Canning vegetables in a water bath is not safe unless they are pickled.
You should not can low acidity foods in a water bath, no matter how many people tell you that their grandma did it that way, their mother did it that way, and they do it that way and nobody ever got sick. It's not worth the risk. Food poisoning can look like the flu or a mild cold or be attributed to another food source: it's impossible to know if unsafe home canned products have or have not made people sick.
I fully trust that BYC forum users have honorable intentions, and that none of them would intentionally give you an unsafe canning method that could make you or your family sick. The scientific facts are clear: systematic research has concluded that a pressure canner is the only safe way to preserve low acidity foods. Soups, vegetables, meats, seafoods, and the like are considered low acidity foods and will harbor botulism.
People will disagree with me and that's fine. I respect their right to prepare and eat whatever they want in their own homes. I must insist that the scientifically proven safe methods are given equal acknowledgement and that people new to canning are given the opportunity to make their own choices on these matters.

Food acidity and processing methods
Whether food should be processed in a pressure canner or boiling-water canner to control botulinum bacteria depends on the acidity of the food.
Botulinum spores are very hard to destroy at boiling-water temperatures; the higher the canner temperature, the more easily they are destroyed.
The page is very useful and I refer to it all the time. I encourage you to:
1) bookmark the HFP website and refer to it often
2) save up for a pressure canner!
ETA: Note that on all the food, vegetable, and seafood pages of the HFP website it clearly states: "Note: There are no safe options for canning these foods in a boiling water canner."
Just because you can can, doesn't mean you should.
