If they are cut, there is often a second harvest during the next week. Several books on the subject are listed below. Sometimes production is in a greenhouse. The greenhouse method begins with laying thermal tubing on top of polystyrene, which rests on the ground. This is covered with black plastic.
Thermal tubing distributes heat from hot water heaters and functions as a root-zone heating system.
Next, a layer of compost or soilless potting mix is laid on top of the plastic about an inch deep. Soaked grains are spread on top of the compost mixture making sure each is in contact with the soil. The seeds are kept moist by watering as needed. Within a week the sprouted grains will be ready for harvest. Mr. King is very knowledgeable about the entire production system, from growing the wheat in the field, through dehydration and storage, to the production of the tablets.
