Q.What plants should I use
Hello! I am trying to create a terrarium for a science experiment on how plants effect and are effected by their environment and want to build small environments to test this out. Hoping this is a lower price range project, but what plants can I use for a miniature environment that will simulate real life environments (industrial)?
Mosses are often used in terrariums, along with other small plants:

As for simulating industrial environments, you could choose either plants that are often found growing in industrial or contaminated spots (pioneer or "weed" species like Arabidopsis, which is very environmentally tolerant) or plants that are intentionally planted to improve or stabilize industrial sites (Carex sedge might be an option).
