It depends on your style of growing and your height restriction. If you're running 36 plants under that 1000, 16 inches tall is about perfect. I run fewer plants and grow them bigger so I'd think 11 inches moving into flower is too short for me. If you're running aero, 11inches going into flower means your plants will be 4 ft tall in a matter of weeks. Basically, it all depends.
