Answer: Ryegrass seed will grow for a few weeks in a shallow container of soil inside your home, but since grass requires direct sunshine to remain healthy you should plan to replace the grass frequently. Sow the seeds in moistened potting soil and provide bright light. Once the blades reach 5"-6" in length they'll begin to bend over. You can prolong their attractiveness by clipping the tops, much like you would mow a lawn. After several weeks of indoor growing, the plants will start to look shabby and should be replaced. A substitute for ryegrass is millet, found abundantly in wild bird seed. This, too, produces fine blades and will look nice indoors for several weeks.
