This is my first post and i have a few doubts which i believe you all could
clear.
They are :
> Instead of using glass bottles or spheres, can i use a large PET bottle or a
can?
> Instead of a common theme of an aquatic ecosystem, can i have an ecosystem in
which i ass soil and some land plants?
> How long should i wait before sealing the ecosystem?
Waiting for replies........
