Black Magic Tomato Seeds

I am new to growing and started them late...so far the plants look healthy and I'll post pics later with some fruit🤘

I started these indoors the first week of March because I live in Wisconsin and have a shorter growing season. I used sterilized (oven = 250 deg, bake for 2 hours in aluminum pans with lid) organic germinating mix and watered in the trays from the bottom up. Placed trays on heating pads and indoor LED growing lights (16hrs on). 8 out of 10 seeds germinated, 7 survived to planting in late May. I gave the extra plants away to friends and planted 1 plant in full sun with compost and some egg shells mixed into the dirt. Watered every 3rd day if no rain; fertilized (organic fish) and sprinkled some bath salts (about 1 Tbsp) around the base of the plant every 2-3 weeks. This grew to be a big plant. My plant was threaded through a 6' rope trellis, and the plant grew long enough to go over the top and back down to the ground, so runner vines were about 12-14 feet long. No problems with diseases or insects, using standard organic methods of control (neem oil), plus I aggressively removed dead leaves & stems on a weekly basis.
The taste was truly exceptional; it's hard going back to "regular" tomatoes after tasting these!! The harvest was generous. The tomatoes varied in size from 2 - 8 oz each, dark burgundy coloration with dark green/black on top. I harvested more than enough tomatoes to fill a 5-gal bucket over the course of the season. It made fantastic spaghetti sauce, paste, and stewed tomatoes. I even gave some to friends, and eventually there was a waiting list for more "of those dark red ones". I am definitely growing these as an annual favorite, and next time I'm keeping more than 1 plant!
