I am new to the terrarium scene, but i have been thinking about building one for a while. here is my general idea for the structure. i think that i am going to fabricate a frame made out of wood, datoed to accomadate the plexi glass i am going to use. once that is done i am going to silicon the plexi to the wood. that is really the general idea, except for the roof which will be the same construction with a hinge on the outside. does anyone have some suggestions for a place to start. i am sorry to be so mundane but it is all so new to me. any advice would be greatly appreciated.
