CD and DVD spindle cases can be reused in a variety or purposes, but this is the first time I've seen them reused as a terrarium. With only a few steps you can make your own small terrarium that will grow over a period of days.
This is a very simple idea. It's somewhat surprising at how easy it is to use. The trick is that the CD spindle case can be used as a mini-propagator to grow plants. You should use the biggest CD spindle case that you can find, ideally something that was used for at least 100 discs.
1. Cut out the central column of the CD case
2. Make sure you patch any holes that this creates
3. Drill a few vent holes in the top of the case
4. Find a matching pot that fits inside of this
5. Add some compost, seeds, and water
This setup can also be used to start seeds for your garden or to grow plants that need humidity, like miniature ferns. The terrarium was made as a miniature living model of a rain forest. Moss and weeds from the garden were used for this.
We like the easy way that you can start growing seeds with this. You don't really need a large operation if you only want to start a few batches. Honestly, you could probably put together a nice array of planters using all of the CD spindle cases that you can find. It definitely beats throwing them out into recycling bin.
