If you guy's have suggestions on which minature orchids I could grow I would appreciate it.
Hmmmnnn!
Well, first you have to consider what is the MAX and MIN of both Temperature AND Humidity...
Once you have established this, you can then decide on the varieties you want to grow.
I am also biased to Dendrobiums...and there are A LOT of mini species/hybrids out there. One of the harder to grow is the Den. cuthbertsonii, flowers that last upwards of a year! Another could be Den. senile.
Though you have to figure out exactly what you want (also), like, how long the flower lasts/colour/do you want scented/size of flower.
I recently posted a picture of a Cleisostoma sagittiforme, wonderful little flower and scented and the orchid is about the size of a folded (width wise) dollar bill.
Though I would also consider some of the "Jewel" orchids too. They can be very compact and the foliage display is great to look at year round.
I have been reading up on terrariums a lot lately, since I also grow a lot (for me) of "Jewel" orchids. My problem is the humidity they need, and lower levels of light. As well as some of my Dendrobiums with similar needs.
Eventually, it will come down to your tastes and the effort you want to put into the final set-up...and from what I have seen so far, it is gonna be very wonderful to look at when you done.
SUCCESS!
