That Wim Hof method is extreme, and I'm not sure how you do it.
I remember watching the video you posted not too long ago about it.
In my neck of the woods it would not require much preparation, just walk out side and your good to go.
Green beans are prolific, and always fun to grow.
It seems like you are really enjoying growing stuff, and with experience the yields only get better.
Pondering what to grow is always a lot of fun, we try a couple new veggies every year.
With Christmas right around the corner, I hope you and the Misses have been behaving yourselves.😁
