Pines follows these growing, harvesting, drying and packaging standards established by Dr. Schnabel. Never Grown in Greenhouses or Trays Pines Wheat Grass is grown in the same kind of glacial soils that produced the most nutritious wheatgrass in the research. It matures slowly, outdoors, during cold months. Freezing nighttime temperatures and cold days convert months of full sunlight into nutritional density, while the plant remains a short grass.
