I have tried bamboo with my pokies, but it got mold very fast. corkbark is very good. I have used driftwood pieces aswell with no problems. I found a "new" kind of wood? its roots of sum sort of plant at a petshop. it looks like very lightly coloured driftwood, but is not heavy. i have a nice piece with my Psalmopoeus pulcher for about 3 weeks now, and still no sighn of any mold.

I added a pic of it. This piece is about 35cm high and cost me R25

Wow, Pink T I love the look of your enclosure !!!! Thanks I will try all of the above anyways as I think temperature and humidity in the house itself also influences it a lot. That may be why what works for one does not work for another. Also glueing the bark etc onto a rock sounds like a really great idea !!!!! Then you are able to keep nice pieces of cork, bark, bamboo or whatever for a long time. You know that you sometimes find this perfect piece and you think: now how am I going to get this to NOT rot. I love this forum, thanx guys.
