So how many tomato plants to you routinely grow? You could end up with quite a few doing a batch every two weeks. That sounds like a good system.
Of course, I'll have a few green as fried green 'maters, and some fresh ripe ones with salads, etc..
I do like having the extras in case I get whacked with a late freeze or cutworms (I do use foil) or something.
