The plant leaves under the LED lights are visibly more bluegreen with dark stems and more purple underneath. Otherwise they appear the same for size and vigor.
A few LED plants had mottled yellow on some leaves in the third photo.
From now on, the trays will be rotated, mostly under the fluorescent lights, until set outside.
Any observations or comments are welcome. Again, these are 4 ft. white LED shoplights ($25 at Costco), not LED growlights.

Rick, We'd like to hear the end of the story. How did your Costco lit plants grow and produce once they grew up. Also the rest of you who tried the plain white LED shop lights.
