Juiced wheatgrass is potent and packed with vitamins and enzymes. Unfortunately, wheatgrass juice is rather expensive to purchase at a juice bar, especially if you're drinking it every week. You can grow your own wheatgrass for juicing, which is easy to do and will save you a bundle. You can buy wheatgrass-growing kits online, which contain everything you need, including the seeds, growing medium and instructions -- but usually not the juicer. If you want to go the ultra-inexpensive route, you can purchase your wheatgrass seed in bulk on the Internet or in smaller quantities from your local health-food store and follow these steps to grow and juice wheatgrass.
Soak 1 cup of dry wheatgrass seeds in a large bowl filled with water for at least 6 hours or until the seeds sprout. Pour the bowl's contents through a strainer. Remove the sprouted seeds for planting.
Prepare your wheatgrass tray. Use a seed tray or cafeteria tray to grow your wheatgrass in. Fill the tray with 1 ½ to 2 inches of an organic topsoil and peat moss mixture (equal parts).
Spread the sprouted seeds over the soil mixture in the tray. Spread the seeds in a single layer but touching each other.
Sprinkle a thin layer of peat moss over the seeds. Cover the tray with a top tray and place it out of sunlight and at room temperature. Water lightly or mist with a spray bottle every day to keep the soil and peat moist.
Remove the top after about five days. Place the tray in indirect sunlight for 7 to 10 days to allow the pale grass to turn green and continue to grow.
Harvest the wheatgrass when the wheatgrass is 7 inches tall or when it begins to fork at the base. Grab a clump of wheatgrass in your hand and cut it across the base using clean, sharp scissors. Harvest the entire tray of wheatgrass at once.
Feed the wheatgrass into your juicer. Try to keep all the grass blades going in the same direction. One tray of wheatgrass will usually produce anywhere from 6 to 10 ounces of juice.
