Possible terrarium containers?? Suggestions?

[jenilee]

Hello!!
I have a few beautiful containers that need flowers....and I'd like to get into some miniatures!
BUT...I have a few concerns:
The domed containers won't have much, if any air circulation....problem? They would when I take the top of to water I guess....on that note, how often would you water a totally enclosed set up?
None of these will have any gadgets of course (misters, etc)....just plants.

Any thoughts?
Suggestions on minis?
The dome is about a foot tall and six inches wide.
The glass "thing" is about a foot diameter.
The hanging globe has about 6-8 inches inside height and about 4 wide....plus the hole is only wide enough for my fist so that limits my planting ability.
(None of these are my pics....just pics I found of them....haven't had the chance to dig them out of storage)
