I used a 1500ml starter, which got the main batch going after about 3 hours, pretty quick. I wouldn't use an airlock, just leave a decent opening in the fermenting bucket lid and clean the mess up the next day. It's a lively yeast.

When it's settled down I'll close the lid and stick an airlock in.
I'll let you know how it turns out. I guess 2 weeks to ferment out and cleanup, and a couple of weeks in bottles gassing up.
