With so many different ways to grow wheat grass, it can get confusing about what the best method is. Growing wheat grass at home, though, has less to do with the technique and more to do with using the best ingredients from the start to produce the best product in the end. Using the best organic wheat grass seed and potting soil helps ensure that the wheat grass you grow and consume will be at its highest nutritional value, loaded with plenty of healthy vitamins and minerals.
Place one cup of organic wheat grass seed in a glass jar and cover with filtered water. Place the lid on the jar and set aside for eight to 12 hours, then pour into a paper towel-lined colander to drain and rinse with filtered water. Let set for another eight hours, rinse again with filtered water, and let drain. Repeat this one more time, after which the seeds are now ready to plant.
Fill a seed tray to the rim with organic potting soil and wet the soil thoroughly with filtered water. Use a tray that has drainage holes in the bottom.
Spread the soaked seeds evenly over the potting soil in the tray; do not push into the soil or cover with soil. Spray the seeds just until damp using a spray bottle filled with filtered water. Place a layer of paper towels over the seed tray to cover and set aside for five days. Continue to mist the seeds each day to keep them moist, but not soaking.
Remove the paper towels after five days or when the seedlings are beginning to push the paper towels off. Set the tray in a sunny location such as a south-facing window where the sun will begin to green the grass. Keep the grass watered by setting the bottom of the tray on a water tray, allowing the soil to absorb the water without getting the grass wet, which can cause mold.
Harvest the wheat grass after about 10 days or once it reaches 7 inches in height. At this time, the grass has developed all the vitamins and minerals needed to be at its highest nutritional value. Cut off just a handful of grass to use per person and cut the grass down to the soil. The grass can be juiced and consumed. Place the rest of the uncut grass in the seed tray into a refrigerator to store until ready to use.
