I think that our Eco-column will be self susteaining over a period of 8 weeks because the spot that our Eco-column is placed in has a good sunlight spot which will help plant growth.

We also have healthy moist soil which is a sign of good nutrients in the soil.

Earth worms were also added to decompose any dead organisms and that releases nutrients back into the soil. At the Terra zone we have a small fern will will produce healthy amounts of oxygen for all the organisms to survive.

We have also added snails to the Eco-column and the snails will feed off the worms and the worms will feed off the decomposed leaves and plants.
