Given the jungle that's growing, using a brush or the little vibrator that Aerogarden sold on every bloom would be very tedious, I'm not sure I can even reach them all! I ran across a video where the idea of shaking the plants was suggested, and that seems to have worked.
Tomatoes are supposed to be self-pollinating, as each flower has both a male and female part, but they probably rely on wind at least as much as on pollinators to move the pollen around. I've got a fan going on the plants during the day but I think shaking them may be more effective, so that's now part of my daily routine. I've been needing to add between a gallon and a gallon and a half of water every day for the past month or two. So I shake them several times a day now, including just before and after I check the water level. Then I go do some exercises on the home gym equipment that's also downstairs. 🙂
