Windmill, here's what I found in my Pocket Encyclopedia of Vegetarian Cooking:
Put 2 tablespoons of seeds in a jar and soak them in plenty of lukewarm water overnight, to encourage them to germinate more quickly.
Next day, drain off the water. Put the seeds on a suitable tray or leave them in the jar. Put in a warm place but not in direct sun (the airing cupboard is ideal). They need good ventilation and a constant temperature of 13-21 degrees C (55-70F). Remember to allow enough space in the container for the growth of the sprouts.
Every night and morning pour warm water over the seeds. Turn the jar, if you are using one, upside down so the water can drain away completely. If not properly drained the sprouts can go mouldy, but be careful not to rinse them so vigorously that you damage the delicate shoots.
Grain sprouts take 2-3 days, beans and lentils 5-7 days, to be at their best. When ready, give them a final rinse. Keep in the fridge for up to 4 days. Use an airtight container with a double layer of kitchen paper or muslin at the bottom to absord excess moisture.
HTH. I haven't tryed it myself but I think I will now!
Let me know how if it works.
