Hi Flo, just a little advice.
The best way to use your tunnel is season extension. Hardy Chicago is an early variety but there are a few others that are a couple weeks earlier: Florea, Ronde de Bordeaux, Improved Celeste/O'Rourke. You can also harvest later by planting varieties like Black Madeira, Col de Dames, Verdal Longue etc inside as well.
You will also want to be watchful for mites inside a structure like that.
Good luck and welcome.
