One way to ensure you receive the nutritional benefits of wheatgrass juice is to grow your own from the wheat berries. The wheat berry is the whole grain of wheat that comes from the plant before it is ground into flour. Wheatgrass contains vitamins A, C and E, and is high in B vitamins. However, the wheatgrass can also cause nausea or dizziness when you first begin to drink the juice, and should be taken in small amounts at first. Once started, your wheatgrass should be ready for harvesting within a few weeks.
Fill your bowl with lukewarm water and put your wheat berries into the bowl. Set the bowl aside for 8 hours.
Mix together equal parts of compost and potting soil to fill the starter tray.
Use a colander to drain the water from your wheat berries. Rinse them under running water for a few seconds, and then let the water drain from them again.
Add a single layer of the seeds on the surface of the soil in the starter tray. Spread 1/2 inch of soil over the seeds.
Add enough water to your tray to moisten the soil. Moisten the soil with water each day.
Place the cover over the starter tray to keep the moisture inside. Remove the cover after about three days, when the wheatgrass has grown to about 2 inches in height.
Put the tray in an area where it will only receive indirect sunlight, so that the sun does not dry out your plants.
Trim the wheatgrass with scissors to harvest what you need once it reaches about 7 inches in height.
