Successful crops of wheat, oats, and barley were produced in a growth chamber in 60 days with light from fluorescent and incandescent bulbs at an intensity of 1200 to 1500 candle power. Full light was used for 18 hr. per day and a low intensity of incandescent light for the remaining six hour period. The experiments indicated that the light requirement of the oat crop is somewhat higher than for wheat and barley.
