Cuban oregano is a possibility. I got a cutting from a customer, and then she lost hers over the winter and got a cutting from me. I like Mexican oregano in the jar better than my greek, the greek has almost no flavor, but the bees like the blooms and it's a ground cover. I keep it confined, it's not too bad about taking over.
I had too much light with my transparent panels, temps over 120 in summer. I have plenty of flourescent lights from aquariums.
4 hives at the moment, 2 mature in large boxes, 2 started from purchased queens this summer in nucleus hives. Bees on my oregano a few years ago. those pics aren't very good. Back in the day I had to reduce image size to save hard drive space I think
