These are the Scarlet Sweet and Neat from HPS Seeds
I spent a couple of hours yesterday moving all the tomato seedling peat pellets into coffee cups. The soil is Veggie Hero Potting Mix from American Soil and Stone in Richmond, California.
From the catalog:
An ultra-compact, dwarf variety that is bred to thrive on
windowsills, decks and in patio containers. Strongly branched plants produce
masses of sweet fruits over a long season for continuous harvests. Petite, 1
inch round fruits weigh less than an ounce, with a memorable flavor that
sparkles with sweetness. Vines will reach 12 to 14 inches if staked.
