The way I planted mine in the main garden was two rows at 12" spacing, skip 32" then two more rows at 12" spacing, then another 32 and 12. At 6" in the rows instead of 8". What you suggest makes sense. I'll just fertilize heavily. It will be so thick there will not be any sunlight getting to the ground so I can't plant anything else in there.
I plan on dedicating one of my six beds to corn. According to my planting guide I can start planting the middle of February, I may wait a week or two though to be sure. Since they are packed so tight I want even germination. I don't think I can replant because of shading issues. I like to stagger the corn planting every two weeks so I'm eating fresh corn over a reasonable period. I don't think that will work here, again because of sunlight/shading concerns planted that tightly. In the garden I had room to spread it out.
