What a great comparison of lighting. Both results look good but Viparspectra look outstanding with those stems and roots.

Thanks for sharing this, very interesting video!

Nice set-up, i use the same heat mats, for lights i use a hibrid (natural light whit some cheaper leds).
Thank for good info!

It looks like sunburn on the leaves from the more powerful light. You also have two plants in the second scenario sharing the same pot. Back to your video - love that you did this! I think I would still go with the weaker light based on your results.
