To say they are exactly what I hoped for is an understatement. LED grow trays, Kennedich Seed Tray Kits, are performing beyond my expectations. No leggy seedling growth is occurring beneath the intense lights. Hooray! These, and other similar trays, are still available for purchase online. In combination with seedling heat mats, even seeds three years old are sprouting in days.
MINDING MY P'S WITH Q 
Oh dear…It is my understanding that LED isn’t good for us. Wonder how it effects the plants.?

I have it in the basement, and eventually, they are headed outdoors. I am getting a really early start this year. Last year I grew some Larkspur indoors under LED lights. It was the only time they thrived indoors for me. Almost all the seeds came up and became stocky in shape rather than leggy.
