Harvesting Sun chokes First Year

I planted 11 sunchoke tubers in late May of this year. They are doing quite well and healthy. I want to harvest them sometime this fall, but I’m wondering if I should wait til next fall after they establish themselves and matured stronger .Is it better for them to establish and mature another year? Or should I go ahead and harvest them this year?

I think in most areas they are grown, they are fine harvested in the first year. I do often leave them another year, but my area is a little cool and wet for them to do well.
If you want to increase your stock, replanting the tubers with increased spacing won't do any harm.

There's some current talk about spacing over in https://permies.com/t/sunchokes
