Citizen Horticultural COB CLU04H - Plant RB

@bles Still waiting the results!

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.

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 cobs
What they are lacking ,only in the PRB version are greens and yellows..which are fundamental to reach the intracanopy leaves. In fact..they have a very good red spectrum zone compared to other cobs.. Their only problem is that they are less efficient than other cobs ... But..the spectrum.. the PW version had a beautiful spectrum to grow with...also they have more far red..
.I have been using the Pw version and they work great in flowering

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.
Betcha it's great for veg.

Okay. 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.

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 chance

They work very nice in veg indeed. Just a couple weeks ago I finished ebb&flood veg and cloning area powered by PRBs. Very happy with the results. I'm running 4 cobs at 80 w each for 4x4 area.
