Terrariums and Succulents

I bought these beautiful succulents hoping to plant them in my terrarium.  They were the smallest plants the store had, small enough to fit.  When I looked for advice on the web about terrariums and succulents I learned that you can do it but it's not such a good idea.  I know I should have done more research before buying the plants.  I was just too eager to get started.

I learned the reason why succulents are not so good in terrariums is because they require a dryer atmosphere with air circulation.  The terrarium is damp and closed in.  If I use the succulents it might still work out, at least for several months.  But I want a longer life without watching the plants die.

I fell in love with these plants and did not have the heart to return them. Besides, they only cost about three dollars each.  

While I was at the store I bought a bag of colorful stones for the bottom of the glass container.  This will be a place for the water to drain.  I bought activated charcoal to keep the terrarium fresh.  The same activated charcoal that's used in swimming pools.

On the box:

"Removes heavy metals, odors, discoloration, organic contaminants."

I also bought some gravel to put on the soil between the plants for an attractive appearance.

A few sites suggested putting small decorative figurines.  As long as it doesn't look silly I might try it.  One site had a tiny plastic cow in the terrarium!  That's not for me. 

Now what am I supposed to do with these great looking plants?
I'm going to put them in regular pots while I look for plants better suited to terrariums.

I'll let you know how things are working out.  I need to clean out some old flower pots to make new homes for the plants.
