Can you elaborate on that? I have seen the spectrum graphs for this leds and some russian video testing them, and it seems they have a lot of light in the red spectrum zone...and they pick in 630 nm...better than usual cobsSorry for The delay. Definetly do not recomnend clu04h for bloom. It lacks in red spectrum. Blue and red is even and more red is needed to properly finish flowering. So there are lots of cheaper and more efficient options.
Yeah, to much blue w/o g+y to balance. Wouldn't imagine that would do much better then my Hydroponics Hut. Almost the same spectrum.Sorry for The delay. Definetly do not recomnend clu04h for bloom. It lacks in red spectrum. Blue and red is even and more red is needed to properly finish flowering. So there are lots of cheaper and more efficient options.
Lack of of greens and yellows..exact the same thing that happened with red-blue led lamp in the past...these citizen PRB version are only good for vegetative time and short plants...but I think as a suplemental light in flowering...maybe they have a chanceOkay. Fair enough. I should have been more specific. Next to the prb 320w panel, there was a clu04830h7f 320w panel and it did way better in terms of yield and flowering /ripening period and these cobs are way cheaper.
