Still air
Still air needs to be higher then 99.5. I think it's 101-102. So 101.5 would be optimal.
One absolutely MUST try cucumber is Suyo Long. It's an open pollinated variety, grows about 12" long, tender skin, never bitter. I've not made pickles with it, but am convinced that it'd be a fantastic pickler if used young. http://cdn1.johnnyseeds.com/images/Product/large/333G.jpg
Ohhh, I will try those! Thanks!
