4th Aerobic Sampling (Day 3) on 16 December 2010 (Thursday)

It's not apparent from here, but there is a tube linking from the orange to grey digestor for simultaneous aeration of both aerobic stages:

With the exception of the commercial fertiliser (Extreme RHS Column), the rest of the potted plants have started growing or sprouting:
