Sheena at The Little Red House uses glass terrariums (these are her pictures):
Inside are rocks, moss, active carbon...
Some examples of plants you could plant in your terrariums can be found here.
Can you see where her terrariums are?! I think they look gorgeous sitting on a shelf unit or out on a kitchen table or window sill. For full instructions and other links, see her blog.
What I'm trying now are these water bottle feeders. With the most ingenious watering system idea:
this image and the following from Self Reliant Sisters
I know you have water bottles or soda bottles lying around the house or gathered around your trash/recycle cans in your kitchens.
All you do is cut the bottle in half (please do not stab yourselves) and invert the top into the bottom.
By adding a 1/8" piece of rope or yarn you've constructed a self-watering wick. Water your soil and then fill the bottom of the bottle with water, refilling only as needed. For people like myself that can easily forget to feed something (RIP gerbil) this is ideal as you only have to water when the base reserve is out. Also ideal for college dorm room sills or for young kiddy-winkies to be in charge of.
