Anyone using Blue Life SPS 20k bulbs?

[Obi-dad]

I want to try 20k bulbs, and was going to try XMs. Has anyone used the 20k Blue Life SPS bulbs?

I am running the 14k blue life sps bulbs if that helps.

I am going a different bulb next time because of slow growth if that helps.

We use the 14K at home and love them.

My husband has used the 20K at the prop. facility that he works at but feels that the 14K have a better spectrum.
