I made this really cool looking terrarium, you can hang it everywere. I made it all out of scraps, recicled wood, innertube, paint find in the street and recicled plaxiglass! I m going to make another one (with the pieces i m showing in the steps) for the shower! I will put plant of Potus, they really like umididity in teir air roots.
I find the dome of the main one in the street, and the one I show in the steps is given to me by a frend, it was his motorhome window.
You can find them in junkyards.
The globe need very little wather couse it keep the dirt from evaporated too much, so it really look cool but need very few care, if you choose the right plants.

(step 2)
You shouldn't need to add CO2 for several reasons:
1. Plants exhale O2 during the day, but they exhale CO2 at night. The exchange is somewhat weighted toward eventually using up the CO2 BUT
2. Unless you are trying VERY hard for a perfect seal, there is enough airflow to keep the plants healthy. Of more concern is dialing in the perfect amount of airflow to keep the humidity at a moderate level. Too wet will promote mold, too dry and the plants won't be happy.
The plants won't grow as fast as if they had a super abundant supply of CO2 BUT
3. You really don't want terrarium plants to grow fast. Most people grow terrariums for their extreme low maintenance, which means you won't want to be in there trimming all of the time.
Of course if you had some high humidity vegetables or herbs (not many out there) growing in a terrarium, then CO2 might increase your yield.
