CXB spectrum vs output

I am super interested to hear/see your results Bobby. If I had all those COBs it would be tempting to just blend them all over my panels as evenly as possible. That wouldn't really tell us which spectrum is performing better though.

i have 8 ea 3000 3500 and 4000k 3590s on way from cutter and they will be run side by side in a single tent so i hope to get some insight on spectra/yield

the 4000K DB is close to 20% brighter than the 3000K CB so we'll see if spectrum or intensity is king

Please correct me if I'm wrong, but the whole debate of spectrum vs output seemed to be about comparing a low output, but desirable flowering spectrum(I.e. 3000k) with one of higher output, but thought of as less desirable for flowering (I.e. 5700k). When you use 4000k, which some believe works well for flowering already, that 20% difference in output should show yield gains over the 3000k CB. That is my prediction anyway. The disparity in red might affect quality, though.

yes and hence im testing. why would i run a flowering test with 5700k when we already know it will fall short

I think i'm getting the 72v as I got some HLG-185-700b not in use I could run 4 cob per @ 50%
& want to try the 4000K

Just to see what would happen? I think with red monos 5700k COB would kick ass. And by the way I wasn't suggesting that you run that test. Just stating my prediction for the result of your actual test and why I thought so.

Apache had red and high k whites years ago and so did a51. Damn right that combo works. However, since whites became more and more efficient sufficient reds and deeper reds are now present in the Vero and Cree cobs.

I still run two a51 panels that are red/white with results that easily outdo most all I've tried. Cobs do better yet but these panels kill almost anything else out there. Not even thinking about updating them. These have Cree chips!

I have the rw series and they are still hps killers imo. Apparently there's finally going to be an upgrade for them as well.
