These are Rosy Finch microdwarf tomatoes that I'm growing indoors (PNW but that can't mattter).
As you can see they have flowers and have had for a couple of weeks but no fruit has set yet. There is a heating mat under the tray and I turned it off today but am wondering if anyone else has grown these or other microdwarf varieties and how fruit set has been for you. I've tapped them a bit to see if that spreads some pollen too. They get 12 hours of light from the grow lights above them.

You need to manually pollinate them. They actually sell devices specifically for this, but an electric toothbrush also works.
I’d suggest a fan and about 6 more hours of light.
Use an electric toothbrush and tickle it. Flowers are self-pollinated (does not require another flower) but need wind or something to vibrate the pollen to drop.
