I’m not entirely used to the idea of replanting tomatoes when you grow them from seeds. The technique (here for example, or here) is so different from what I developed for boonies. With boonies, you sprout them, and there is no concern about darkness for a new days. You fertilize with an indoor strength fertilizer from the start, and keep the plants warm and in soda bottle greenhouses.

Tomatoes, by contrast, you must watch like a hawk when they sprout so they don’t  grow too much. You don’t fertilize until they have true leaves, and then only once or twice. Water is otherwise enough. You replant 2-3 times perhaps, every time they outgrow their “container”. You replant most of the plant into the ground in order to  create a deeper stronger root system. The final pot depth should be a minimum of 12 inches deep. (I think my tomato pots last year were at best 6 inches deep. Oops.)

By the end of the weekend, I want all my tomatoes into 6 inch pots.

The new boonie peppers are getting sizable enough that I should consider replanting them at some point, try a more tomato-like technique.
