and what if i did aeroponics at basicly 8-10'' apart, or is 1 square foot needed? becuase i was trying to optimize my area for maximum yeild. 4x4 would have 36 plants in it at a 8'' spacing it would only have 16 at 1 per square foot.
another thought. what if i trimed the low branches that shot off to far to give more nutrients to the main stalk could that aid more vertical growth with the same yeild with out bad side effects?
