Those of you who have grown barley, when did it head and how tall was it? Mine is heading after a little less than 60 days. The 2 row is 12-18 inches tall and is pretty much all headed and the 6 row is uniformly about 12 inches tall and starting to head. i kinda expected it to head when it was maybe 2 1/2- 3 feet tall. It looks great in that it looks healthy, bright color, hearty looking, but I'm a bit worried because the amount of sunlight per day and overall fertility is marginally ok.
