- jar terrarium -
DIY terrarium. Bottom layer about 1-2 inches gravel, second add thin layer activated charcoal, third layer add about 4 inches soil. Then add plants and finally add moss. This is a high humidity terrarium so I keep it sealed with saran wrap. Make sure you pick plants that have the same care requirements, some like it moist, some a little more dry, other wise some will suffer! Finally spray mist with DISTILLED water only! I added 2 carnivorous plants, the Venus Fly Trap and the Octopus plant.
