David Lass is presenting a live show about LED lighting for planted tanks at 10:00 am today (Saturday, May 26) on Aqua Botanic Radio. Here's the link:
Aqua Botanic Radio- LED lighting with David Lass 05/26 by Pet Radio Show | Blog Talk Radio
I believe the 10 am is Pacific Time, but I've no idea if this is being broadcast simultaneously in all time zones or individually at 10 am. If interested, check into it.
David Lass is a name I recognize from AFI magazine, but that's all I know about him or the program.
