I have decided to change the look of my terrarium again, and want to fashion an environment for the neps by gluing pumice stones together. It will look pretty cool, I think, but it will require a lot of glue.
What adhesive would provide the long-term holding power I need without outgassing the plants to death? I am a little wary of using epoxy for this reason. Silicone, while safer, will not hold long-term.
Any experience with adhesives in terraria that you can share?
Any help you might have is appreciated. Thanks again.
