I noticed that with Flat Nano+ plants are growing faster. I switched to no co2 and just potassium and micro frets. I think that due to natural flow of light with ColorFull LED, plants are living better and ember tetra hatched eggs successfully, Daylight circle provides the environment with circadian rhythm seems to affect everything turning into something better.

 

I can say for sure that Flat Nano+ is one of the best lights I have purchased and I can't wait the buy more ONF lights for my other scapes
