Here are pictures of each zone. We left the eco-column as was over the three week holiday and came back with some unsuspecting results. First of all our terra-zone has almost completely died and is now much like the decomposition zone. We thought we had created a cycle of water to keep the plants alive. Firstly we cut holes in the top to let oxygen etc in but the evaporating water may have used this to escape. And secondly the water may have simply filtered down into the decomposition-zone.
The decomposition zone was the most surprising, almost all off the materials we started with were gone but a small plant or weed had begun to grow inside it. We believe that this was because there may have been a seed inside the soil when we inserted it. The water has probably filtered down from the terra-zone and there is sunlight shining through the plastic creating new life.
The aqua zone was most impressive, showing a flourish of live ranging from our water weed to the snails and small unknown water creatures.
Over all our eco-column is two thirds successful which is definitely a plus, we had a fun and positive project to deal with and are now done.
Thanks from the team. :))))))
