Pros/Cons of buying seed potatoes VS?
I guess the VS would be finding unique varieties at say a farmers market or organic market etc.
Then if you do buy "seed" potatoes, and say you get 1 pound of them. How do you prepare them to plant. I just spoke to a sales rep from an online organic place that said a 1 pound order will seed an 8 foot row, spaced 8-12 inches apart. So for $3 (and shipping) you get approximately 8 plants.
What would be a good quantity of plants to produce say enough for a family?
If store bought/market bought potatoes are used, is there anything different about what you will get to grow from them?
