Hey, my name is Lisa. I wanna start making terrariums for my orchids and I’m starting my first build with a 12x12x18 tank. I’m using egg crate for the false bottom and want to glue rocks around it to hide the crate and build up the sides like a bowl to keep soil separate from the water feature. I’ve spent some time learning the basics for terrarium builds but there’s nothing like learning directly from people with experience so here I am. Right now I’m looking for something I can use to glue rocks to rocks and wondering if I can use hot glue or silicone, or maybe something specifically made for the task?
