It all depends on the on plants your are growing. You mention
Darlingtonia later on ==> this plant and Cephalotus can make easy
prey for fungus if the temp is to high and the light to low. Place
an aquarium thermometer in your terrarium; mine does fine between
75 and 80 degrees F.

> 2) How often do I need to change soil, if at all? The terrarium is filled

Between every 9 months to two years. I don't quite understand why
some compost (soil, peat) will last longer than others. It probably
has to do with water quality, temp., whether it was exposed to
fertilizer or not.

Pinguicula generally like (sometimes alot) less light than
Sarrs. I have seen other people grow them near the rhizomes
of Sarr.

If you bought it dried don't hold your breath, you'll pass out
or something. If the moss was completely dried then it is dead.

I know that line. Clive Barker's "Hellraiser" comic book.
Man, "Jihad" was great!
