Wheat grass juice gives a punch of nutrition with vitamins, minerals, amino acids and chlorophyll, all of which help to improve overall health by boosting the immune system, increasing energy and building red blood cells. Buying wheat grass juice has become popular and convenient, yet growing and juicing your own at home cuts cost and allows you to consume the freshest wheat grass. To grow wheat grass, you need only a few inexpensive supplies, but in order to juice it, you'll need a special wheat grass juicer. Many different juicers are available, including electric and manual models, making it affordable to juice wheat grass at home.
Add 1 cup of wheat grass seed to a glass jar, and fill with filtered water just to cover. Place the lid on the jar, and set the jar aside for 12 hours. Pour into a paper-lined colander, then rinse the seeds, drain and set aside for another 12 hours. Repeat this process one more time, after which the seeds should have sprouted small roots and be ready for planting.
Fill a seed tray with potting soil. Water the soil clear through to the bottom, mixing with hands if necessary to combine well.
Spread the sprouted wheat seeds over the top of the soil and mist lightly. Place an inverted seed tray over the top, and set aside in a place out of the way. Mist the seeds each day with water to keep moist.
Remove the top seed tray after approximately five days or when the grass is about 2 inches tall or more. Set the tray in front of a south-facing window where the grass will receive adequate light to turn green and produce chlorophyll.
Harvest after about 10 days or when the wheat grass is 7 inches tall. This is the optimal time, when the nutritional value of the grass is at its highest and freshest.
Juice wheat grass by cutting a handful of the grass just above the soil. Roll into a ball and place in a wheat grass juicer. Drink immediately after juicing.
Store unused wheat grass in the refrigerator. Place the seed tray with the grass inside a plastic bag, and set in the refrigerator until ready to use. Use the wheat grass within five days.
