Turns out anything can be a planter, even that old pickle jar! Check the source tutorial to find out how you can make your own.

Very nice, but I would like to know, does the plant inside gets enough CO2 and O2 when the jar is kept closed? Great idea.
Apparently the terrarium is fairly self-sustaining after the first water. The tutorial suggests unscrewing the lid and watering if it begins to look dry. Hope that helps 🙂
