Other plants that follow 18/6, 12/12?

What other plants veg at 18/6 but flower at 12/12? I'm growing dwarf tomatoes right now but I want something thats I think the word is phototropic?

Actually all plants and algae are phototrophs. I think the word you're looking for is Annual. Any Annual plant follows the 18/6 12/12 cycle. They only live for a season and then produce seeds and die. So you'll need to find out if the plants you want to grow are perennials or annuals. Good luck.

Tomatoes can carry the mosaic virus, which can transfer to your ladies.

I think he means photoperiodism or something to that effect. Poinsettias is all I can think of
