The grow light seems to keep the plants happy. They've bolted. The cats might prefer the extra fragrance, thick blades of grass, and extra crunchiness. :smirk_cat:

I have everything set up.

Unfortunately, it seems that the grow light got better seeds. The seeds on that side started earlier and also more of them started. You can see this in the next comment.

This is on the 7th day. On the left is the grow light (very reddish), while on the right is the normal light. See here for a post on the color spectrum of the grow light: https://sjchiass.com/category/plants.html

My thinking now is that the test isn't really accurate. If one light shows itself to be clearly better, then I'll consider it the winner; otherwise, it's within the margin of error.

Note: the grow light has less wattage so if it keeps up that's a "slight win" for it.

The soil-free growing medium is about 50/50 peat moss and vermiculite. Turns out peat moss is a bit like a sponge: it soaks up water and doesn't it pass too much. I think this is why you try to spread out vermiculite/perlite in there to break up the peat.

The plants are doing alright without any real soil. I do add a few drops of plant food every watering. I water very rarely.
