Also, by reducing the spacing from 36 X 24 to 18 X 12, that is 4 times as much seed planted for less than double the poundage, so it is also actually a huge REDUCTION in production per plant.
Good points. Like I said, I take what I like and leave the rest from all the methods. I have raised beds and they are just 3 x 8 for the most part. Experimentation is part of the fun for me.
I only have 176 sq. feet to experiment with. Hubby has about 1000 sq ft. So far he likes the double dug beds, and decided to build up the soil into raised beds and mulch in between to walk on. Other than that, its pretty traditional methods.
