Passion Fruit

I wish grow diaries would update the math for harvest. My flowering room is 50sqft. I light with 1200 watts of power. This is 24 watts per sqft. The plant covered 4sqft so light usage was 96 watts (4x24). Gram per watt should be 1.36 (130.1/96). I believe that if you input canopy size for grow room size the remaining calculations would be correct.
