I'm not quite sure what the goal is, but I started chitting some Garden Leader "Monster" seed yesterday (seed from Ferry-Morse).
I think I get it now (from the old links). I will likely be chitting some Gardener's Delight and Roma later today.
Sort of a separate experiment, but I have one 2021 potted tomato plant that survived outdoors through several freezes, even with some blooms through the cold. I've no idea what variety it is (sold with the label "Foodie Fresh" on the pot; some patio type). Still alive, I moved it inside a few weeks ago; it's bedraggled but growing some nice leads. It is warming a bit here, and it may go back outside later in February. I will post separately (different experiment; probably will call it "It's ALIVE!!"
).
