I relatively recently activated the Ischia culture from sourdo.com as well. Once I got the culture established, I then spent the next several feedings transitioning it from the flour I activated the dried culture in to the flour I maintain it with (I'm not sure if this is strictly necessary, but I was trying to be cautious). Once it was established, I started refreshing it every 14-15 days. The duplicate entries are because I decided to split the initial culture in two after the second feeding. Depending on the ambient temperature, the refreshed cultures usually double or triple in the 6 hours before they go back into the fridge. I've really been enjoying the Ischia, hope you do so as well.
