Soaking seeds aids faster germination. It is advisable to rinse wheat berries before sprouting to remove dust from shipping. Measure out enough seeds to create a light layer on the seed tray you use to grow the grass. For a 16″ x 16″ tray, use about two cups of seeds. Soaking: Pour cold water into the bowl of seeds. Add about three times as much water as you have seeds. Cover the bowl with a lid or plastic wrap and place it on the counter to soak for about 10 hours, or overnight. Drain the water from the seeds and replace it with more cold water again, about three times as much water as you have seeds. Let it soak for another 10 hours. Repeat the process one more time, for a total of three long soaks. By the end of the last soak, the seeds should have sprouted roots. This means they are ready to plant. Sprouting: Line the seed tray with a food safe cloth, to prevent the wheatgrass roots from growing through the holes in the bottom of the tray. Spread an even one-inch layer of organic compost or potting soil in the seed tray. Spread the seeds in an even layer, slightly spaced out across the top of the compost or potting soil. Lightly press the seeds into the soil, but don’t completely bury them. Water the tray lightly. Covering the seedling tray with a damp cloth or plastic will help retain moisture. It’s important to make sure the seeds don’t dry out in the first few days after you plant them. Keep them damp as they root themselves in the seed tray. Lift the cover and water the tray thoroughly in the morning so that the soil is wet, but not completely waterlogged. A spray bottle is recommended for watering and adding moisture to a cloth cover. Place the tray in a window with no direct sunlight. On the fourth day after planting, remove cloth cover to prevent the seeds from sprouting through it. Continue watering the sprouted grass once a day. Once the shoots are mature (about 6 inches tall) a second blade of grass will begin growing out of the first shoot. This is called “splitting” and means that the grass is ready for harvesting. After cutting off the first harvest, leaving roots and about 1 inch of grass stem intact, keep watering the wheatgrass to produce a second crop.
