>Has anyone tried tomatoes from the Dwarf Tomato Project?<
Yes- I believe this project is the one connected to Victory Seeds. They have many different growers and developers of the Dwarfs, and dozens for sale. I tried Dwarf Pink Passion and Dwarf Sweet Scarlet under lights during this winter in the house. The Pink Passion got 3 feet tall and no blossoms, but the Scarlets are doing nicely, blossomed out at 12 to 14 inches high, baby tomatoes starting - they are a mid-size fruit.
But the best dwarf I’ve tried - second year now - is Red Robin - 12 to 14 inch plants, lots of yummy 1 inch cherry tomatoes. They thrived outside during the summer and kept on when brought back in. Now my new ones, January planting, have a great start inside and will be blossoming any day. Of course you have to pollinate gently with a tiny paintbrush when grown inside. Red Robin is in several catalogs and sites - Territorial and Seeds ‘n Such, I know - not too pricey, and every single seed I’ve planted has germinated.
