The seeds are relatively cheap to purchase but we have found they are even cheaper if you buy in bulk (E-Bay - 8000 cress seeds for 99p) or even sprout organic pulses purchased from health food shops.
Sprouting is simply the process of germinating seeds and there are many suitable to choose from - alfalfa, soya bean (which are sold as bean spouts), fenugreek, aduki or mung beans, rocket and onion - just to name a few.
After soaking, which increases the seeds water content, they left somewhere at a temperature of between 13-21°C to germinate. Seeds will begin germinating within a day or two and have to be rinsed, depending on the seed used, between 2-4 times a day to keep them moist but not soggy. Depending on which seed is used, after 3-5 days they will have grown to 5-8 cms in length and will be ready to eat.
