1. Soak 220g of wheat seeds - ideally organic - overnight (or for 8 to 12 hours).
2. Sprout the seeds in a jar for the next 16 to 24 hours, rinsing the seeds well three times a day.
3. When a short white "tail" becomes visible on the seeds, plant them on top of 1 inch of soil in an A4ish sized seed tray. Basic potting mix or top soil will work fine, although peat moss is an important ingredient to look for in your soil. If you want to add peat moss, the ratio is one part peat moss to three parts soil, filled half way up a two-inch deep tray.
4. Water the tray and then cover the seed to keep from them drying out for the first three days.
5. During the first three days of growth, water once a day in the morning and really soak the soil (until the tray drips is a good sign you are watering enough). Then lightly mist your seed in the evening. (Lift cover off to mist seed.)
6. On the fourth day, take off the cover (roots should begin to take over your soil), water heavily once a day and keep the grass in the shade (never direct sunlight).
7. For mold problems, increase your air circulation with a fan or air conditioning to keep the temperature between 70 and 80 degrees Farenheit ( 21 - 26 degrees Celsius).
8. Using scissors, harvest the grass when a second blade of grass appears on the grass blades, or when the grass "splits" toward the bottom of the blade. Average growing time is 7 to 12 days depending on the weather, but still always watch for the second blade of grass as you can never judge by how many days it has been growing or how tall the grass is.
9. Only harvest one time. Cut grass will store in the fridge about 7 to 10 days, then start the process all over again with new seeds and soil.
You can buy wheatgrass growing kits from some select health-food shops.
