Sprout Seeds and grow them in unclorinated and non-flouride water an in a canning jar. I do and consider my sprouts to be "my vegetables". I use a Berkey portable water filter with a chlorine filter and a floride filter (since my Beloit, WI tap water has both). It cost me about $250 (with no regrets). I never drink tap water in my town, except occasionally at work (in the coffee). At home I cook and drink only filtered water (and use it for fermented foods+sourdough), and store more for power outages. I bought Sprouts on 9/14/2014 to ensure that if the economy collapsed that I could feed
my family very-healthy vegetables (and especially through long winters, and indoors in-town). I especially like Fennugreek seeds--good for blood sugar control. At age 64 (lean, but not particularly mean) sprouts "perk me up" more than any vegetable I have ever eaten. They are filled with healthy vitamins, enzymes, and photochemicals. Most of the sprouts I eat are called micro-sprouts. I eat them when they are about 1" in plant-sprouts. But this year my sprouts are 2-years old and aging very fast. This Spring I will also become a "Johnny Appleseed" type of guy, who goes out and plants my seeds that are getting old enough
to not start up regularly (says the website where I bought them, though they are still starting fine at my house). I got organic
sprout seeds from "sproutpeople.org". I over-bought as a first time buyer and experimenter. A 1-lb bag of sprouts will make about 48 quart jars (about 3/4ths full, unless you let them grow to 1.5") and cost anywhere from $8-$15 dollars per pound depending on what you buy. I eat these raw, for a snack, throw them in eggs; and I can juice them. What I have is still good. I eat the seed
pod shells also. I especially like daikon radish and fenugreek. So, if you don't have soil, you won't have weeds, if you grow sprouts in a canning jar (and it will smell good so long as you water+drain at least once daily), about 1 heaping tbsp per jar. The sproutpeople.org web site has lots of info on the health value and how long to soak. I really like using canning jars (1 qt) because I can see how fast they grow. Sprouts to me are a fail-safe way of best-eating of the easiest and best vege's available. They store well (I keep in a room averaging about 60-70F year round. If you go camping for week, take some sprouts with you and a canning jar (and filtered water). You can eat them after soaking 8+ hours, or wait a few more days for them to grow 1/2"or 1". I don't get hungry, nor "junk food cravings" when I eat sprouts, which is why I eat them. Now I'm going to pick a place to plant them "wild" (where few people go) and see what the plants look like as they mature. Maybe I will get lucky and find some foraging. I have found old gardens (where once homes stood), but I was dumb back then and couldn't identify the garden
plants re-growing year-after-year from seed (at the season that I found them).
