Terrarium or Dish Garden?

Today, I had some fun making a few small terrariums.
Err... I mean dish gardens.
Thanks to Andrea and GardenWalkGardenTalk for highlighting this to me, I should be calling them dish gardens instead of terrariums because terrariums are enclosed and self contained.

I have chosen a collection of compatible plants; mainly succulents and cactus.

As such, there would not be a need to water them for the next one to two weeks.

Since there are no drainage holes, it is important to create a space at the bottom for water to flow to. 

I have used leca balls for this purpose. 

Moss or pebbles can also be used.

While I was designing the terrariums, my daughter converted her little ice-cream cup into a little planter.

Please share your experiences with terrariums or dish gardens.
