Have you tried the Growing under Light forum?

I'll have a look, thanks.

It's only because a client asked a question about whether changing their lighting type would affect the plants.

I said "it might" and that was it.

I have a CFL bulb for 8 houseplants. It was to be an interim measure while I figured out a more comprehensive lighting system.
But it actually is working well. I move things around, I keep it on 16-18 hours a day.
I have some succulents, sage, rosemary, among others. even the sage is doing surprisingly well.
the bulb is a "ecobulb daylight" by Feit electric, 200 w, recommended by someone on this group. Thank you to that person. :)
