houseplants in aquarium etc/vivarium

[davholla]

I love houseplants (mainly Christmas cacti, African violets, orchids and gloxinia).  However I have a problem with mould in my house and so want to reduce the humidity.
Has anyone kept any of these in tanks?  And if so any ideas?  Would this solve the problem?  I guess sealed containers would be good for the plants and the house as the house would get less humidity and the plants more.
