Thanks. I take extra care with all sanitation, cleanliness is next to godliness. Too much time invested into an average batch to worry about risks of unwanted infections/nasties. I just wanted to ensure a seperate set of 'soft' (plastics, tubing, etc) wasn't required.
As for preventing oxygen exposure in the starter, that is counter intuitive to me, so great heads up! With Brett's and s cerv's need for oxygen, never would have guessed.
