then the 80 CRI ones, same nutes, same clones, just different CRI.

CRI is a measurement of how accurately a light source illuminates an object's true colors, the difference between 80 CRI & 90 CRI is basically how "wide" the spectrum is, how much of the visible light spectrum that the LED produces covers, usually the higher the CRI the more Red light is...

If anyone's interested i called up the lovely people at Luminus and asked if they could provide me with the CXM-22 3500K 90 CRI spectrum, they were happy to help and provided me with an SPD file that i converted into a spectrum graph in excel. I've studied this spectrum in comparison to the...

i'm actually more interested in the 90CRI 3500k if possible.. btw do you happen to have a ModuLED Mega 13450-HBG with the connector set for sale maybe not on the site?

yeah thats what i was thinking, go for the stronger one and dim if nessesery.. i also have a 2x2x4, homebox?

The more i read about Luminus the better the chip seems, i'm just pissed they dont provide a spectral graph for 3500k 90cri, or 80cri for that matter..

for a 2x2, 90w kit or 135 kit?

Very interesting, this chart is for 80 CRI i'm assuming, does the placings change with 90CRI? more specifically how is a CXM-22 90CRI compared to a CLU048-1818 90CRI? and how does a CXM-22 stack up against a gen 6 1818?

Holy moly, now i see the difference, 90 CRI looks so much denser in these pictures! man i love good side by side comparison grows! :clap:

i like how it seems that when lighting with QB's there are no shadows anywhere!, look at the plants in the last picture, where are the shadows?

Beautiful setup! what kind of LED strips are you using?

do i gain any efficiency by running 1818's @ 1050 over 1812?

w-why not? :wall:

Any chance we'll see a few 90 CRI 1812's?

i'm aware of digikey, but $40 per cob is a bit on the high side, i'm on a budget and they're literally the most expensive place to buy from.. thanks for the help though!

oh my, thats quite the difference, cant really tell from the pictures besides the height of the plants.. i thought both spaces were smaller then that! cant wait for the finale... i'm trying my hardest to source 1812's but i'm coming up short.... i wish citizens were easier to find..

Incredible.. is it just me or do the 80 CRI nugs look fatter? btw what how much space does each plant have? 2x2? not sure if this was asked or not..

wondering how long until they show up since i have a feeling they're gonna sell out in an instant...

Dont have any QB's myself (yet) but from what i've read you'll probably be good with 4 boards running about 100w each (might be overkill, not sure), you can either get the boards and two HLG240H driver each to power two boards, or you could always just buy two 260w kits for a quick setup..

2700k? i'm running 2x14.5w 2700k osrams on my beefstake tomato, i wonder how low wattage we can go to get fruits with LED bulbs..
