I've spotted at least 5 so far, not quite as big as a ping pong ball yet. I think they're all on the Better Bush plants, I haven't spotted any on the Defiance plants yet, though there are lots of blooms on it. (But it is a slower tomato, though it was transplanted several weeks earlier than the Better Bush.)

Based on some net research, I've started shaking the plants at least once a day, that may have been what it took to shake loose some pollen. 😀

The photo looks strange because the red/blue lights were on.
