Its been a while since I had a terrarium, but I recently found two cool pieces of glass in thrift stores, so some tips would be great!
I have a large Pyrex jar, open top, about 14" in diameter by 16" tall, and a smaller stemmed bowl. I grow bonsai and orchids, but I might so something different with this. I have access to live moss (NC) and the usual big box stores. What plants should I consider for a basically a 5 gallon container and a .75 gallon one? Any soil tips?
