A self sustaining Eco-column must be able to survive for some time with out being watered by myself or my group members. We can do this by making the Eco-column a tropical environment we do this by putting a removable lid on the top of the Terra zone.
We water the plant for the first couple of weeks to make the soil constantly damp, so the earthworms don't die then we put the lid on and leave. The water will evaporate from the Aqua zone because of the warm environment. the evaporated water will rise up through the Eco-column until it hits the cooler lid on the Terra zone. It condenses on the lid and falls, making it "rain" constantly like tropical weather.
This forms a cycle in our Eco-column of constant watering itself therefore making it self-sustaining.
