I aquascaped aquariums for years so I do know a bit about growing just in an underwater environment.
Were you doing it back in the VHO days?
I had an IceCap solid state VHO ballast and that was cutting edge tech back in the day, coupled with Actinic tubes, there wasn't anything I couldn't grow!
I suspect these days everyone is using LEDs and T5's.
Just about the time I got out of the hobby was when the U shaped compact fluorescents were pretty popular.
I miss my reef tank...
Watching that was so much more interesting than TV.
There was always something going on in that tank...
