Upvoted! (And I don't know, why you were downvoted) If we're doing software the open source way (and thus securing the sustainability of the software "eco" system), why not do the same for food production (and secure the sustainability of food production). Just this morning I talked to a woman on the Sunday market and she told me about a guy who, even thou he has his own green houses and makes a living doing that, gives all that info to who ever is interested (best produce to grow, best timing for the market etc.) Concentration of this knowledge (or even patents) in the hands of a few is bad, bad, bad.

There are two factors for growing food that I learned the hard way, "when to plant" and "plant temperature tolerances"

For when to plant, I use this web site, if my desired plant isn't on the chart, I make a best guess based on related plants:

As for temperature tolerances, googling the "hardiness of a tomato" is a great stepping stone.
