Thanks for the replies
These terri's won't be housing any wildlife.
Was thinking that fauna itself can grow in harmony while the fake water feature just acts as a backdrop. There were several people I spoke to who are in the business of terrariums. They said the epoxy won't harm the plants. As long as the surrounding features are done properly i.e. potting mix/filtration etc.
PS: Both yours and GIna's terrariums sound incredible!
