Wheat grass contains high levels of vitamins, enzymes and chlorophyll, and many people use wheat grass to improve their immune systems or provide a boost of energy. Wheat grass juice is often used in smoothies and fruit juice blends. Prepared fresh or frozen wheat grass juice can get expensive if you drink it every day. You can grow your own easily and have fresh wheat grass whenever you want it.
Soak wheat berries overnight in a clean jar or bowl filled with cool water. Wheat berries (also called wheat seeds) can be found in most natural food stores or from juicing or sprouting supply catalogs. You will need enough wheat berries to loosely cover your tray. One cup of wheat berries will cover an 11-inch square greenhouse tray.
Fill the tray with all-purpose organic potting mix. Wet the soil so that it is moist and crumbly but not waterlogged. Make sure the tray has adequate drainage holes in the bottom.
Drain the wheat berries and rinse them in a sieve under running water. Spread the wheat berries over the soil in the tray and cover them very lightly with additional potting mix.
Cover the tray with its lid and place in a location away from direct sunlight where the temperature is about 70 degrees Fahrenheit. Make sure the lid has several ventilation holes or mold may develop.
Check the tray twice a day and water with a mist bottle as needed to keep the soil evenly moist.
Remove the lid after three or four days or when the wheat grass is about 2 inches tall. Continue to water regularly.
Harvest the wheat grass when it is 6 or 7 inches tall. Depending on your growing location, this may take seven to 14 days. Cut the wheat grass with a sharp pair of scissors just above the surface of the soil.
Process the wheat grass in a juicer or blender. Cats also enjoy eating fresh wheat grass, but you should give them small amounts at first to see how their individual digestive systems will handle it.
