No earth, just water and a couple of days: home-grown food
What you need:
Almost any edible plant seed can be used: beet, spinach, soya-beans, mung beans, fenugreek, alfalfa, lentil, radish, and grains for example. Easy to find in health food shops.
Glass jar
Gauze to cover opening
Elastic band to hold gauze in place
1. Put 2-3 tablespoons of seeds in the clean glass jar and fix the gauze with the elastic band over the opening.
2. Pour water in jar to cover seeds
3. Let seeds soak from anywhere from 8 to 24 hours. Bigger harder seeds will need overnight soaking, smaller, more tender can do with eight hours. The larger seeds will absorb most of the water.
4. Drain out the water and let the jar with the seeds sand aside, on a shelf, anywhere in your kitchen. Preferably where there is light.
5. From here on, twice a day, fill the jar with water and drain it out again. It does not matter in which position the seeds start sprouting, or if they are tossed around. What is important is that the seeds are never standing in water.
6. Depending of the type of seeds and how warm it is, it will take 3 – 6 days to have ready to eat sprouts. You can tell that they are ready when the root is about 2-3cm long.
