The corn plants and trays of lawn grass need to be started from seed 2-4 weeks prior to the class meeting. These can be grown in the greenhouse or under grow lights. Both require adequate water and fertilizer. Grass seed should be sowed in loose soil to produce a carpet of grass. Allow to grow until inflorescences appear. If seed is available, plant a tray of Kentucky blucgrass (Poa pratensis) and Bermuda grass (Cynodan dactylon).
Samples of grains can be obtained from farmers or purchased from biological supply companies.
