Our Brandywine OTVs grew pretty similar to our other more generic Brandywines, i.e., pretty vigorous for a big tomato. We love them, but thanks to this thread, we might be going to some Suddeth strains this year.
@thepodpiper, we grew Helsing Junction Blues a few years back, and it was absolutely worth it for my daughter and her cousins’ reaction alone. To them, it was something out of a Dr. Suess book.
In terms of lovely (and yummy) cherry tomatoes, I strongly recommend Isis Candy. They finish off with an “X” on the bottom that pictures don’t do justice, especially when there are 50-60 of them on the vine:
Regarding the lights used to raise seedlings… I used a high-power 400W HPS/MH system for years, then switched over to LEDs the last two years. Honestly, the LEDs did as well as the Metal Halide bulb at 1/4 the price, wattage and fan noise. I’m thinking of boosting up to @100W LED hanging light this year to ensure better coverage of our tray, but I don’t know if I’ll ever go back to the bulbs.
