Honestly, it never occurred to me that it would hurt my plants. As soon as I saw what happened though, I knew exactly what the problem was. Luckily, this is the grey tree frog vivarium. All of my hardy and inexpensive plants are in there. Had it been my red eye tank, I think I may have actually cried.
Was it the acidity of the fumes that did it? I had a light fan running but nothing too much because I didn't want to dry out my plants.
