Gets kind of big for most terrariums
There are a number of types of terrariums: 1. Terrarium kits are available that focus on certain plants and animals. E.g. desert or cactus terrariums 2. Hanging glass terrariums are really snazzy and a great piece of decor for your house 3. Plant terrariums focus on plants and don't contain animals 4. Animal terrariums can be a home to lizards, bearded dragons and snakes. 5. Aquarium terrariums are terrariums that have been made using a fish tank.
The answer is charcoal.
The best place to buy all kinds of activated carbon/charcoal products (over 150) is www.BuyActivatedCharcoal.com
The name is Kingsford charcoal. It is sold all over the United States.
Terrariums make a shelter for plants. It is a small container that plants are kept in to keep healthy. Once they are healthy enough, they can be put into a garden.
You can purchase charcoal BBQ at your local Safeway store. You can also buy charcoal for a cheap price at Costco because they always have cheap prices and coupons.
