I just wanted to make a comment about mold. Mold is most often an indication of too much heat with not enough air circulation. Warm, stagnant air combined with a very wet environment can encourage mold growth. VFTs will do well in an open environment (in a pot on a window sill or outdoors). They don't have high humidity requirements like some CPs do, so a terrarium is not a "must". If you just prefer to grow your plant that way, just make sure it gets good air circulation, lots of light and not toooo much heat (like from an incandescent bulb) as an enclosed terrarium can heat up pretty quickly.
Just my moldy 2-cents. [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]
