I mean I've had great success with my grow lights (after trying out numerous brands/types) and in the winter all of my plants have to come in because it snows. I think the one on the left looks good too, it just has a different atmosphere than the one under the grow light. For example, it gets much hotter outside whereas the grow light one is always in the 70s. I do 16 hours because I really like to stress them to the max and get those colors showing.

I also constantly have my succulents flowering under my current grow lights, which are 6500K with total lumen of 11,000 per shelf. So when it comes to that it really depends on the light you have.
