I repotted the taller tomato seedlings. These are the Roma VF II, that I grew from self-saved seeds. Heirloom, grow true from saved seeds. Bush type, determinate growth pattern. Meaty, good flavor for salsa and tomato sauce,
They were a bit leggy, because I didn't get them from the warming mat to the LEDs immediately. So I planted them about and inch deeper. They will grow roots from the sides of the stems, and planting deeper is standard for tomatoes. They perked up again in a couple of hours.
I re-use the plastic pots. These have been used about a dozen times so far. I wash thoroughly to remove all soil, then run through dishwasher to sterilize them.
I also re-potted the SuperSweet-100 Cherry tomatoes. They are taller, hybrid, and more vigorous, indeterminate. Mostly I'm growing dwarf varieties, but these are my favorite cherry tomatoes.
